低张CT胆道成像MinIP联合CPR对胆道梗阻的诊断价值
Diagnostic value of MinIP combined with CPR in low tension CT cholangiography for biliary obstruction
摘要
Abstract
Objective:To explore the diagnostic value of MinIP combined with CPR in low tension CT cholangiography for biliary obstruction.Methods:A total of 210 patients who were clinically suspected biliary obstructive disease and underwent CT cholangiography were prospectively selected as the research subjects.All patients were randomly divided into the routine group(Group A)and the low tension groups(Group B1 and Group B2)using a random number table,with 70 patients in each group.Group A underwent CT under normal tension,and the images were post-processed with MPR.Group B1 and B2 were scanned after filling the duodenum by drinking water several times in different stages under low tension,and the images of Group B1 were post-processed with MPR,while the images of Group B2 were post-processed with MinIP and CPR.All images were analyzed,the location and qualitative diagnosis of biliary obstruction had been made,the diagnostic values were compared among the three groups.Results:Compared to the accuracy of location diagnosis for biliary obstruction among the three groups,Group B2 had the highest accuracy of 97.14%(68/70),followed by Group B1 of 84.29%(59/70),and Group A had the lowest accuracy of 65.71%(46/70).The qualitative diagnostic accuracies in Group B1 and B2 were 91.43%(64/70)and 95.71%(67/70),respectively,which were higher than the accuracy of 77.14%(54/70)in Group A(both P<0.05).The positive predictive value of Group B1,the negative predictive value and sensitivity of Group B2 were 96.55%(28/29),97.73%(43/44)and 96.00%(24/25),respectively,which were all higher than those in Group A(all P<0.05).Compared to surgical pathology or ERCP findings,Group B1 and B2 had the excellent diagnostic consistency(K=0.826,0.907),while Group A had the moderate consistency(K=0.529).Conclusions:Compared to conventional methods,MinIP combined with CPR in low tension CT cholangiography can significantly improve the location and qualitative diagnosis for biliary obstruction,and has a higher clinical value.关键词
