Important information to know
Doctors use magnetic resonance imaging (MRI) to find diseases or abnormalities in the body without using X-rays. MRI uses a magnetic field and radio waves to create detailed images of the body. MRI is non-invasive and painless and most scans generally take 20-60 minutes, depending on the type of exam your doctor has ordered.
During an MRI scan, you lie on a cushioned table that moves into the scanner. An injected contrast agent may be used. MRI contrast agents rarely cause allergic reactions.
The technologists stays in contact with you throughout the exam. When the scan begins, you will hear a muffled sound for several minutes. Lie as still as possible, as any movement during this time can distort the image.
