The value of MR shoulder arthrography in diagnosis of rotator cuff injury

Objective To investigate the value of MR shoulder arthrography in diagnosis of rotator cuff injury. Methods160 patients with rotator cuff injury admitted into our hospital from January 2013 to December 2014 were selected,and they were confirmed by conventional MRI preoperatively diagnosed and confirmed during surgery for rotator cuff injury,among them,85 patients were underwent MR angiography examination,among 85 patients,31 patients were underwent arthroscopic diagnosis and treatment. Results In 31 patients given arthroscopic diagnosis and treatment,there were 8cases of full thickness rotator cuff tear,diagnostic accuracy rate of MRI was 62.50%,diagnostic accuracy rate of MR angiography was 100.00%;there were 19 cases of partial tear of the rotator cuff,diagnostic accuracy rate of MRI was57.89%,diagnostic accuracy rate of MR angiography was 100.00%;there were 5 cases of rotator cuff degeneration,diagnostic accuracy rate of MRI was 40.00%,diagnostic accuracy rate of MR angiography was 100.00%;there were 9 cases rotator cuff tear complicated with labrum injury,diagnostic accuracy rate of MRI was 44.44%,diagnostic accuracy rate of MR angiography was 100.00%; diagnostic accuracy rate of MR angiography was higher than that of MRI,the difference was statistically significant(P0.05). Conclusion The accuracy rate of MR angiography in the diagnosis of rotator cuff injury is higher than MRI.
