What is an MRI scan?
An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to view body structures.
When are MRI scans used?
An MRI scan can be used as an extremely accurate method of disease detection throughout the body. It provides valuable information on glands and organs as well as information on the structure on the joints, soft tissues, and bones of the body.
What are the risks of an MRI scan?
An MRI scan is a painless radiology technique that has the advantage of avoiding x-ray radiation exposure.
There are no known side effects of an MRI scan. The benefits of an MRI scan relate to its precise accuracy in detecting structural abnormalities of the body. Patients who have any metallic materials within the body must notify their physician prior to the examination or inform the MRI staff. All metallic objects worn on the body, such as jewelry or belts, must be removed prior to obtaining an MRI scan.
What can you expect during an MRI scan?
The technologist will simply ask you to lie down on a cushioned table, which will automatically move into the magnet after you have been comfortably positioned for scanning. The technologist will leave the magnet room, but will be in constant contact with you during the entire procedure. When the exam begins, you may hear a muffled thumping sound which might last a few minutes or several minutes. Just relax or take a nap, but always try to lie as still as possible since any movement during the scan will blur the pictures. If you are experiencing any anxiety, be assured that the technologist can hear and talk with you over an intercom. Headphones are available, and you can bring a CD or tape for your listening pleasure during your MRI scan.
How does a patient obtain the results of an MRI scan?
After the MRI scanning is complete, the computer generates visual images of the area of the body that was scanned. These images can be digitally transferred to a disc. A neuroradiologist will then interpret the images of the body. The interpretations are transmitted in the form of a report to the practitioner who requested the MRI scan. The patient will be contacted once the results have been reviewed.
