2017 Orthopaedic Sports Medicine Review Course Online-Imaging: Shoulder

Video Transcription

Video Summary

The video discusses various imaging planes and techniques used in MRI shoulder protocols. It mentions that there are three major imaging planes: axial, oblique coronal, and oblique sagittal. The ABER sequence, which stands for abduction external rotation, is used in orthographic studies and involves placing the patient's hand behind their head and redoing the coil over the shoulder to obtain images. To prescribe the oblique coronal sequence, technicians are usually asked to make it parallel to the supraspinatus muscle on an axial image, while the oblique sagittal sequence is perpendicular to the oblique coronal sequence. The video also emphasizes the importance of taking into account glenoid bone loss in evaluating the antero-inferior glenoid rim. It touches on the Coracoacromial arch and its significance in certain pathologies. The video concludes with a discussion on rotator cuff tears and labral tears, as well as the imaging findings associated with glenohumeral instability. The use of CT imaging for assessing glenoid rim defects is also mentioned. No credits were mentioned in the video.
