[Modern imaging in radioanatomic study of the shoulder]

The authors describe the most appropriate imaging technique or techniques for assessment of each anatomical structure in the shoulder: the head of the humerus, socket, acromion, joint space, labrum, musculotendinous structures of the supraspinatus, subscapularis and long biceps muscles. The techniques used are the most useful view of standard X-rays, as well as arthropathy, CT scan, arthroscan, ultrasonography and MRI. This is a preliminary study to assessment of shoulder lesions. In the shoulder, radiologists are frequently required to identify the anatomical disorder as exactly as possible without falling into the traps associated with all forms of imaging even the most sophisticated.
