title: [MR image-guided anterior direct arthrography of the shoulder].
abstract: OBJECTIVE
  To investigate the method of MR guided anterior direct arthrogaphy of shoulder and its clinical applications.
  
  
  METHODS
  From 2008.4 to 2008.10, 40 patients with rotator-cuff tear (29 males and 11 females, ranging in age from 22 to 70 years, with an average of 35 years) underwent MR guided anterior direct arthrogaphy of shoulder, so as to diagnosis shoulder wound. The results were compared to that of arthroscopy.
  
  
  RESULTS
  Shoulder arthrography showed lesons in 36 patients, and failure in 2 patients, including contrast media extravasation in 1 patient, and gas entry to joint cavity in 1 patient. Two patients showed no rotator cuff injuries. Twenty-eight patients were confirmed by arthroscopy as rotator-cuff injured in different degree. Twenty-six patients were confirmed injuries by both arthroscopy and MR guided anterior direct arthrogaphy.
  
  
  CONCLUSIONS
  MR guided anterior direct arthrogaphy of shoulder as a minimally invasive method in displaying the rotator-cuff tear has higher accuracy and wide clinical application prospect.
