What is an MRI of the Elbow?
An MRI of the elbow produces detailed images of the soft tissues, cartilage, tendons, ligaments, nerves, and bones of the elbow joint. Plain X-rays show bone but miss most soft tissue injuries — which are the most common cause of elbow pain in athletes and working adults. Elbow MRI is the investigation of choice when clinical examination and X-ray are insufficient to explain persistent elbow pain, weakness, or instability.
Why is an Elbow MRI Done?
- To diagnose lateral epicondylitis (tennis elbow) or medial epicondylitis (golfer's elbow) — tendon degeneration or tears at the elbow
- To evaluate ligament injuries — particularly the ulnar collateral ligament (UCL) in overhead athletes
- To assess osteochondral lesions — cartilage and underlying bone damage from repetitive stress
- To detect loose bodies — fragments of cartilage or bone floating inside the joint causing locking or catching
- To evaluate ulnar nerve entrapment at the elbow (cubital tunnel syndrome) causing tingling in the ring and little fingers
- To assess post-traumatic changes after elbow fracture or dislocation
How to Prepare for an Elbow MRI
- No fasting is required unless contrast is planned — fast for 4 hours if contrast is to be used
- Remove all metal objects from the arm — watches, rings, and bangles
- Inform staff about any metallic implants, plates, or screws around the elbow from previous surgery
- The elbow is typically positioned extended alongside the body or in the "superman" position above the head — the radiographer will advise the best position for the area of interest
- Bring previous X-rays and any relevant clinical reports
