A) Coronal T2 MRI of a 55-year-old female patient interpreted as the presence of nearly complete rotator cuff rupture on the right shoulder (arrow: nearly complete rotator cuff rupture); B) Another coronal T2 section of the same patient, complete rupture of the supraspinatus was not detected in this patient’s operation, rotator cuff repair was not performed (arrow: stable supraspinatus tendon); C) Coronal T2 MRI of a 49-year-old female patient interpreted by radiologists as the presence of distal full-thickness supraspinatus rupture. No rotator cuff rupture was detected in this patient (arrow: tendon attachment site cannot be distinguished).
