Recently published data indicated for the detection of full-thickness tears of the biceps tendon, the noncontrasted MRI had low sensitivity and high specificity and for the instability diagnosis fir the long head of the biceps, MRI had high sensitivity.
Researchers prospectively collected surgical data on 183 patients who underwent arthroscopic rotator cuff surgery for impingement syndrome, rotator cuff tears and also of those without bicep disease from 2003 to 2014. Radiologists with fellowship musculoskeletal imaging training retrospectively reviewed MRIs and compared with surgical data.
Results showed the sensitivity of MRI detecting partial-thickness bicep tears was 0.27 and the specificity was 0.86. Complete tears of bicep tendon has a sensitivity for MRI detection of 0.54 and a specificity of 0.98. Sensitivity and specificity for subluxation/dislocation was 1.00 and 0.83, respectively. The area under the receiving operating characteristic curves was 0.76 in full-tears. Investigators noted the area under ROC curve was 0.57 in partial tears and 0.92 for instability. ‒ by Monica Jaramillo
