How do I know if my 2002 coronary stent is MRI safe? Guidant Multi-Link PentaRef #1008057-15LOT 2042332 OTW
Karen, Highland, California, USA, June 27, 2019
Safety within the MRI community is being addressed, but needs additional information and updates. No longer can all stents be considered safe. the "conditions" set forth by MRI safety.com and Dr Shellock , must be adhered to and documented. Patients must! get the implant information in order for the proper field strength,parameters and SAR settings to get utilized. Long term effects and possible patient harm are unacceptable. you cannot "guess" if the stent/s are safe. nor theorize since they were manufactured or implanted prior to 1996-7. Safety is everyone who cares for the patient/s task. Technologists cannot assume your stent is safe without checking. I am a registered RT(MRI) technologist with 29 years MRI experience. if you are a patient get your implant card, carry it with you and be informed, NO CARD NO MRI PERIOD.

My dad has his biopsy done in Korea and was advised to have an MRI. But, he has the SeQuent Please (2.5x15mm / Ref:5021433 / Lot 12|03809) stent produced by B. Braun Melsungen AG. And, I wonder if this is safe for MRI?

To all readers: there was a very interesting and pertinent article that recently was posted at theheart.org / Medscape. This is a professional site and not accessible to patients so, if your physician is not sure whether or not you can have an MRI safely, have him/her read this piece. The article is written by Dr. Melissa Walton-Shirley, a Kentucky-based cardiologist. It is an extensive look at the specific issue of heart patients getting MRI exams. The article is titled, "Cardiology's Biggest Lie: No MRI for Your Device Patient" and concludes by saying, "It's high time to crawl out and expose cardiology's biggest lie, so here goes: Most of our device patients really can have an MRI safely after all." Enough said.

Darren - Interesting. One would have to assume that the MRI imaging facility and cardiologists worked this out before-hand since it sounds like most people in the trial had stents. Hopefully. In any case, you can check the specific stent at MRISafety.com and then check with the researchers to see if they followed the recommendations for safe Tesla strength.
Angioplasty.Org Staff, Angioplasty.Org, June 29, 2014 |
I had my stent done transradially in April 2013, I was then involved in a stem cell trial which involved 4 cardiac MRI. No objection was made or even mentioned on consent forms for the MRI, so I assume most are safe.
Darren F, Perth, Australia, June 15, 2014
Lisa -- This is outside of our field, but check out MRISafety.com and see if they have any information on this.
Angioplasty.Org Staff, Angioplasty.Org, June 14, 2014 |
I have stainless steel screws and stainless steel rod in my spine. They tell me it is not compatible with an MRI. My Dr. is trying to order a brain MRI. Since the MRI would be on my head and not my back would it be safe to have it. Please help. I'm Getting different answers .
Lisa, Palm Harbor, Florida, USA, June 9, 2014
Call the cardiologist. If you did not get a card, they should be able to send you one or refer you to a patient coordinator at the hospital who will take care of that. The type of stent including size and diameter is part of your patient record.
Angioplasty.Org Staff, Angioplasty.Org, May 23, 2014 |
Received a stent at local hospital. Did not receive a stent card. Should I get it from hospital or my cardiologist? No one mentioned a stent card nor gave me any info of what kind I have. Who is responsible to give me this information?
misspinky, Texas, USA, May 18, 2014
An open magnet does not work the same way as the regular magnet. You can not assume stents or any other implanted device is safe. You must go the mrisafety.com. If the device has any "conditions" you must go to the company's website and look up the restrictions, i.e. gauss, etc. I work on a 1.2 open and we are constantly looking up implanted devices (mostly stents).
Teresa, Topeka, Kansas, USA, April 29, 2014
LM in Philadelphia - If your grandmother had an angioplasty done in 1994, the likelihood of her having had a stent placed is relatively low, but we certainly could not rule it out. The first stents were approved by the FDA in 1993 and 1994, so stent placement was not routine, unlike today where 90% or more of angioplasties involve stents. A CT Angiogram is a non-invasive test that most likely would show a stent. If there was a stent, it probably would be a Palmaz-Schatz bare metal stent which, according to Dr. Frank Shellock's web site, MRISafety.com, is safe for MRI imaging if the Tesla strength is 1.5
Angioplasty.Org Staff, Angioplasty.Org, July 26, 2014 |
Urgent question: my grandmother is from Florida and is visiting PA. She had angioplasty done in 1994 and 5 bypass in 1996. There has never been mention of her having stents. She is in the hospital in PA. They can not determine if she had a stroke. They want to do an MRI but will not until we have more information on if she stents or not. All the medical records are archived so it will take days to receive. IS there any test or imaging that can be done to determine if she has a stent? We do not think she has one but they will not complete the MRI. This is urgent.
LM, Philadelphia, Pennsylvania, USA, July 25, 2014
Nate on Georgia - We do not have the specialized expertise on this matter but would suggest you check out Dr. Frank Shellock's web site, MRISafety.com. He has done a significant amount of work in this area and you might find some resources there.
Angioplasty.Org Staff, Angioplasty.Org, March 17, 2014 |
I am a MRI Tech. I follow the traditional guideline that most stents are safe especially in the more current years under 3T. I'm working on an open unit at .3 T (low field) but unlike 1.5 or 3T horizontal field, the open is a vertical field. My radiologist has raised concern that stents may not be safe on these low field open magnets because of it being a vertical vs horizontal magnet field. Help!!!! Do you think these stents are safe on the open low fields?
Nate, Georgia, USA, March 12, 2014
Larry in Missouri - According to the MRI Safety database, compiled by Dr. Frank Shellock, the Palmaz-Schatz stent you are describing is MRI safe at a setting of 1.5 Tesla.
Angioplasty.Org Staff, Angioplasty.Org, December 20, 2013 |
I had a J&J Palmaz-Schatz stent place in my Right Coronary Artery in 1996. I need an MRI on my spine. Are there any Problems or Precautions that I should be aware of??? Product Code is PS1535X2.....I can find no info on it and the implanting Physician is long retired.
Larry, Missouri, USA, December 12, 2013
SuzyQ - The BX Sonic is basically the bare metal version of the Cypher stent. MRISafety gives it a "conditional5" rating for Tesla strength 3.0.
Angioplasty.Org Staff, Angioplasty.Org, November 10, 2013 |
What tesla strength is approved for a Cordis BX Sonic Balloon-Expandable Stent from 2002? I have not been able to find information specific to this stent on the MRISafety website. I do believe it is a bare metal stent. Thank you
SuzyQ, California, USA, October 26, 2013
I am a neurosurgery resident of Bsmmu Bangladesh. I've a patient of suspected spinal pathology with a history of coronary stenting(2) in 2006. But the brand of stent & MRI compatibility of the stent is not known. We want to do MRI of whole spine. What can we do now?
BSMMU, Dhaka, Bangladesh, August 24, 2013
mrichic in Georgia - if you look at the MRI Safety database, compiled by Dr. Frank Shellock, you'll see that different stents have different tolerances vis-a-vis MRI. Mostly the older generation, which tend to have a greater amount of metal, need a lower Tesla strength scan. If the patient does not have a card, it may be possible to make an educated guess by getting a date for the stent placement. For the U.S., prior to 2003, stents were bare metal. From 2003-2008, stents were 1st generation drug-eluting stents, most likely Taxus or Cypher. From 2008 to the present, the 2nd generation stents were available, either Promus, Xience, Taxus Liberte, Endeavor, or Resolute.
Angioplasty.Org Staff, Angioplasty.Org, August 10, 2013 |
As an MRI tech, I was wondering about scanning patients with heart stents with no info cards. In reading this forum, I feel that is info is vital and a patient should not be scanned till stent is identified. Would this be an accurate assumption on my part?
mrichic, Tifton, Georgia, USA, August 8, 2013
Massachusetts - This topic is about MRI and stents. You don't mention if you have a stent but your post sounds like you are having problems outside this topic area. You should discuss the adverse effects you're experiencing with your doctor.
Angioplasty.Org Staff, Angioplasty.Org, April 16, 2013 |
hi I think you are my last hope. I had an MRI on Wednesday 3/27/13 for my shoulder. I had bin taking medications for week before list ( 65 mg iron 325 mg ferrous sulfate) and (ic naproxen 500mg ) and (ic cyclobenzaprine 10 mg ) and ( tramadol hcl 50 mg ) and (ic omeprazole dr 20mg ) and (ic atorvastatin 80 mg) and (nitrostat 0.3 mg mix) resulting impacted stool . I weight 200lbs the MRI was for my shoulder they wrap a strap around my waist to hold square lead to my shoulder and put towels on my side so wouldn't get burned and put me in the tube I may have crossed my legs when the machine went on I felt intense heat in my belly area and eyes pressed button to get out. I told them what I felt. the said they didn't know what I meant . its gotten worse my vision changed and I cant eat or drink and have terrible gas pains they think I'm nuts . I think I had internal (rf) heating from the crossed legs and the meds with the iron . I also had a nessin surgery in 1993 is this possible? I was fine till I had the MRI can you find out and help me i have since spent five days in the hospital with no answers they say an MRI cant hurt you I'm still the sick and now have a had time seeing PC screen
there is always a first time, Massachusetts, USA, April 12, 2013
Marc F. from Nevada -- Are the stents near your lower back. If so, you need to find out the brand and model of the stents and then look it up on the database we've referenced below
Angioplasty.Org Staff, Angioplasty.Org, February 6, 2013 |
I had 2 arterial stents put in but not against or in the heart. That was 4 days ago and l may have another MRI on my lower back ordered before the stent by my neurosurgeon. Thoughts please.
Marc F., Sparks, Nevada, USA, February 6, 2013
JoAnn B in Florida -- According to the MRI Safety database, compiled by Dr. Frank Shellock, your stents are MRI safe at a field strength of 1.5-Tesla.
And Shailesh in New Delhi -- Your relative's stent is probably a "Bard XT" and, according to Dr. Shellock's database, it is also safe at a Tesla strength of 1.5
Angioplasty.Org Staff, Angioplasty.Org, February 3, 2013 |
I have two stent implants they were put in on 6/5/97 PALMAZ-SCHATZ STENTS. product code PS 1530 lot number 131321 & 131325 site of implants R.C.A. is it safe to have an MRI?
JoAnn B., Wellington, Florida, USA, January 29, 2013
Dear Sir , My Brother in-law had gone Angioplasty in June 1997 and as per records 3 stents were putted of BART-XT make as per record . Now he is suffering from Sciatica Pain and doctor had asked for MRI for proper diagnosis . Some doctors are saying it is possible and some are saying not possible. Please guide me.
Shailesh B., New Delhi, India, January 28, 2013
Ron in Michigan -- It would be extremely helpful if your doctor could tell you the brand of the stent, but also exactly what type of device it is. A "shoulder" stent is probably a subclavian stent. Can't believe there is no record of which stent. There has to be some indication in the hospital records. In any case, discuss this with the MRI tech and have them use as low strength a magnet as is feasible.
Angioplasty.Org Staff, Angioplasty.Org, Jan 9, 2013 |
I have a stent in my left shoulder need to have MRI of my brain. The Dr. that put in stent has no records on the type of stent he used . What do I do so I can get the MRI?
Ron, Michigan, USA, January 8, 2013
PM from Georgia -- Thanks for the info. Many of the most recently approved coronary stents have been approved for immediate MRI -- but, of course, you should check with the manufacturer -- there are instances when an MRI is necessary and can't wait for 8 weeks. We reported on this back in 2005, and since then most coronary stents have gotten approval for immediate MRI.
And Peggy in Arizona, not sure what the tech meant by "6". Strength of MRI is measured by the magnet, usually a 1.5 or 3.0 Tesla.
Angioplasty.Org Staff, Angioplasty.Org, Decmebr 29, 2012 |
The general rule of thumb is wait 8 weeks post stent placement and scar tissue will form around stent, preventing it from "possibly" moving. We routinely scan stents after 8 weeks. After 25 years working in MRI, I have never encountered a problem with a patient. We have a 1.5T magnet.
PM, Columbus, Georgia, USA, December 27, 2012
I had two stents in the past year. A third one in 1999. Two days ago I had an MRI of my back. Tonight my heart beat is irregular and a skin problem on my lower back. I was in the MRI approx. 40 min. They were concerned about doing the MRI due to the old 1999 stent, which we did not know what is was made of. But they did it anyway based on the MRI tech stating it would be OK since he was doing a low energy of 6....whatever that is. At least this is what I heard, a measurement of 6 and under is safe, the tech said. Does this sound OK to you? Could the irregular beat be due to the MRI magnetic imaging....no dye in veins.
Peggy J. D'Amato, Scottsdale, Arizona, USA, December 13, 2012
My brother who had a history of neurological problem and suffering from acute pain on the nerves of left leg developed cardiac problem and had to undergo angioplasty. Subsequently, as his pain on the left leg got increased, advised to go for an MRI for evaluation. Please advise whether it will be safe to go for an MRI immediately after angioplasty, if not to what time one has to wait for an MRI after placing a stent
prabhatham vayanasala, District Hospital, Palakkad (Retired), India, December 7, 2012
To paleryder. When timing is limited to 15min this refers to the actual sequence not the total scan time. There is no single sequence that would exceed 15min when scanning the spine on any MRI machine. The MRI would have not caused any issues with your stents if they are compatible - and obviously this was mentioned as the techs discussed scan conditions. It is normal in MRI to experience some heating and this to is limited and monitored automatically by the machine and remains within FDA limits. Your Dr who asked for the test has to also consider the risks of MRI. Disappointing you had a negative feeling about your study and named a department without fully understanding the physics and issues associated with MRI. Other readers should feel comfortable in that any implant is scrutinised before their scan - this is policy.
Common sense, Sydney, NSW, Australia, October 19, 2012
To all posters -- read through our responses to these types of questions. We'd refer all to the database at MRISafety.com where you can look up your device and see what's known about it. If you have further questions, or your device is not listed, ask your interventional cardiologist, the physician who placed the stent. Hint: when you do a search on MRISafety, use the category "Coils, filters, stents and grafts."
Angioplasty.Org Staff, Angioplasty.Org, October 18, 2012 |
I need an MRI but I have 2 stents in my heart. What do I do I received a card when I had it done that It is stainless steel and I should not have MRI. Is there anything else I can do beside MRI to see what is wrong with me?
cchimblo, Fairfield County, New Jersey, USA, October 17, 2012
HELP! I believe my life was just endangered--I have FIVE coronary artery stents--placed in MID RCA and adjacent artery in 2010. I am NOT on Plavix at this time-was told type of stents used I can stop after 22 months--I also was told I can have MRI--but NO continuous scanning more than 20 minutes. Also doctor prefers a 1.5 over 3 Tesla. I had MRI of back today--the tech PROMISED to take me out of the machine after 16 minutes--and then put me back in to finish the test. he said 'we have scanned patients in the 3 attenuation it really doesn't matter with modern stents" i said--ok-but remove me after 16 minutes. he said he would...They DID NOT--I was in there 30 minutes maybe 35 and when I was pulled out-a different person was there not the tech I saw--she said "you were only in 15 minutes" I said -NO i know how to tell time--it was 30 minutes--my chest is warm--she refused to give me her name--badge turned around IN THE HOPSITAL--this is MOUNT SINAI NYC--am I in serious danger now? what do I do? They did NOt do as they promised me. I just got home. I have chest pain..but I have had chest pain prior to test on and off. Worried the MRI caused damage--it was 3 atenuation for 30 minutes.
paleryder, New York, New York, USA, August 23, 2012
I have 10 stents, 6 in heart and four in groin area. Some are double stents. My vascular doctor wants a MRI done at the highest T level and my cardiologist agrees. The Radiologist wants me to sign a waiver, do you think the highest MRI is necessary to find out where my blockages is occurring since I am having circulation issues? I also had thrombolysis of the right iliac artery, then later the left. Can just a normal level MRI be sufficient?
RjCollin, Chicago, Illinois, USA, May 21, 2012
Cos from the UK -- If you look at our post from August 2010 (and any since then), you will note that we are not saying the Tesla strength of an MRI can be adjusted. However, some facilities have more than one MRI unit, and some older stents are not cleared definiteively for a full 3.0T so a lower strength machine should be utilized in those cases. Also patients with multiple stents may need special consideration.
Angioplasty.Org Staff, Angioplasty.Org, March 1, 2012 |
Please Please stop saying the TESLA strength can be adjusted. It CAN'T full stop. Not possible. 1.5 tesla is and always will be a 1.5 tesla and the same applies to a 3 Tesla. Most if not ALL coronary artery stents are safe up to 3 Tesla. Scan away no problems!!!
Cos, Spire, UK, February 29, 2012
To all readers -- see our March 28 post. Most stents are okay for MRI, but it is important not to go beyond the recommended Tesla strength, Make sure the MRI technician is aware of the fact that you have a stent. And refer to the database we linked to.
Angioplasty.Org Staff, Angioplasty.Org, November 11, 2011 |
Had a 3*38 Xience LL drug eluting stent in July 2011. I would like to have a brain MRI but I am not sure how safe it is. Would you please help?
Gordon, UK, November 10, 2011
I've had three stents placed between 2007-2008. First stent was unmedicated the second was. The third however was inserted into the first stent. It is longer and larger diameter. I have had low level MRI with no problems,however,they would not do a high level MRI because they were not sure what would happen with the doubled up stent. Just wondering if you are aware of any problems that could occur using the higher strength MRI?
Ray W, Ontario, Canada, September 5, 2011
Very Worried in North Dakota -- If you read our March 28 post, you'll find a
database of stents and whether or not they've been tested to be safe for
MRI and, if so, at what strength Tesla they've been measured. However, since
you have ten stents, the chances are that you have a number of different
types.
If
your
MRI technicians
were
aware
of the
situation,
you should be okay, because hopefully they would have given you an MRI of
a low enough strength. Do you know what Tesla strength MRI you got? Sick
to your stomach is not a symptom
we have heard of associated with any problem caused by the MRI
heating up or moving the stents, but discuss this with your cardiologist,
if only to calm your worries.
Angioplasty.Org Staff, Angioplasty.Org, August 21, 2011 |
I have 10 stents and just had an MRI. They
told me it was safe but now I feel very sick to my stomach and I'm very
worried.
Very Worried, Watford City, North Dakota, USA, August 20, 2011
I had a bare metal 4.0 stent put in my coronary
LAD in 2001. In 2006 or 2007 I had a brain MRI performed and experienced
sharp localized chest pain which
increased in intensity during the MRI to the point where, for the last several
minutes, I was on the ragged edge of aborting the procedure. As soon as the
MRI ended the pain was gone. No other apparent effects. I do not plan
to do one again.
Dave, Texas, USA, July 19, 2011
I am getting ready to have heart cath.
they said may need a stent. I have many other health problems and have
MRI and CTs frequently I joke that I glow are there other sites to
show what this site is showing? Has anyone been able to sue when the
MRI moves
their stent? I mom thought her's moved but she wasn't sure she didn't
think they could. Looking for other ideas than stents if one needed
such a thing a I do spend a lot of time in MRIs.

My brother is currently in hospital with
two clots in the neck, possible stroke. He has a stent put in India but
lives in Africa and has lost medical
records His African drs are asking for stent information for MRI purpose. What
does one do in a situation if you don't know the information about the stent?
Thanks.
Sister, USA, May 17, 2011
Has anyone considered making stents out
of a non-magnetic metal (such as aluminum)? Is that possible and would
an aluminum
implant cause a problem with an MRI?
Bill in CT, Orange, Connecticut, USA, March 29, 2011
Joel
Z from Chicago -- If you search
Dr. Frank Shellock's database, noted in our August 16 and
January 27 posts, you find that the Palmaz-Schatz stents are considered "SAFE" for
MRI when the field
strength of the unit is 1.5 Tesla. This is very important, because greater
Tesla fields (for example, 3.0) may not be. The referenced article
appeared in the October 1998 of the Journal
of Invasive Cardiology,
and is titled "Are
Current Cardiovascular Stents MRI Safe?" (pubmed: http://www.ncbi.nlm.nih.gov/pubmed/10762825).
Angioplasty.Org Staff, Angioplasty.Org, March 28, 2011 |
Is the 1996 Palmaz-Schatz expandable balloon
stent compatible to do an MRI? My 83 year old mother had the stent implanted
in 1996 and is supposed to have an MRI tomorrow. However, neither the MD's
nor us can seem to find any info whether it is safe to do an MRI with this
stent. Thank you for any help you can
give us.
joel z, Chicago, Illinois, USA, March 28, 2011
MRI-Stent from
India, and other readers-- read the response below from August 16 -- when
getting an MRI, all stent patients
should inform
the
doctors and technicians that they have a stent, and what brand it is,
so to be sure that the MRI is not so strong as to disturb the stent.
Can you
find out from the hospital what strength Tesla the MRI that you had was??
If you know the brand of stent, you can search "The
List" on the web site to www.mrisafety.com to
see if your stent is safe and for what strength
Tesla.

Endeavor 3.5*18 stent ptca to lad- now i have undergone MRI for limber
i feel MRI has disturbed the displacement of stent daily after MRI i
am experiencing some change in chest? why this is? i am unable to explain
but there is change? is it possible my stent is disturbed from where
it is placed?

I had stent on sep 30th 2010 one in my right coronary
artery, I lost my vision after angioplasty,The consultant referred for
MRI of Brain and Optic region.
But the MRI Department refused to take the MRI. I am helpless my vision is still
bad with Hessy, Diplopia. Can any one help to answer whether I am eligible for
MRI.

In August 2004, I had one cypher and one
Taxus DES stent placed. In december 2004, I had 2 more Cypher (Cordis)
DES stents placed. (feel I did not need these) My Heart enzymes elevated
drastically the night of the 12/2004 stenting. They did an MRI of the
heart. No one told me about the dangers of this. 3 months later I had
an acute Coronary event. Another Cypher was placed next to a previous
cypher in the LAD. All this happened at one of the top 10 heart centers
in the country. Switched heart centers and learned......Now need an
MRI of the ankle. Good hospital alerted me to the potential hazards of
5
heart stents. I was advised to call Cypher Mfg. They told me that since
I had more than 2 stents it was not advisable to have the MRI. They
warned me of the possibility of malpositioning. I will
live
with the bad ankle.

Concerned Tech and NancyD
-- Thanks to all for your comments and yes...to clarify, the Tesla
strength of an MRI scanner
cannot be adjusted
per se, although Philips Medical Systems makes a scanner that can be
configured to use different strength fields -- but it is not adjustable
via a dial
or similar controller -- it can only operate at one strength per configuration.
If a patient needs an MRI and their stent is not "SAFE" for
an MRI done at 3.0 Tesla, then they need to be scanned by a lower strength
unit, possibly
at the same hospital/facility or, if there is not one on the premises,
at a different facility. And thanks NancyD(!!) for your very clear
explanation and also for the link to www.mrisafety.com.
We also were referred to this site by John LaMarche, the Clinical
Marketing Manager for MR at Toshiba Medical Systems. Patients and healthcare
professionals
can search "The
List" on this site and see information
about their device. It's also important to read through the site's Disclaimer.
The site was created and is maintained by physiologist Frank G. Shellock,
Ph.D.
as a service to the profession. Angioplasty.Org hopes to feature
an article about Dr. Shellock and the site in the near future.
Angioplasty.Org Staff, Angioplasty.Org, August 16, 2010
I am the MRI safety officer
at my hospital. I will try to explain why MRI facilities need the information
on stents (and
ALL metallic items implanted in your body). Implants that are tested
are rated as SAFE, CONDITIONAL or UNSAFE. Safe means we can scan immediately
with no conditions, conditional means we have to stay within certain
limits
set by the manufacturer when we scan. Unsafe is unsafe, period. A large
percentage of implants are rated as conditional. THAT is why we need
the make/model # of the implant. In addition, not all implants have been
tested
and those that have been may not have been tested at the higher tesla
field strengths now in use. And no, the tesla CANNOT be adjusted on an
MRI machine,
BUT, you can be sent to a lower tesla machine if needed. Also, not all
implants or stents have been tested as many are being added to the marketplace
daily. That being said, if we cannot get the information we need, a radiologist
can make the decision that the need for the MRI outweighs the risk. More
information can be found on www.mrisafety.com.
This site is used by MRI facilities for the
exact purpose of identifying safety of implants.

Concerned MRI Technologist, Melbourne Australia, August 12, 2010
Can anyone answer this question -- are there
any coronary stents unsafe
for
a 1.5 T MRI ?
S CONAT, olympic medical center, Port Angeles, Washington, USA, July 23,
2010
To all -- many stents have been approved by the
FDA for MRI imaging. But if there are any questions about your stent in
particular, you should contact the manufacturer of the stent. Before 2003,
all stents would be bare metal. To Lev, the multilink stent was made by
Guidant, now Abbott Vascular. To Patel, GE should be addressing these issues
with your lab. It's hard to believe that you are unable to adjust the Tesla
strength of your MRI. And Mimi42 -- the hospital hwere the stent was placed
MUST have the information. It would most likely be a Palmaz-Schatz or similar
stent (manufactured by Cordis/J&J).
Angioplasty.Org Staff, Angioplasty.Org, July 16, 2010
My husband had at least one stent implanted around
1993 and in 1996 had CABG following restenosis of the stent. He now needs
an MRI of the Cervical Spine. The Radiology center won't do it without
information about the brand of the stent. We can't get that information
at this point. Would it be dangerous to reply "no" to the question of whether
or not he has a stent?

We upgraded our GE scanner recently . The gradients
are stronger than before and cannot be adjusted . So we have not been able
to scan patients who had cardiac stents. Ironically we were able to do
so in past . that has created a nightmare for doctors and patients trying
to schedule. May be someone would
guide us??

LucianF -- If the stent was placed in 2000, it
would be a bare metal type, not a drug-eluting or "medicated" stent
which weren't marketed until 2003. There should be a brand name or model
-- one
star or three star don't ring a bell. We'd strongly suggest calling Boston
Scientific Patient Services at 1.866.484.3268 for
specific assistance on this issue. Also definitely tell the
technicians
doing the MRI about the stent -- they can adjust the Tesla strength for
safety.

My father had a stent placed in 2000 and needs
an MRI of the lumbar spine now. The only information on the stent that
we have it that it was manufactured by Boston Scientific and it is either
a "one star" or "three star". We don't know if it was medicated or not.
Would it be safe to have the MRI. Thank you
for your answer.

Legacy stents such as the Palmaz-Schatz and AVE
have most likely not been testing specifically for MRI safety, although
more recent stents with virtually the same metallic composition have
been. It is also important that the MRI technician knows you have a stent,
so
that the strength of the MRI can be adjusted for maximum safety. We would
recommend contacting the manufacturer about a specific stent in question.

I have a 3.0 Palmaz-Schatz Stent placed in 1996.
Is it safe to have an MRI? If not, is there an alternative to MRI that
is safe?

I have an AVE stent #AVE DGFW3530. I understand
AVE has been bought out by Medtronic and all the part numbers have changed.
It was implanted 7/15/98,
making it over 10 years old. I am having back problems now and really need
an MRI, but my surgeon will not order a MRI unless he has assurance this
older stent
is truly MRI safe. Can anyone from Medtronic or someone who really knows respond
and let us know if this is safe? Please help! Thank you very much
