MR Arthrography

MR arthrography is most commonly utilized in the shoulder when optimal visualization of the glenoid labrum or undersurface of the rotator cuff is needed.  A mixture containing dilute Gadolinium contrast is injected into the glenohumeral joint to distend the joint capsule and separate internal structures for optimal assessment on subsequent MR imaging. The mixture also contains iodinated contrast allowing visualization during fluoroscopic injection and acquisition of a standard radiographic arthrogram study prior to MR imaging.

We also frequently perform elbow MR arthrography, allowing us to detect loose bodies or clinically-significant partial thickness ulnar collateral ligament tears in professional athletes with medial elbow pain.

MR arthrography is also occasionally performed in the wrist for better characterization of triangular fibrocartilage injury, in the hip for identification of acetabular labrum tears, in the knee, for assessment of articular cartilage abnormalities or recurrent meniscus tears, and in the ankle for detection of loose bodies or chondral defects.

Therapeutic Injection of anesthetics can also be performed at the time of arthrographic contrast injection.
