【摘要】：目的對磁共振擴(kuò)散加權(quán)成像(DWI)鑒別診斷胰腺癌和腫塊型慢性胰腺炎的文獻(xiàn)進(jìn)行匯總復(fù)習(xí),評價(jià)DWI對胰腺癌與腫塊型慢性胰腺炎的鑒別診斷價(jià)值。方法檢索主要中、英文數(shù)據(jù)庫,提取相關(guān)參數(shù),采用Stata12.0及Meta-Disc 1.4軟件進(jìn)行Meta分析。結(jié)果 DWI對該兩種疾病鑒別診斷匯總敏感度為0.864(95%CI:0.799,0.910),匯總特異度為0.816(95%CI:0.716,0.886),匯總陽性似然比4.694(95%CI:3.013,7.312),匯總陰性似然比0.167(95%CI:0.114,0.244),匯總診斷比值比為28.137(95%CI:15.562,50.872),匯總受試者工作特征曲線(SROC)下面積(AUC)為0.91(95%CI:0.88,0.93)。結(jié)論 DWI用于鑒別診斷胰腺癌與腫塊型慢性胰腺炎具有較高的診斷準(zhǔn)確性。
