PURPOSE: Evaluation of the diagnostic value and confidence of contrast-enhanced MR imaging in @entity1 with @entity2633 in comparison to clinical diagnosis. MATERIAL AND METHODS: 42 consecutive @entity1 with clinically proven chronic @entity2633 and 10 @entity2720 of healthy controls have been examined on a 1.0 T MR-unit. Criteria for inclusion in the prospective study were: persistent @entity158 and a failed conservative therapy. The MR protocol included STIR sequence, a native, T2-weighted, fat-suppressed TSE sequence, and a Flash-2-D sequence. Also, fat-suppressed, T1-weighted SE sequences before and after administration of @entity7241 contrast media have been recorded. RESULTS: In 39/42 @entity1 the STIR sequence showed an increased SI of the common extensor tendon. Increased MR signal of the lateral collateral ligament combined with a thickening and a partial @entity397 or a full thickness tear have been observed in 15/42 cases. A @entity236 at the lateral epicondilus was noticed in 6 of the studied @entity1 and a joint effusion in 18/42 @entity1 . After administration of contrast media we noticed an average increase of SI by about 150%. However, enhanced MR imaging did not provide additional information. CONCLUSION: In MR imaging of @entity102 administration of @entity7241 does not provide additional information.
