摘要
目的研究1.5T盂唇放射状MRI扫描对髋关节盂唇撕裂的诊断价值。方法选择2017年12月到2019年12月30例髋关节盂唇撕裂患者作为研究对象,均进行1.5T盂唇常规MRI扫描、放射状MRI扫描,并以关节镜手术结果为“金标准”,分析常规MRI扫描、放射状MRI扫描在髋关节盂唇撕裂中的敏感度、特异度、准确度、阳性预测值、阴性预测值。结果30例患者中,常规MRI扫描评估显示共有45处盂唇正常,42处盂唇撕裂,3处盂唇退变;放射状MRI扫描评估显示共有49处盂唇正常,40处盂唇撕裂,1处盂唇退变;关节镜手术结果显示共有48处盂唇正常,41处盂唇撕裂,1处盂唇退变。以关节镜手术结果为准,30例患者中共有41处盂唇撕裂,常规MRI扫描的敏感度为70.45%、特异度为78.26%、准确度为74.44%、阳性预测值为75.61%、阴性预测值为73.47%;放射状MRI扫描的敏感度为95.00%、特异度为94.00%、准确度为94.44%、阳性预测值为92.68%、阴性预测值为95.92%。结论1.5T盂唇放射状MRI扫描可显著提高髋关节盂唇撕裂诊断的敏感度、特异度及准确度,从而提高临床诊疗效率。
Objective Tostudy thediagnostic value of 1.5T glenoid labrum radial MRI scan for hip glenoid labrum tear.Methods Thirty patients with hip and glenoid labrum tearfrom December 2017 to December 2019 were selected as the research subjects,and all performed 1.5T glenoid labrum MRI scan and radial MRI scan.The arthroscopic results were used as the gold standard to analyze the sensitivity,specificity,accuracy,positive predictive value,and negative predictive value ofconventional MRI scans and radial MRI scans in hip and glenoid labrum tear.Results Conventional MRI scan evaluation showedthata total of 45 glenoid labrums were normal,42 glenoid labrums were torn,and 3 glenoid labrums were degeneratedofthe 30 patients.Radial MRI scan evaluation showed that 49 glenoid labrums were normal,40 glenoid labrum labial tears,and 1 glenoidlabrumdegenerated.The results of arthroscopic surgery showedthat a total of 48 glenoidlabrums normal,41 glenoidlabrum tears,and 1 glenoidlabrum degenerated.Based on the results of arthroscopic surgery,there were 41 glenoid labrum tears in 30 patients.The sensitivity of conventional MRI scans was 70.45%,specificity was 78.26%,accuracy was 74.44%,positive predictive value was 75.61%,negative forecast value is 73.47%.The sensitivity of the radial MRI scan was 95.00%,the specificity was 94.00%,the accuracy was 94.44%,the positive predictive value was 92.68%,and the negative predictive value was 95.92%.Conclusion The 1.5T glenoid labrum radial MRI scan can significantly improve the sensitivity,specificity and accuracy of the diagnosis of hip glenoid labrum tears,thereby improving the clinical diagnosis and treatment efficiency.
