July 3, 2007 -- Platte
Valley Medical Center’s new Medical Imaging
Department will offer one of the highest combined levels of MRI
(magnetic resonance imaging) and CT (computed
tomography) imaging in the world with new features that enhance both patient
comfort and image accuracy.
Imaging is a key diagnostic tool available to physicians.Platte Valley Medical
Center is the first hospital in the U.S. – in fact, the first outside of Japan
- to install a Toshiba Vantage MRI with Atlas upgrade.The system provides the
latest magnetic resonance imaging capability available in the U.S. today.
The new system was first introduced last December at a conference of the Radiological
Society of North America.At the leading edge of MRI technology, the Vantage with
Atlas system produces the best image quality available within the most patient-friendly
environment.
With its new MRI technology, Platte Valley Medical Center will serve as a showcase
for Toshiba with health care professionals from throughout the nation flying
into Denver International Airport to preview the new technology in Brighton.
Patient-Friendly MRI
The new MRI system minimizes the two most negative experiences patients traditionally
have with the MRI imaging process - claustrophobia and the heavy clanging and
buzzing noises loud enough to require use of special ear plugs.
It offers patient-friendly features such as a shorter magnet and ultra short
bore platform - more donut-shaped than tube-shaped - minimizing the claustrophobic
effect of being inserted into a narrow, long tunnel.For most procedures, the
patient enters the magnet feet-first, rather than headfirst, and unless a diagnosis
requires imaging of the head and shoulders, those body parts remain outside the
magnet to greatly increase patient comfort.
In addition, the system features patented noise reduction technology that effectively
reduces noise during operation by up to 90 percent compared with older MRI systems.This
feature led the American Tinnitus Association to recommend Toshiba to its members
who have auditory sensitivities.
“Over the years, patients have had concerns with claustrophobia and overall discomfort
during MRI scans.Now, we can alleviate many of these issues,” said Karen Swanson,
director of medical imaging for the hospital.“The short-bore design also makes
the system feel more open, and the Vantage has significantly reduced noise during
scanning which is more calming for the patient.
“When the patient is more at ease, we have greater success with the scan and
capture better images to help the physician make a confident diagnosis.”
Image Clarity
The new MRI scanner’s patented gradients, the “horsepower” of the system, increase
the clarity of images.The imaging process is faster because the integrated coil
system eliminates the need to move the patient in and out of the scanner to change
coils in order to complete various procedures.This allows for more images and
procedures within a given timeframe.
Using an advanced MRI technique, physicians can simultaneously view images of
vascular structures in the chest and abdomen without the use of contrast agents,
which also improves patient comfort, reduces cost and allows the scan to be performed
repeatedly, if needed.
In addition to its patient comfort features, the Vantage is a high-field MRI
system that performs a wide variety of MRI exams including the latest state-of-the-art
imaging techniques.For example, the system enables physicians to perform studies
including cardiac imaging, EPI functional perfusion, and magnetic resonance angiography
(MRA).
“As medical technology becomes more and more sophisticated,” Swanson said,“we
are able to image and evaluate more medical conditions at earlier stages than
ever before.With early diagnosis, we can more effectively plan for a successful
treatment.”
Breast MRI
The new MRI will be equipped with a breast coil that is significant in light
of two recent studies published by The New England Journal of Medicine. One study
reported that breast MRI is highly beneficial as a screening tool for women who
have an especially high risk of developing breast cancer.A guideline issued by
the American Cancer Society recommended that these women have an MRI with their
annual mammogram.A second study revealed that for women who were diagnosed with
cancer in one breast, MRI scans detected 90 percent of cancers in the opposite
breast that had been missed by other exams.
How MRI Works
MRI uses a powerful magnet approximately 7,000-times stronger than the magnetic
force of the earth.During an exam, the patient lies inside the donut-like opening
of the magnet.
MRI technology is used to identify tumor masses and other abnormalities in the
head, spine, chest, abdomen, pelvis and extremities, as well as to examine bone
and joint injuries.Frequently, this type of diagnostic information cannot be
acquired with any other medical procedure, except surgery.
64-Slice CT Scanner
The new PVMC hospital features one of the most sophisticated multislice CT scanning
technologies available.The Toshiba Aquilion 64 CT scan captures precise images
of any area of the body in as little as a ten second breath-hold .The fast scanning
capabilities offer significant benefits for a quick and accurate diagnosis of
trauma patients and patients experiencing chest pain or stroke.
In addition, exams, which take 10 to 20 minutes with a standard CT scanner, can
now be performed in just 19 seconds with images that allow physicians to see
internal injuries and disease in greater detail than ever before.
“The scanner is so fast that it can literally keep up with a beating heart,” said
Swanson.“For trauma patients the Aquilion 64 may prove to be lifesaving technology
by providing faster, more precise images of bones, organs and internal bleeding.”
“Physicians can see more anatomical information than previously was thought possible,” Swanson
added.“We can diagnose problems like blood clots, infections and cancer in greater
detail and with more clarity.We now have the ability to make an accurate diagnosis
at earlier stages, which means that patients can begin receiving treatment sooner
for potentially better outcomes.”
The system can be used to more accurately visualize soft plaque and measure coronary
stenosis for the detection of heart disease. Another benefit of the Aquilion
64 design is that its detector features a highly efficient ceramic material that
is able to reduce the overall radiation exposure to patients, as well as to hospital
staff.
While CT uses X-ray technology, it is distinguished from other diagnostic imaging
tools like traditional X-ray and MRI by its ability to display a combination
of soft tissue (like muscles, tissue, organs and fat), bones and blood vessels
all in a single image.Clinicians perform CT scans to diagnose kidney, lung, liver,
spine, blood diseases, cancer, tumors and cysts, as well as blood clots, hemorrhages
and infections.
The Aquilion 64 is designed to offer physicians greater diagnostic capabilities
by helping patients avoid more invasive medical procedures.The system delivers
unmatched multislice clinical images that capture up to 64 simultaneous anatomical
slices of 0.5 mm in a single gantry rotation.
As a result, Toshiba's multislice technology captures precise images of the body's
rapidly moving organs like the heart and lungs, which appear blurry when scanned
by a traditional CT.Multislice imaging also is especially useful for examining
patients who are unable to hold their breath, like trauma victims, acutely ill
patients and young children.
Other Imaging Enhancements
The new hospital will have several other enhancements in medical imaging:
-
The new department will be 100 percent digital, making all images accessible
by computer including mammography, nuclear medicine, X-ray, ultrasound, CT and
MRI.
- Two completely digital Xray rooms will be available, one in the medical
imaging department and one in the adjoining medical office building, cutting
exam times by 35 percent.
- A new nuclear medicine dual-head camera will reduce
scan time and improve image quality.
- A new Women’s Imaging Center will offer
bone density exams and breast imaging services (ultrasound and mammography).
