Fig. 2From: MR arthrography: correlation between anatomic intraarticular variants of the long head of the biceps tendon (long head biceps tendon) and superior labral anterior to posterior (SLAP) lesionsa MR arthrography, sagittal SE T1-weighted. In MESO-PA anatomical variant, long head biceps tendon is partially fused to the inferior surface of the supraspinatus tendon (arrow). Contrast agent outlines acute angle between the anterior portion of the long head biceps tendon and the inferior surface of the supraspinatus (curved arrow). b Same patients as in a.
