Your doctor has recommended you for an MRI of your shoulder. Magnetic resonance imaging (MRI) uses a magnetic field, radio waves and a computer to create detailed image slices (cross sections) of the shoulder. MR technology produces detailed images of the soft-tissue in your shoulder, and allows the physician to evaluate different types of body tissue (such as cartilage, ligaments and tendons) as well as distinguish normal, healthy tissue from diseased tissue. Our team of expert physicians, nurses and technologists is headed by Michael R. Terk, MD, Chief of Musculoskeletal Radiology.

If you are claustrophobic (fearful of small, enclosed areas) you need to discuss this with your physician before this exam. You doctor may prescribe a relaxant to help you through the exam. The imaging physicians at Cedars-Sinai will not prescribe such a medication for you.

We want to make your waiting time as pleasant as possible. Consider bringing your favorite magazine, book or music player to help you pass the time.

You may also bring a CD to listen to during the procedure.

Please leave your jewelry and valuables at home.

Please wear comfortable clothing.

You must tell the technologist, radiology nurse and/or imaging physician of any allergies you may have, and if you are pregnant or are nursing.

You will be asked to fill out a questionnaire which will determine if an MRI is safe for you. People with various implants (usually metallic) or with metal in their bodies (including some tattoos) may have difficulty with an MRI, which utilizes a strong magnetic field. The imaging physician needs to be informed of any of these potential problems.

You will lie on the scanning table head first with arms at your side.

Coils (special devices to improve image quality) will be placed around your shoulder.

The scanning table will slide your entire body into the magnet.

During the scan you will not feel anything, but will hear intermittent humming, thumping, clicking and knocking sounds. Earplugs will be provided to help mask the noise and allow you to hear music.

In some cases, the imaging physician requests a contrast agent (dye) to improve the quality of the images. The dye is injected into a vein in the arm, and may cause a cool sensation.

As pictures are taken you will need to hold very still.

The technologist is always able to see and hear you during the exam.

The exam will take approximately 45 to 60 minutes.

There are no restrictions placed upon you. You may eat or drive as normal.

Your films will be examined by an imaging physician and a report sent to your doctor. Your doctor will review the results with you.
