Abstract
The efficacy of ultrasonography (US) and MR imaging in evaluating rotator cuff tear were compared by using them to examine 2 2 shoulders. Of the 22, 18 had complete rotator cuff tears and 4 had incomplete tears. Both the sensitivity and the specif ity of US and MRI were satisfactory in detecting the 18 complete cuff tears. But US was superior to MR imaging in identifying the 4 incomplete cuff tears. Based on these results, it appears that US and MRI are useful for detecting complete cuff tear, but in evaluating the localization of the cuff tears, US is superior to MR imaging.
