【摘要】：目的系统评价磁共振成像诊断髋臼唇撕裂的价值。方法计算机检索CBM、CNKI、VIP、WanFang Data、PubMed、EMbase、The Cochrane Library和Web of Science数据库,搜集磁共振成像诊断髋臼唇撕裂的诊断性试验,检索时限为1990年1月至2016年10月。由2位研究者按纳入与排除标准独立筛选文献、提取资料和利用QUADAS-2工具评价纳入研究的偏倚风险后,采用Stata 12.0软件进行Meta分析,计算合并敏感度、特异度、阳性似然比、阴性似然比、诊断比值比,绘制受试者工作特征曲线(SROC曲线)并计算曲线下面积(AUC)。结果最终纳入21篇文献的25个研究,包括1 099例患者和1 123个髋关节。Meta分析结果显示,磁共振平扫诊断髋臼唇撕裂的Sen合并=0.66[95%CI(0.38,0.86)]、Spe合并=0.72[95%CI(0.47,0.89)]、+LR合并=2.37[95%CI(1.18,4.76)]、 LR合并=0.48[95%CI(0.25,0.92)]、DOR合并=4.97[95%CI(1.60,15.47)]、AUC=0.75[95%CI(0.71,0.79)]。磁共振髋关节造影诊断髋臼唇撕裂的Sen合并=0.86[95%CI(0.80,0.90)]、Spe合并=0.71[95%CI(0.55,0.83)]、+LR合并=2.91[95%CI(1.77,4.80)]、 LR合并=0.20[95%CI(0.13,0.32)]、DOR合并=14.44[95%CI(5.80,35.95)]、AUC=0.87[95%CI(0.84,0.90)]。结论磁共振成像对诊断髋臼唇撕裂具有明确的诊断价值,使用磁共振髋关节造影的病例具备更高的诊断效能。
[Abstract]:Objective to evaluate the value of magnetic resonance imaging (MRI) in the diagnosis of acetabular lip tear. Methods the Cochrane Library and Web of Science databases were searched by computer for the diagnosis of acetabular lip tear. The search time was from January 1990 to October 2016. After the two researchers independently sifted the literature according to the inclusion and exclusion criteria, extracted the data and evaluated the bias risk of the inclusion study by using QUADAS-2 tools, the Meta analysis was carried out with Stata 12.0 software. The combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic ratio ratio and SROC curve were calculated and the area under the curve was calculated. The results were included in 25 studies of 21 articles. A meta-analysis of 1 099 patients and 1 123 hip joints showed that. Magnetic resonance imaging (MRI) was used to diagnose acetabular lip tear with Sen combined with 0.66 [95CI0.38 0.86] spar with 0.72 [95CII 0.470.89], LR with 2.37 [95CI1.184.76], LR with 0.48 [95CI0.250.992] DOR with 4.97 [95CI1.6015.47] [95CI0.710.79)]. Magnetic resonance imaging of hip arthrography in diagnosis of hip lip tear was 0.86 [0.800.900.90] spe combined with 0.71 [CI50.50.533], 2.91 [1.95804.74.80] [0.9595]. Imaging has a definite diagnostic value in the diagnosis of acetabular lip tear. Magnetic resonance hip arthrography is more effective in diagnosis.
