英文摘要

Objective: To evaluate the value of hip MR for diagnosing acetabular labrum tears, and to further compare the diagnostic performances of conventional MR with MR arthrography in acetabular labrum tears.

Methods: 90 patients undergoing both hip MR examination and subsequent hip arthroscopy were retrospectively evaluated. Of these patients, 34 accepted both conventional MR and MR arthrography; while the other 56 only underwent conventional MR examination. All hip MR images were independently reviewed by two radiologists, and further compared with the results of hip arihroscopy.

Results: 59 of 90 patients were confirmed with acctabular labial fears by hip arthroscopy and 31 without fears. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of conventional MR for evaluating the acctabular labral fears were 61.0%, 774%, 83.7% and 51.1% (radiologist A), and 66.1%, 74.2%, 82.9% and 53.4% (radiologist B), respectively, with good consistency between the two observers (K=0.645). The sensitivity, specificity, PPV and NPV of MR arthrography for assessing the acetabular labial tears were 90.5%, 84.6%, 90.5% and 84.6% (radiologist A), and 95.2%, 84.6%, 90.9% and 91.7% (radiologist B), respectively, with excellent good consistency between the two observers (K=0.810). The sensitivity and NPV of MR arthrography for diagnosing the acetabular labial tears were significantly higher than those of conventional MR (both P< 0.05).

Conclusion: Hip MR arthrography is a reliable evaluation modality for diagnosing the acetabular labial tears, and its diagnostic performance is superior to that of conventional MR at 3.0T. (C) 2014 Elsevier Ireland Ltd. All rights reserved.
