Acetabular labral tears are a mechanical cause of hip pain. Hip MR imaging should be performed on 1.5-T or 3-T magnets using small field-of-view and high-resolution imaging. The following should be used in the assessment for labral tear abnormalities on MR arthrography: labral morphology and contrast extension into the labral substance or between the labral base and acetabulum. Description of the labral tear and extent of tear is useful for hip arthroscopists. Understanding the pitfalls around the acetabular labral complex helps avoids misinterpretation of labral tears.
