Role of CT arthrogram in the evaluation of acetabular labrum and acetabular cartilage:
Nishii T et al. of Japan evaluated 41 hips CT arthrogram with radial reformation for detection of acetabular labral and articular cartilage disorders. The sensitivity, specificity and accuracy was very high for both (97%, 87% and 92% for labral tears and 88%, 82% and 85% for acetabular cartilage disorder).
Labral and acetabular cartilage disorders were most common in anterior zone.
