Fig. 1From: 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) lesionsThe images in a–d are all T1-weighted MR arthrographies, acquired in coronal-oblique section after intraarticular injection of approximately 20 ml of paramagnetic contrast agent. In particular, image a shows a type I SLAP lesion (arrowhead); image b shows a type II SLAP lesion (arrowheads) that does not reach the bicipital anchor (arrow); image c displays a type III SLAP lesion where the lesion (arrowhead) extends in a centrifugal direction alongside the bicipital anchor (curved arrow) delimiting a triangular fragment of fibrocartilage (star); image d displays a type IV SLAP lesion where the lesion (thick arrow) reaches and interrupts part of the bicipital anchor (thin arrow). c and d are reprinted with the permission of E.
