CT arthrography provides excellent imaging of osseous detail allowing for characterization of glenoid morphology, version, and bone loss. Unlike nonarthrogram CT, CT arthrography allows for adequate characterization of a rotator cuff tear [16,17], which may alter the chosen arthroplasty type. Arthrogram contrast also outlines the articular cartilage surface, demonstrating areas of cartilage loss, which cannot be directly visualized with conventional CT. CT Shoulder With IV Contrast There is insufficient evidence to support the use of CT shoulder with IV contrast in the evaluation of chronic shoulder pain when initial radiographs demonstrate osteoarthritis. CT Shoulder Without and With IV Contrast There is insufficient evidence to support the use of CT shoulder without and with IV contrast in the evaluation of chronic shoulder pain when initial radiographs demonstrate osteoarthritis. CT Shoulder Without IV Contrast CT can be helpful in evaluating osseous morphology in cases in which arthroplasty surgery is under consideration for treatment of severe glenohumeral arthritis. CT images are commonly obtained to classify the morphology of the glenoid according to the Walch classification system [140]. CT measurements of glenoid version, glenoid bone loss, and humeral head subluxation demonstrate high interrater reliability [141]. CT can potentially demonstrate rotator cuff muscle fatty infiltration, which is often associated with rotator cuff tears; however, overall sensitivity for full thickness rotator cuff tears is only 20% for noncontrast CT [19]. FDG-PET/CT Skull Base to Mid-Thigh There is insufficient evidence to support the use of FDG-PET/CT skull base to mid-thigh in the evaluation of chronic shoulder pain when initial radiographs demonstrate osteoarthritis.
