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. These images can be viewed from all directions and all planes.

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 Heartland Radiology Center provides a full spectrum of patient imaging using both traditional and open MRI. Emergency MRI scans are available 24-hours-a-day. Inpatient and outpatient procedures are available seven-days-a-week. All Heartland MRI technologists are certified by the American Registry of Radiologic Technologists and MRI registered.

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. Patients utilizing the traditional MRI scanner sometimes experience claustrophobia. Medications are available to help.

MRI is usually not appropriate for people with pacemakers or other implanted electrical devices because of the use of a strong magnetic field.
