目的：探讨MRI和MR关节造影在肩关节前方盂唇损伤中的诊断价值,评估MR关节造影在鉴别肩关节前方盂唇不同类型损伤中的作用。
方法：自2007年1月至2010年12月,对经肩关节MRI、MR关节造影诊断后进行关节镜手术治疗的153例肩部损伤患者的临床资料进行了回顾性分析。由1位骨骼肌肉系统影像学医生和1位运动医学医生共同阅片,得出一致的MRI和MR关节造影诊断,并与关节镜下结果进行比较。计算MRI和MR关节造影诊断肩关节前方盂唇损伤的敏感性、特异性和准确性。在MR关节造影下存在前方盂唇损伤的患者中,对其不同类型损伤进行分型,与关节镜下分型进行对比研究。
结果：153例中,肩关节前方盂唇损伤78例,肩袖损伤67例,上盂唇从前到后(superior labrum anterior to posterior,SLAP)损伤8例,MRI和MR关节造影诊断肩关节前方盂唇损伤的灵敏度分别为80.8%和92.3%,特异度分别为89.3%和97.3%,准确度分别为85.0%和94.8%.78例关节镜下存在肩关节前方盂唇损伤的患者中,Bankart损伤39例,前方盂唇骨膜袖套样撕脱(ALPSA)损伤32例,Perthes损伤7例,MR关节造影正确诊断Bankart、ALPSA和Perthes损伤的灵敏度分别为84.6%、84.4%和57.1%.
结论：MR关节造影较MRI诊断肩关节前方盂唇损伤的灵敏度、特异度和准确度更高,MR关节造影能在术前进一步明确盂唇损伤的类型,为确定术前计划提供依据。 |

Abstract:
Objective:To investigate the diagnostic value of MRI and MR arthrography in the detection of injuries of anterior labrum in shoulder and to evaluate the accuracy of MR arthrography in the classification of anterior labrum lesion.
Methods:Seventy-eight patients with arthroscopically proved anterior labrum lesions(study group) and 75 patients with arthroscopically proved intact anterior labrum(control group) from January 2007 to December 2010 were included to the study. All patients underwent MRI and MR arthrography at our institution prior to shoulder arthroscopy. All MRI and MR arthrography were analyzed by one musculoskeletal radiologists and one sports medicine surgeon who had no knowledge of the clinical histories and arthroscopic results. The same classification system of labrum lesions based on arthroscopy was used in image analysis. Imaging findings and arthroscopic findings were compared in all patients. With arthroscopy used as the standard of reference,the sensitivities,specificities and accuracies of MRI and MR arthrography in the detection of anterior labrum lesions were compared,and the sensitivities,specificities and accuracies of MR arthrography in the correct classification of anterior labrum lesions were calculated.
Results:In arthroscopy,78 anterior labrum lesions,67 rotator cuff lesions and 8 SLAP lesions were diagnosed,for the detection of anterior labrum lesions,the sensitivity of MRI and MR arthrography was 80.8% and 92.3%,the specificity was 89.3% and 97.3%,the accuracy was 85.0% and 94.8% respectively. Seventy-eight patients with arthroscopically proved anterior labrum lesions included 39 Bankart lesions,32 ALPSA lesions and 7 Perthes lesions,with MR arthrography,Bankart,ALPSA,and Perthes lesions were correctly classified in 84.6%,84.4%,and 57.1% of cases,respectively.
Conclusion:MR arthrography has a higher sensitivity,specificity and accuracy than MRI in the detection of anterior labrum injuries. MR arthrography was useful in the classification of different variants of anterior labrum injuries before operations. It may directly influence the surgeon's strategy and is useful in preoperative planning of arthroscopic reconstructions. |
