Fig. 21A. MR arthrograms of right shoulder in man with shoulder pain
and superior labral anteroposterior (SLAP) lesion. HH = humeral head, G =
glenoid. Coronal T1-weighted fat-suppressed image (TR/TE, 600/15) shows
abnormal morphology at insertion site of biceps tendon (arrow). This
finding was initially interpreted as double Oreo cookie sign. Sequential
images (not shown) revealed partial volume with superior glenohumeral
ligament.
