Magnetic Resonance Imaging
(MRI or MR)
Magnetic Resonance Imaging (MRI or MR) is among the safest and most comfortable medical imaging procedures available.
MRI can image virtually any part of the body, including the brain, spine, internal organs, muscle groups, tendons and ligaments, bones, central nervous system, and flowing blood in virtually any part of the body to distinguish possible areas of concern
MRI is Ideal for:
- Diagnosing multiple sclerosis (MS)
- Diagnosing tumors of the brain
- Diagnosing strokes in their earliest stages
- Diagnosing infections in the brain, spine, abdomen or joints
- Diagnosing tendonitis
- Visualizing torn ligaments in the wrist, knee and ankle, shoulder, and elbow
- Evaluating masses in the soft tissues of the body, abdomen, or pelvis
- Evaluating bone tumors, cysts and bulging or herniated discs in the spine
- Evaluating the arteries and veins throughout the body
How does MRI work?
Utilizing a powerful magnet in conjunction with radio waves to cause tissues in the body to take on specific appearances, MRI allows the radiologist to isolate specific areas or systems for analysis and comparison to healthy tissue. MRI essentially takes slices like slicing a loaf of bread, in any direction, (top-bottom/ side-to side, or front to back).
How Our MRI Technology is different
Star MRI of Wayne has installed the region’s first Open Bore, 1.5 Tesla, magnetic resonance imaging (MRI) system that combines a larger bore, or opening, for obese and claustrophobic patients with the ability to capture high-field quality diagnostic images.
“This is going to increase our efficiency and patient convenience,” says Michael Dwyre, Owner. “The patient-friendly design of this magnet will make it easier for large patients and those with claustrophobia to have a MRI examination which produces higher quality images. This will potentially reduce the need to repeat and interrupt exams.”
“Certainly, all patients deserve the same access to innovative medical imaging technology used for visualization, diagnosis and treatment planning of cancer, diabetes, heart and vascular disorders and other diseases associated with obesity,” says Jeffery Bundy, president of the MR Division of Siemens Medical Solutions.
Since two-thirds of American adults are overweight, the health-care industry is challenged to accommodate these larger patients with imaging systems that were designed for people who weigh much less. Currently, patients too large to fit inside the bore of a high-field MRI magnet have image studies done in open MRI systems with low-field magnets. This limits the diagnostic usefulness of the images obtained. The field strength of a magnet is measured in units of Tesla – the higher the number, the higher the field strength. The higher the field strength, the better the quality of images produced.
The Siemens Medical Solutions MAGNETOM Espree installed at Star features a bore opening of nearly 2.3 feet in diameter and almost one foot of free space between a patient’s head and the magnet. The Espree also features the shortest 1.5 Tesla magnet available. Approximately four feet long, the magnet allows more than 60 percent of exams to be completed with the patient’s head outside the bore, helping to ease claustrophobia.
The new system provides up to four times more signal-to-noise ratio over traditional open MR designs, which is desirable in imaging larger patients. In addition, the Espree can perform advanced clinical applications in less time, because it combines strong gradient performance with Siemens’ Total imaging matrix (Tim™) technology. Tim is the first whole body surface coil design that enables the highest resolution images in a shorter acquisition time. Tim coils are very light, making them both easy to position and tolerate when scanning larger patients, improving cooperation.
The MAGNETOM Espree provides best patient comfort and high-quality images and diagnostic confidence for all types of patients.
Advanced TIM technology
With TIM (Total Imaging Matrix), MAGNETOM Espree offers superb imaging performance. Patients benefit from more flexibility, accuracy, speed, and diagnostic confidence.
TIM’s integrated coil technology means the patients will only have to enter the scanner one time to perform an entire Head/Neck/Spine combination. The scanner will step down and automatically compose the sagittal images for review. Faster scanning means patients will need to hold still for a shorter amount of time and spend less time overall on the scanner for excellent image quality and total comfort.
- Exceptional image quality
- Faster acquisition and exam time
- Increased patient comfort with the combination of 125cm ultra-short system length with 70cm Open Bore
- Expanding care to a wider range of patients (e.g. claustrophobic or obese patients 550 lb weight limit)
- Broadening clinical possibilities (e.g. interventional MRI or kinematic studies)
Trendsetting in patient comfort
With MAGNETOM Espree, you and your patients – can change the way you think about open MRI. The 70 cm inner diameter makes CT-like comfort possible. And, the scanner is remarkably short with 125 cm that enables head-out or feet-first for most exams.
What Do I Have to Do?
During the MRI, patients are required to remain still during each imaging sequence, which may last 2 to 6 minutes or a total exam time of 20 to 45 minutes. This is a non-invasive procedure so patients can relax and often nap during these tests.
Star MRI of Wayne is designed with patient comfort in mind; patients may relax and listen to their favorite radio station while undergoing their exams. Our accredited, highly trained technologists will make every effort to make even the most anxious patient comfortable.
MRI is not for everyone
Patients who have the following may not be able to have a MRI test:
- Pacemakers/defibrillators or pacing wires
- Metal fragments in one or both eyes
- Inner ear implant
- Spinal stimulators or Brain Stimulators
- Brain Aneurysm Clips (the newer aneurysm clips may be MRI compatible. Your surgeon should be able to provide any documentation regarding the composition of the clip)
MRI Pre-procedure Checklist
There is no special preparation for most MRI exams. We encourage our patients to wear comfortable clothing such as a sweat-suit without metal snaps for zippers. As a courtesy to our patients we can offer robes to wear if needed.
For our patient's safety, we ask patients to remove all hairpins, body piercings, watches, and most jewelry before entering the MRI scan room. It is best to leave your valuables at home. If you are going to have an MRI of the abdomen do not eat 3 hours prior to your exam.
