A magnetic resonance imaging scan is performed inside a large cylindrical magnet that has a patient table in the center. MRI uses a strong magnetic field and radio waves
to image the body. As there is a strong magnetic field, it is important to let the technologist know of any metal on or in your body.
Some MRI exams require an injection of an MRI contrast or dye. Typical MRI studies require 30 to 60 minutes. It is important not to move during the exam.
No special preparation is required for the exam. All MRI exams are interpreted by a board-certified radiologist with subspecialty training in MRI. It is commonly used to examine the brain, spine,
joints, abdomen and blood vessels.
