What is an arthrogram?

An arthrogram is a medical imaging procedure that uses X-rays or magnetic resonance imaging (MRI) to visualize the inside of a joint, such as the shoulder, hip, or knee.

During an arthrogram, a contrast dye is injected into the joint to make the structures inside the joint more visible on the imaging scans. This allows doctors to better evaluate the joint for any abnormalities, such as tears in the cartilage, ligaments, or tendons.

Arthrograms are commonly used to diagnose joint conditions, such as arthritis, torn rotator cuff, or meniscus tears. They are also used to guide procedures like joint injections, aspirations, or surgeries.

Arthrograms are generally safe procedures, but some potential risks include allergic reactions to the contrast dye, infection at the injection site, or injury to the joint structures.

Before undergoing an arthrogram, patients may be advised to avoid eating or drinking for a certain period of time and to inform their healthcare provider of any allergies or medical conditions they may have. After the procedure, patients may experience some soreness or swelling at the injection site, but this is usually mild and temporary.
