What is an MRI of the Shoulder?
An MRI of the shoulder produces detailed images of the rotator cuff tendons, labrum, cartilage, bursa, ligaments, and bones of the shoulder joint. The shoulder is one of the most commonly injured joints — particularly the rotator cuff, which is a group of four tendons that stabilise and move the shoulder. X-rays show bone but cannot assess these soft tissue structures. Shoulder MRI is the definitive investigation for most soft tissue shoulder injuries and is essential for surgical planning.
Why is a Shoulder MRI Done?
- To diagnose rotator cuff tears — partial or full thickness tears of the supraspinatus, infraspinatus, subscapularis, or teres minor tendons
- To evaluate shoulder impingement syndrome — compression of the rotator cuff under the acromion bone
- To assess labral tears — the fibrocartilaginous rim of the glenoid socket, commonly torn in shoulder dislocations (Bankart lesion)
- To evaluate biceps tendon pathology — tendinopathy or tears at the shoulder attachment
- To assess glenohumeral joint cartilage and detect early arthritis
- To investigate subacromial bursitis causing shoulder pain and restricted movement
How to Prepare for a Shoulder MRI
- No fasting required for non-contrast MRI — fast 4 hours if contrast or intra-articular injection (MR arthrogram) is planned
- Remove all metal objects — jewellery, underwire bras, and any metallic items from the upper body
- Inform staff about any shoulder implants, plates, or previous shoulder surgery with metallic hardware
- Wear loose comfortable clothing without metal fasteners on the upper body
- Bring previous X-rays, ultrasound reports, and the clinical referral for the radiologist
- Inform staff if you have claustrophobia — shoulder MRI requires the upper body to be inside the scanner bore
