ABSTRACT
Objective:
To investigate the value of 3.0T MR unilateral hip scan in the diagnosis of ligamentum teres tears.Methods:
Data of preoperative MRI and hip arthroscopy of 41 patients with chronic hip pain were retrospectively analyzed. Preoperative MRI included bilateral hip scans and unilateral hip scans. Taken arthroscopy as the gold standard, the differences of diagnosis of ligamentum teres tears were compared between bilateral and unilateral MR hip scans.Results:
Hip arthroscopy confirmed ligamentum teres tears in 34 hips, while unilateral hip MRI showed normal in 4 hips, 7 hips were normal, while unilateral hip MRI showed partial tear of ligamentum teres in 1 hip. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of bilateral hip MR scanning was 58.82% (20/34), 88.24% (30/34), 57.14% (4/7), 85.71% (6/7) and 86.96% (20/23), while of unilateral hip MR scan were 96.77% (30/31), 22.22% (4/18), 60.00% (6/10), 58.54% (24/41) and 87.80% (36/41), respectively for diagnosing ligamentum teres tears. Unilateral hip scanning had larger AUC than bilateral hip scan (P=0.02).Conclusion:
3.0T MR unilateral hip scan is has good value for diagnosis of ligamentum teres tears.
