“…13,17 There is also evidence to suggest that computed tomography (CT) arthrography may also be used to distinguish between normal variants and SLAP lesions but with significantly decreased capability of staging of SLAP lesions compared with MRA. 18 Limitations of this technique include poor assessment of associated partial-thickness rotator cuff tears, reduced sensitivity to the detection of paralabral cysts, inability to assess bone marrow, and the necessity for radiation exposure.…”

The fibrocartilaginous glenoid labrum contributes to shoulder stability and provides attachment for the long head of biceps tendon and the glenohumeral ligaments. The superior site of attachment of the long head of biceps (biceps anchor) represents a site of injury to the superior labrum where tearing may extend into the biceps tendon as well as anterior and/or posterior to the biceps anchor. Such tears are known as superior labrum anterior and posterior (SLAP) tears and are a cause of both shoulder instability and pain. SLAP tears are frequently seen in those undertaking repetitive frequent overarm activity such as throwing athletes and swimmers. This article reviews the mechanisms and types of SLAP tears and their imaging appearances. It also discusses associated injuries and pitfalls in diagnosing these injuries.

“…MDCT arthrography has been shown to be effective in accurately detecting SLAP lesions and distinguishing between normal variants affecting the anterosuperior labrum and labral-bicipital complex. [57][58][59] Chondral defects in various joints are well assessed using MDCT arthrography with accuracy in some cases superior to that of direct MR arthrography [60][61][62][63]. Sensitivity for abnormalities that do not involve the chondral surface, however, is limited when compared with conventional MR imaging.…”

The combined use of shoulder arthrography with MR and CT imaging offers distinct advantages over conventional nonarthrographic imaging techniques. The improved contrast and joint distension afforded by direct arthrography optimize evaluation of various intra-articular structures and help to define subtle abnormalities and distinguish normal variants from true shoulder pathology. In this article, we review the rationale and basic approaches to shoulder arthrography as well as the imaging appearance of the normal shoulder, anatomical variants, and pathology highlighted by this technique.

“…Waldt et al (10) reported that multidetector computed tomographic (CT) arthrography showed similar diagnostic performance. One reason specificity is lower than sensitivity is that many individuals have a sublabral recess, which might be mistaken for a labral tear (15). Hence, we hypothesized that diagnostic performance would increase if tension on the labral-bicipital complex from the glenoid insertion was applied during imaging.…”
