MRI

mri at geisingerA magnetic resonance imaging (MRI) study is one of the newest and most powerful diagnostic imaging examinations available in modern radiology. Its clear images are particularly useful for viewing soft tissue, brain and spinal cord, joints, and the abdomen.

MRI does not use X-rays or other ionizing radiation. Instead, using strong magnets and radio waves, MRI can "see" into the body in any direction. Hydrogen atoms in the body react to the magnetic field and a computer analyzes the results and forms an image of the inside of the body.

An MRI is virtually painless, but may require an injection of contrast material. The images provide information about the structure and function of many different organ systems. An MRI is the test of choice for the central nervous system (brain and spinal cord), lower back pain (sciatica), and knee injuries. MRI can provide unique information about the musculoskeletal and cardiovascular systems, liver, reproductive organs, and soft tissue of the body. For most patients, an MRI examination is performed on an outpatient basis and is completely non-invasive, requiring only that the patient lie still for periods of between ten and fifteen minutes.

Procedure

If you have a pacemaker, aneurysm clips, prosthesis, or have ever had an incident in which you got metal or rust in your eye or anywhere else in your body, notify the doctor or a technologist BEFORE you have the MRI.

When you arrive for the MRI, you will meet a technologist who will help you during your visit and can answer any questions you may have. You will be asked to remove your watch, credit cards, coins, jewelry, and bobby pins that may be attracted to or affected by the magnetic field.

You will lie on a padded table for your MRI scan. The table will glide into a circular area where the magnet is housed. All you have to do is remain still and relax. You will not feel anything unusual. You will hear a banging sound. There is an intercom system so the technologist can see and hear you at all times. If you become uncomfortable, just say so, and someone will assist you immediately. Since there is no X-ray radiation used, visitors can sit in the scan room with you while you are having the procedure if they have no metal in their body.
