The purpose of this study was to compare the diagnostic performance of fat‐saturation fast‐spin‐echo (FSE) T2‐weighted (T2W) sequences with conventional spin‐echo (CSE) T2W sequences in the detection of rotator cuff pathology using surgery as the reference standard. Oblique coronal dual‐echo CSE and FSE T2W images with fat saturation from 50 surgically confirmed MR shoulder examinations were acquired on a 1.5‐T MR scanner. Blinded MR readers retrospectively analyzed each imaging sequence separately and ultimately correlated both sequences together with findings at surgery. FSE was 100% sensitive and 94% specific in detection of full‐thickness tears ( n = 19) and 73% sensitive and 97% specific in the detection of partial‐thickness rotator cuff tears ( n = 13). There was no statistically significant difference in the performance of FSE with fat saturation compared with CSE. The two discrepancies between imaging sequences related to the extent of partial‐thickness tears. Our findings suggest that fat‐saturation FSE imaging can effectively replace CSE imaging in the evaluation of rotator cuff pathology.
