| Abstract | ||
| Background: Femoroacetabular impingement (FAI) is defined as an abnormal femoral acetabular contact that occurs within the normal range of motion caused by alterations of the acetabulum and/or the femoral head or neck. Objective: The purpose of this study was to compare the diagnostic performance of MR arthrography (MRA) with arthroscopic correlation for detecting labral tears and articular cartilage abnormalities. Materials and Methods: MRA was performed in 29 patients (16 males, 13 females with symptomatic FAI. The MRI images assessed for presence of labral tears, chondral lesions and osseous abnormalities. Arthroscopic correlation was obtained in all cases. Results: The sensitivity, specificity, PPV, and NPV of MRA for detecting labral tears were 87.5 %, 71.4%, 91.3% and 62.5%, respectively. The sensitivity, specificity, PPV, and NPV of MRA for detecting chondral damage were 76.5%, 91.7%, 86.7% and 78.6% respectively. Conclusion: MRA appears to be an accurate imaging modality in the evaluation of labral tears. MRA is less accurate in the diagnosis of cartilage abnormalities in the hip. | ||
