| 目的 与关节镜对比，观察3.0T MR单侧髋关节扫描诊断圆韧带损伤的价值。方法 回顾性分析41例慢性髋关节疼痛患者术前髋关节MRI，包括双侧髋关节及单侧髋关节扫描MRI，以关节镜结果为金标准，比较两种扫描方式诊断圆韧带损伤的差异。结果 41例中，34例圆韧带损伤，其中4例单髋MRI显示正常；7例正常，其中1例单髋MRI显示为圆韧带部分撕裂。双髋及单髋MRI诊断圆韧带损伤的敏感度、特异度、阳性预测值、阴性预测值及准确率分别为58.82%（20/34）、88.24%（30/34）、57.14%（4/7）、85.71%（6/7）及86.96%（20/23）和96.77%（30/31）、22.22%（4/18）、60.00%（6/10）、58.54%（24/41）及87.80%（36/41）。单髋MR扫描的AUC大于双髋扫描（P=0.02）。结论 3.0T MR单侧髋关节扫描诊断圆韧带损伤能力较好。 |

| 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. |
