Abstract：Objective To study the predictive value of multi-slice CT pulmonary angiography(MSCTPA),D-dimer(D-D)and modified Geneva scale for pulmonary embolism(PE).Methods A total of 85 suspected PE patients admitted to our hospi-tal were selected as the study subjects,and their clinical data were retrospectively analyzed.All patients were examined by MSCTPA in our hospital,their D-D level was tested,and their modified Geneva scale score was assessed.Receiver operating characteristic(ROC)curve was used to compare the predictive value for PE,and the correlation of MSCTPA parameter,D-D and modified Geneva score was analyzed.Results diagnostic accuracy and Kappa consistency of MSCTPA for PE were higher than D-D and modified Geneva scores(P<0.05);PE index(CTI),D-D level and modified Geneva score of CTPA,in PE group were significantly higher than those in non-PE group(P<0.05);The AUC value and sensitivity of CTI,D-D level and modified Geneva score in combined diagnosis of PE were significantly higher than those in single diagnosis(P<0.05);CTI,D-D and modified Geneva scores were positively correlated(P<0.05).Conclusion MSCTPA,D-D and modified Geneva scale scores can all be applied to the diagnosis of suspected PE and have certain diagnostic value.However,a single diagnosis cannot com-pletely exclude the diagnosis of PE,and the combined diagnosis of PE has higher specificity.
