Magnetic Resonance Imaging of the Elbow: A Systematic Approach

Presentation Format: Educational poster presentation.

Purpose or Learning Objective: (1) To learn the magnetic resonance imaging (MRI) anatomy of the elbow; (2) to provide a systematic approach for evaluating elbow pathologies; (3) to highlight static and dynamic stabilizers that are important in evaluating elbow instability; and (4) to offer a pictorial review of various elbow pathologies.

Methods or Background: MRI is commonly performed in the traumatic setting to evaluate the elbow ligaments and integrity of the tendons. Thus it is imperative for the radiologist to understand the pattern of involvement of static and dynamic stabilizers in various types of elbow instability. MRI is also useful in evaluating elbow pain, soft tissue swelling, and nerve compression syndrome. Because the elbow is a complex joint, a systematic approach is important to identify various abnormalities.

Results or Findings: These topics are covered in the poster presentation: (1) Normal anatomy of the elbow explained using the categories of bones, ligaments, tendons, bursae, and nerves; (2) various elbow pathologies and associated MRI findings; and (3) a radiologic checklist for reporting the results of MRI of the elbow.

Conclusion: Understanding the normal anatomy of the elbow joint helps the radiologist identify the abnormality, thereby ensuring accurate diagnosis.
