【摘要】：目的对磁共振扩散加权成像(DWI)鉴别诊断胰腺癌和肿块型慢性胰腺炎的文献进行汇总复习,评价DWI对胰腺癌与肿块型慢性胰腺炎的鉴别诊断价值。方法检索主要中、英文数据库,提取相关参数,采用Stata12.0及Meta-Disc 1.4软件进行Meta分析。结果 DWI对该两种疾病鉴别诊断汇总敏感度为0.864(95%CI:0.799,0.910),汇总特异度为0.816(95%CI:0.716,0.886),汇总阳性似然比4.694(95%CI:3.013,7.312),汇总阴性似然比0.167(95%CI:0.114,0.244),汇总诊断比值比为28.137(95%CI:15.562,50.872),汇总受试者工作特征曲线(SROC)下面积(AUC)为0.91(95%CI:0.88,0.93)。结论 DWI用于鉴别诊断胰腺癌与肿块型慢性胰腺炎具有较高的诊断准确性。
