中文摘要:
      目的 评估放射状重建3.0T MR髋臼唇三维稳态双回波(3D-DESS)图像诊断髋臼唇损伤的价值。方法 收集47例于1个月内接受3.0T MR 3D-DESS检查及关节镜检查的股骨髋臼撞击综合征(FAI)患者,对3D-DESS图像进行放射状重建显示髋臼唇。由2名影像科医师评估髋臼唇的前侧、外上侧及后侧区,观察医师间及医师内评估结果的一致性。以关节镜结果为金标准,评价放射状重建3D-DESS图像诊断髋臼唇撕裂的敏感度、特异度、准确率、阳性预测值和阴性预测值。结果 医师间(Kappa=0.89)及医师内(Kappa=0.93)MRI评估结果的一致性较好(P均<0.05)。2名医师诊断髋臼唇撕裂的敏感度、特异度、准确率、阳性预测值及阴性预测值分别为95.31%、93.50%、94.32%、92.42%及96.00%和98.43%、90.90%、94.32%、90.00%及98.59%,与关节镜结果的一致性均较好(Kappa均=0.89,P均<0.05)。结论 放射状重建3.0T MR髋臼唇3D-DESS图像诊断髋臼唇损伤的效能与关节镜检查相当。
英文摘要:
      Objective To observe the value of radial reconstruction of 3.0T MR acetabular labrum three-dimensional double echo steady-state (3D-DESS) images in diagnosis of acetabular labrum injury. Methods Forty-seven patients with femoracetabular impingement (FAI) who underwent 3.0T MR 3D-DESS scan and arthroscopy within 1 month were collected. Radial reconstruction of 3D-DESS images was performed to display the acetabular labrum, and the anterior, the external superior and the posterior labrum regions of the acetabular labrum were evaluated by 2 radiologists. The consistency of MRI results between 2 radiologists and within 1 radiologist were observed. Taken the results of arthroscopy as gold standards, the sensitivity, specificity, accuracy, positive and negative predictive value of radial reconstruction of 3D-DESS image for diagnosis of acetabular labrum tear were evaluated. Results MRI evaluations were consistent between 2 radiologists (Kappa=0.89, P<0.05) and within the same radiologist (Kappa=0.93, P<0.05). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of these 2 radiologists for diagnosing acetabular labrum injuries was 95.31%, 93.50%, 94.32%, 92.42%, 96.00% and 98.43%, 90.90%, 94.32%, 90.00%,98.59%, respectively. MRI results of 2 radiologists were consistent with those of arthroscopy (both Kappa=0.89, both P<0.05). Conclusion The efficacy of radial reconstruction of 3.0T MR acetabular labrum 3D-DESS images for diagnosing acetabular labrum injury was comparative to that of arthroscopy.
