From: Isolated bursal-side infraspinatus tear diagnosed by computed tomography bursography: a case series
The infraspinatus tear is visualized by Computed tomography bursography. However, axial and sagittal T2-weighted MR images without fat suppression show a normal rotator cuff. a The axial image on Computed tomography bursography shows longitudinal pooling of contrast medium in the infraspinatus (arrowhead). b The sagittal image reveals that it communicates with the subacromial bursa near the insertion of the infraspinatus tendon (arrowhead) and (c, d) within the infraspinatus tendon and muscle body (arrowhead).
