Context:The elbow is a complex joint and commonly injured in athletes. Evaluation of
the elbow by magnetic resonance imaging (MRI) is an important adjunct to the
physical examination. To facilitate accurate diagnosis, a concise structured
approach to evaluation of the elbow by MRI is presented.Evidence Acquisition:A PubMed search was performed using the terms elbow and
MR imaging. No limits were set on the range of years
searched. Articles were reviewed for relevance with an emphasis of the MRI
appearance of normal anatomy and common pathology of the elbow.Results:The spectrum of common elbow disorders varies from obvious acute fractures to
chronic overuse injuries whose imaging manifestations can be subtle. MRI
evaluation should include bones; lateral, medial, anterior, and posterior
muscle groups; the ulnar and radial collateral ligaments; as well as nerves,
synovium, and bursae. Special attention should be paid to the valgus
extension overload syndrome and the MRI appearance of associated injuries
when evaluating throwing athletes.Conclusion:MRI evaluation of the elbow should follow a structured approach to facilitate
thoroughness, accuracy, and speed. Such an approach should cover bone,
cartilage, muscle, tendons, ligaments, synovium, bursae, and nerves.
