Magnetic Resonance Imaging (MRI)
What is an MRI?
MRI stands for Magnetic Resonance Imaging - one of the most advanced methods of diagnostic examinations available. It does not use X-rays or radiation. Instead, MRI uses a magnetic field and radio waves to produce high quality images of the inside of your body. Powerful computers reassemble the MRI signal into a set of pictures that will be reviewed by a physician.
MRI is a safe, painless examination that has no known side effects. You and your doctor will use your MRI scan results to plan your course of treatment.
Magnetic Resonance Imaging (MRI) is one of the most advanced imaging tools available today. MRI is commonly used to view the brain, spinal cord, bone and joints – as well as other body parts.
MidMichigan offers some of the most advanced MRI technology available, including:
- 1.5 Tesla Wide Bore MRI - This technology is the first-ever digital broadband MRI scanner that delivers superb image resolution, fast exams and a more open patient experience. The wide-bore makes patients less confined, in fact, most scans can be done with the patient's head completely out of the system. The powerful 1.5T magnet provides detailed images for enhanced diagnostic confidence.
- 3.0 Tesla MRI - This technology provides the highest resolution and greatest diagnostic capabilities of any MRI available today, while providing greater patient comfort than was previously available in a closed MRI. Available at MidMichigan Medical Center - Midland.
Preparing for Your MRI
Your appointment will be scheduled at the location that is most convenient for you and that offers the type of MRI technology your doctor recommends. An open MRI unit is available for patients who are uncomfortable in closed spaces. Let your doctor know if you experience claustrophobia or discomfort in tight spaces.
Staff will contact you a few days prior to your exam to confirm your appointment, answer any questions you may have, notify you of the time you should arrive and determine that you can safely be scanned by MRI.

What You Can Expect During Your Scan
Before the scan, your technologist will explain the procedure and answer any questions you may have. They will then help you onto the scanning table and make you comfortable. Depending on the part of the body being scanned, you may receive an injection of a contrast agent (or special dye) that will make some of your body tissues easier to see. Sometimes a special antenna will be placed around a part of your body.
The table will then slide very smoothly into the opening of the MRI unit. You won’t feel a thing, but you may hear a bumping noise and the hum of the machine. This is normal. A microphone and speaker are installed inside the magnet to allow you to talk with the technologist during the procedure. If you have any concerns during your MRI scan, please speak up. The technologist will also be able to see you through a glass window.
After Your Scan
When the exam is completed, You may dress and go home. A board certified radiologist will carefully review and interpret your scan. The results will be sent to your doctor within a few days. Please make an appointment with your doctor to discuss the results.
