Direct MR Arthrography of the Hip: Diagnosis and Pitfalls of Acetabular Labral Lesions

MR Arthrography: Superior Labral Anterior-Posterior (SLAP) Lesions

Reliability and validity of diagnosing acetabular labral lesions with magnetic resonance arthrography.

BACKGROUND Arthroscopic surgery of the hip is being increasingly used to diagnose and treat various abnormalities, including acetabular labral tears. Magnetic resonance arthrography has been suggested as the imaging test of choice for the evaluation of the acetabular labrum. There is substantial variability in the previously reported accuracy of magnetic resonance arthrography for diagnosing la...

Diagnosis of lesions of the acetabular labrum, of the labral-chondral transition zone, and of the cartilage in femoroacetabular impingement: Correlation between direct magnetic resonance arthrography and hip arthroscopy.

OBJECTIVE To determine the sensitivity and accuracy of direct MR arthrography in the diagnosis of intra-articular lesions associated with femoroacetabular impingement. MATERIAL AND METHODS We used direct MR arthrography to study 51 patients with femoroacetabular impingement who underwent arthroscopic hip surgery. Surgery demonstrated 37 labral tears, 44 lesions in the labral-chondral transiti...

MR and CT arthrography of the hip.

CT arthrography (CTa) and MR arthrography (MRa) are useful tools for the investigation of intra-articular hip disease. They are minimally invasive techniques with a very low rate of complications and can be performed safely. CTa or MRa can be performed after an intra-articular injection of diluted contrast, but both techniques can also be performed after a single injection. As radiologists we s...

Acetabular labral tear and postpartum hip pain.

OBJECTIVE To educate the obstetrics community regarding postpartum labral tears, an avoidable and treatable potential complication of pregnancy in the postpartum period. METHODS From 2009 to 2011, 10 women presented to the second author's office with persistent hip pain that had begun during pregnancy or during delivery. These 10 postpartum women presented with signs and symptoms of labral te...
