Abstract

PURPOSE
We performed the study prospectively to evaluate the advantage of fat suppression MR in the diagnosis of rotator cuff injury.
MATERIALS AND METHODS
Ten symptomatic patients were studied with both conventional T2WI and FST2WI using chemical shift technique. Each image was analyzed for the assessnent of injuries, conspicuity of the lesion, the presence of effusion in subacromial bursae and joint space, and presence of humeral head injury. Arthroscopy was done in 4 patients following MRI.
RESULTS
We could made presumptive diagnoses on FSMR as identical as on conventional MR in six cases(1 normal, 2 tendinitis, 2 partial thickness tear, 1 full thickness tear), two of them were confirmed by arthroscopic procedures. Two cases of partial thickness tear proved by arthroscopy were detected on FST2WI, whereas they were considered tendinitis on conventional T2Wl. There were another 2 cases who showed tendinitis on FSMR, but normal on conventional T2Wl. They, however, were not confirmed by either arthroscopy or surgical procedure.
CONCLUSION
We found the FSMR were superior to conventional T2Wl in the conspicuity of lesions and detection of joint effusion and abnormalities on the humeral head. We think FSMR of the shoulder could have significant diagnostic advantages over the conventional spin-echo MR imaging.
