摘要
目的:评估MRI单一方位扫描和综合3个方位扫描成像对于前下盂唇Bankart损伤的诊断价值。方法:以关节镜表现作为诊断金标准,分析31例Bankart损伤者的MRI表现,分别计算单一方位和综合3个方位扫描对肩关节盂唇Bankart损伤诊断的敏感度、特异度、阳性预测值、阴性预测值、准确度。结果:横轴位扫描对Bankart损伤的诊断敏感度为54.84%、特异度为80.77%;斜冠位敏感度为45.16%、特异度为84.61%;斜矢位敏感度为41.94%、特异度为88.46%;综合3个方位扫描的诊断敏感度为80.65%、特异度为88.46%。综合3个方位扫描诊断Bankart损伤的敏感度高于单一方位扫描,比较差异均有统计学意义(均为P<0.05)。结论:对疑有Bankart损伤患者行肩关节MRI扫描,扫描方位应包括横轴位、斜冠位和斜矢位。
Objective： To evaluate and compare the diagnostic value of single-directional scanning and inte- grated three-position MRI of in Bankart lesion of anterior inferior labrum. Methods： Using arthroscopic per/brm- ance as diagnostic golden standard, we retrospectively analysed the MRIs of 31 cases with Bankart lesion. We cal- culated the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the diagno- sis of Bankart lesion using various single-directional scan and integrated three-position MRI. Results： The sensitivi- ty and specificity o f Single axial scan, single oblique coronal scan, single oblique sagittal scan and comprehensive three-azimuth scan for the Bankart lesion diagnosis was 54.84% and 80.77% , 45.16% and 84.61% , 41.94% and 88.46% , 80.64% and 88.46% , respectively. The diagnostic sensitivity of integrated three-azimuth scan was higher than that of single-directional scan, with statistical significance. Conclusion： Conventional scanning pro- gram of patients with suspicion of Bankart lesion should take a comprehensive MRI including the horizontal axis bit, oblique coronal and oblique sagittal.
