Abstract

This unit presents protocols for MR imaging of masess of the elbow using T1‐ and T2‐weighted sequences. An alternative method using post‐contrast images is also provided, which may help to differentiate cystic or necrotic lesions from solid masses by defining a nodular or peripheral enhancing component in a cystic lesion versus more diffuse enhancement in a solid mass.

Keywords: elbow imaging; fat‐suppressed sequences; contrast‐enhanced sequences
