title: [Cine-MRI of the shoulder. Normal aspects].
abstract: OBJECTIVE
  To define the normal patterns of gleno-humeral joint, with kinematic MR imaging in asymptomatic volunteers.
  
  
  METHODS
  Twenty asymptomatic volunteers (39 shoulders) were studied with a 1.5 Tesla imager. Successive acquisitions Flash (99, 18, 15 degrees) were obtained in the axial plane, from full internal to full external rotation, at the superior, mid and inferior glenoid level.
  
  
  RESULTS
  Free edge of the anterior labrum was noted slightly mobile, its base was always immobile. The anterior labrum exhibited modification of shape and increased signal intensity in internal rotation (54%). The posterior labrum remained motionless in 97% and neither shape or signal intensity changes were noted in internal rotation. Inferior labro-capsular ligamentous complex was visualised in all cases. The anterior capsular joint was taut in external rotation and exhibited a slack (51%) or folded (13.5%) pattern during internal rotation.
  
  
  CONCLUSIONS
  Kinematic MR imaging allows a dynamic assessment of the different anatomic components which may be implicated in shoulder instability. It provides information about the labro-capsular ligamentous complex.
