Reporting rotator cuff tears on magnetic resonance arthrography using the Snyder’s arthroscopic classification

Figure 2 Magnetic resonance arthrography of a C1 tear of the supraspinatus tendon. A: MRA coronal, double echo steady state. Viewfinder shows the hyperintense signal in supraspinatus tendon, expression of full tear (C1 lesion according to Snyder classification); B: MRA Sagittal TSE T1w. Yellow arrows show the full tear (C1 lesion according to Snyder classification). White arrows show the degenerative tendon matrix, later removed by the surgeon; C: Arthroscopic view. White dotted line show a full, V-shape, tear of supraspinatus tendon completed to C2 according to Snyder classification by the surgeon. MRA: Magnetic resonance arthrography.
