View larger version (121K): [in a new window]   Fig. 1 —36-year-old man with normal hip MRI. Axial spin-echo T1-weighted image without intraarticular contrast material (TR/TE, 650/15; field of view, 19 cm) shows normal anterior labrum having typical low-signal-intensity triangular appearance (arrowhead). Low-signal-intensity structure just anterior to anterior labrum represents normal iliopsoas tendon (arrow) and should not be misinterpreted as tear of labrum.

Coronal spin-echo T1-weighted image with fat suppression after administration of intraarticular gadolinium (TR/TE, 500/15; field of view, 14 cm) shows normal, triangular low-signal-intensity superior labrum (arrow) with area of intermediate signal intensity undercutting labral attachment to acetabulum (arrowhead). This finding represents normal cartilage and should not be mistaken for labral abnormality.

Anterior labrum (arrow) appears diffusely low in signal intensity with no evidence of tear. Anterior labrum is poorly distinguished from adjacent iliopsoas tendon because of large field of view. At surgery, this patient had anterior labral tear.

Anterior labrum appears diffusely low in signal intensity (arrow) and was therefore interpreted as normal. However, at arthroscopy, patient was found to have anterior labral tear.

Contrast material is undercutting superior labrum (arrow), consistent with tear confirmed at arthroscopy.

Contrast material is undercutting anterosuperior labrum, consistent with tear (arrow) that was proven at surgery. Incidentally noted is herniation pit (arrowhead).
