MRI (magnetic resonance imaging) is a diagnostic procedure that combines
a powerful magnet, radio waves and computer technology to provide detailed
images of tissues, muscles, nerves and bones. Because MRI uses magnetic
force and radio waves to create images, there is no radiation exposure
during the procedure. MRI is often used instead of CT to study soft tissues
or organs because bones do not obscure the organs and soft tissues as
they do with CT imaging.
Advanced technology and imaging capability
MRI can be used to assess everything from ruptured discs in the spine to
detecting brain tumors and vascular diseases through techniques such as:
Breast MRI can be a more effective imaging technique than mammography for some women,
and can provide additional details for diagnosing and evaluating breast
Spectroscopy (MRS) assesses chemical abnormalities in the brain for conditions such
as coma, Alzheimer's disease, stroke, brain tumors, head injury and MS.
Angiography (MRA) evaluates blood flow, or detects brain aneurysms or blood vessel
abnormalities. It is used to visualize renal, carotid and vertebral arteries,
or examine the aorta for aneurysm.
Perfusion and diffusion scanning examines blood flow through tissues to evaluate strokes.
Enhanced patient comfort with open MRI technology
At Dallas Regional Medical Center, patients can receive top-quality MRI
scans without being enclosed in a traditional MRI tunnel. The Hitachi
Oasis™ 1.2T scanner has an open design that allows you to see your
surroundings and even have a loved one nearby during the procedure. For
anyone who has felt anxious or uncomfortable during a traditional MRI
exam, this state-of-the-art technology offers a more comfortable alternative.
