MRI of tendinopathy of the common extensor tendon and common flexor tendon and its application for injury classification

Motivation: We analyzed magnetic resonance imaging (MRI) features of the elbow tendons to provide information for early diagnosis and treatment. Goal(s): To analyze the injury classification of the common extensor tendon (CET) and common flexor tendon (CFT) tendinopathy by MRI. Approach: 62 patients with elbow tendinopathy as the case group and 20 healthy subject as the control group. All subjects underwent elbow MR examination. The MRI of tendinopathy were read by 2 senior radiologists independently, and the consistency was tested by the κ test. The MRI manifestations for injury classification were discussed. Results: MRI can be used to diagnose tendinopathies and classify injuries. Impact: Tendinopathy of CFT and CET of elbow joint has its characteristic MRI manifestations, indicating that MRI can be used for the diagnosis injury classification of tendinopathy. In addition, MRI can also be used for the injury classification.
