What it is (overview)

An MRI Upper Extremity Arthrogram is a specialized type of joint imaging test used to evaluate joints in the upper extremity—most commonly the shoulder, but also the elbow or wrist joint. It combines two steps: (1) a small amount of contrast material is placed directly into the joint space (the “arthrogram” part), and then (2) an MRI scan is performed (the “MRI” part). The contrast gently fills the joint and outlines internal structures, which helps the MRI show fine details that can be difficult to see on a standard MRI.

This test focuses on the soft tissues inside and around the joint, including cartilage, the labrum (in the shoulder), ligaments, tendons, and the joint capsule. It does not “measure” a number like a blood test; instead, it provides high-resolution images that help your clinician identify problems such as tears, inflammation, cartilage damage, joint instability, or scar tissue.

In plain language, results generally fall into a few categories:

• Normal/negative: The cartilage, labrum (if applicable), ligaments, and tendons look intact with no clear tear or significant inflammation. This can help rule out certain causes of shoulder pain or an elbow injury and shift the search to other sources (for example, muscle strain, nerve irritation, or referred pain).

• Abnormal/positive: The images may show a specific injury (such as a labral tear, ligament sprain/tear, or cartilage defect), signs of chronic overuse, or joint disease. Pinpointing the exact structure involved helps guide treatment—such as physical therapy, activity modification, injections, or orthopedic procedures.

• Limited/indeterminate: Occasionally, motion during the scan or anatomy that is difficult to image may limit detail. Your care team may correlate the findings with your symptoms, exam, and other tests.

When & why it's usually done

Your clinician may order an MRI upper extremity arthrogram when a standard MRI, X-ray, or physical exam does not fully explain symptoms, or when they suspect subtle internal joint injury. It is especially helpful for people with sports injuries or repetitive overhead/throwing activities.

Common reasons include:

• Ongoing shoulder pain (or catching, clicking, popping) especially after a fall, dislocation, or overhead activity, when a labral tear or ligament injury is suspected.

• Suspected joint instability, such as a shoulder that feels like it “slips,” recurrent dislocations/subluxations, or a sense of looseness during movement.

• Elbow injury with pain on the inner or outer side of the elbow, loss of function, or instability—often related to ligament damage in throwing athletes.

• Wrist joint pain after trauma or repeated strain, especially when a tear of cartilage structures or ligaments is suspected and needs detailed imaging.

• Reduced range of motion, stiffness, or pain that has not improved with conservative care (rest, anti-inflammatory medication, or physical therapy).

• Pre-surgical planning or postoperative evaluation when your orthopedic specialist needs precise information about cartilage, ligament, or labral integrity.

Because contrast is placed inside the joint, this study can highlight small tears that may allow contrast to track into areas it normally wouldn’t—helping clarify the cause of symptoms like shoulder pain, weakness, or mechanical locking.

Common diseases related to it

• Shoulder labral tears (including SLAP tears and Bankart lesions)
• Shoulder instability and recurrent dislocation/subluxation
• Glenohumeral cartilage injury and osteochondral defects
• Ligament sprains/tears of the shoulder, elbow, or wrist
• Ulnar collateral ligament (UCL) injury of the elbow (common in throwing sports)
• Triangular fibrocartilage complex (TFCC) tears of the wrist
• Wrist ligament injuries (e.g., scapholunate or lunotriquetral ligament tears)
• Rotator cuff pathology (partial-thickness tears may be better defined in some cases)
• Adhesive capsulitis (frozen shoulder) and capsular abnormalities
• Inflammatory or degenerative joint conditions affecting the upper extremity (e.g., arthritis-related cartilage wear)

Health goals where it may help

• Identifying the cause of persistent shoulder pain, elbow pain, or wrist pain to target the right treatment
• Confirming and characterizing soft tissue injuries (labrum, cartilage, ligaments, tendons) after trauma or overuse
• Improving recovery planning for sports injuries and safe return-to-play decisions
• Guiding orthopedic diagnosis and determining whether surgery or non-surgical care is most appropriate
• Assessing joint stability and preventing repeat injuries by identifying underlying structural problems
• Monitoring healing or evaluating ongoing symptoms after prior injury or orthopedic repair
