MRI
Magnetic resonance imaging (MRI), one of the most dramatic advances in diagnostic technology, provides an unparalleled view inside the human body. MRI uses no X-rays. Instead, a computer creates detailed tissue "slice" images from data generated by a powerful magnetic field and radio waves. The computer creates 3-D images that can be viewed from any angle.
Because certain medical devices can be affected by the magnet, patients with pacemakers, defibrillators and some other implanted devices are excluded form undergoing MRI exams.
MRI is used extensively to diagnose injuries and conditions related to the brain, neck, spinal cord and soft tissues. It is also especially useful for evaluating medical conditions involving joints, muscles and bones.
MRI technology is also capable of imaging flowing blood in virtually any part of the body. This allows technicians to perform studies that show the arterial system in the body, but not the surrounding tissue. In many cases, the MRI system can do this without a contrast injection, as is required in vascular radiology. To enhance certain other types of diagnostic studies, however, a contrast medium may be injected into a vein.
The Yuma Radiology Department provides a full spectrum of patient imaging using traditional MRI equipment. MRI scans are offered for both inpatient and outpatients five-days-a-week. All of Yuma’s MRI technologists are credentialed by the American Registry of Radiologic Technologists.
During your exam — which may take 15 minutes to an hour — you lie on a movable table inside the scanner. Exams may be noisy, so you may be given earplugs or headphones with music. Patients utilizing the traditional MRI scanner sometimes experience claustrophobia. Medications are available to help.
