Abstract:
Objective To explore the value of the morphological quantitative indexes and the number of emboli in predicting heart function in patients with acute pulmonary embolism (APE)based on computer-aided diagnosis (CAD)technique.Methods One-hundred and forty-eight APE patients confirmed by CT pulmonary angiography (CTPA)in our hospital.Total number of emboli (N)and three morphological quantitative indexes,including total volume of emboli (V),total length (L)and total maximum cross-section embolism proportion (P)were obtained by CAD.The maximal short axis and area of left and right ventricular (LVd,RVd,LVS,RVS)were measured by hand on axial image to calculate the ratio of maximal short axis of right and left ventricular (RVd/LVd)and ratio of maximal area of right and left ventricular (RVS/LVS).The correlation of the above indexes was analyzed by the Pearson correlation of SPSS 22.0.Results The ranking of the correlation between CAD indexes and the heart function was in the order of V,L,P and N.The correlation between CAD indexes and the right heart function was greater than that of the left heart.The V had the strongest correlation with RVd (r=0.544,P=0.000),RVS (r=0.515,P=0.000),RVd/LVd (r=0.595,P=0.000)and RVS/LVS (r=0.579,P=0.000),respectively.While other the CAD indexes had lower correlation with the heart function (|r|:0.167-0.476,P<0.05),and there was no correlation between the N and the left heart function.Conclusion In embolic morphology and quantitative indexes,the V is the best quantitative index to reflect the change of right heart function in APE,which can reflect dys-function of right heart and severity of pulmonary embolism dis-ease in the APE embolism patient.
