- “MDCT arthrography is a valid alternative for shoulder imaging of patients with contraindications to MRI or after failed MRI. MDCT arthrography is accurate for assessment of a variety of shoulder abnormalities and, with further validation, may become the imaging test of choice for evaluation of the postoperative shoulder.”

AJR 2012 Mar;198(3):635-46. - “The bursae of the shoulder are small pouches lined by synovium that normally contain a film of synovial fluid and function to reduce friction by creating a lubricated surface between tightly apposed structures . Although anatomic variants exist, bursae do not normally communicate with the glenohumeral joint. The subacromial-subdeltoid bursa, the largest bursa of the shoulder, is situated between the rotator cuff tendons and the coracoacromial arch and deltoid muscle, facilitating movement between these structures.”

AJR 2012 Mar;198(3):635-46. - “The subcoracoid bursa is located between the subscapularis tendon in the posterior aspect and the coracoid process, the combined tendon of the short head of the biceps, and the coracobrachialis muscle in the superior aspect. Natural communications exist between the subcoracoid bursa and the subacromial-subdeltoid bursa.”

AJR 2012 Mar;198(3):635-46. - “The glenoid labrum is visualized in cross section as a triangular structure, although its configuration varies considerably. The base is attached to the peripheral edge of the glenoid fossa and hyaline cartilage, and the apex projects laterally. The normal glenoid labrum has a variety of shapes, sizes, and attachments. Usually the anterior labrum is thinner and more pointed, and the poste- rior labrum is commonly uniformly rounded in contour. The normal glenoid labrum is 3 mm high and 4 mm wide.”

AJR 2012 Mar;198(3):635-46. - “In patients who have undergone shoulder surgery, MDCT arthrography has been found to be substantially more accurate than nonar thrographic MRI . MDCT arthrography depicted postoperative rotator cuff and capsular-labral complex abnormalities with sensitivity of 92–94% and accuracy of 89–96%. The diagnostic performance of MRI of these patients was substantially lower with sensitivity of 19–25% and accuracy of 21–29% ”
