Evaluation Value of Multislice Spiral Computed Tomography Imaging Parameters in Risk Stratification of Acute Pulmonary Embolism
Objective To explore the value of multi-slice spiral computed tomography(CT)pulmonary angiography imaging parameters in assessing the risk stratification of acute pulmonary embolism.Methods A total of 185 patients with acute pulmonary embolism admitted to the First Affiliated Hospital of Henan University of Traditional Chinese Medicine Hospital from January 2018 to December 2022 were selected as the research objects.According to their risk stratification,they were divided into the medium-low risk group,medium-high risk group and the high risk group,with 77 cases,64 cases and 44 cases,respectively.General data of the three groups were collected.and the imaging findings and imaging parameters of multi-slice spiral CT pulmonary angiography were compared.The value of multi-slice spiral CT pulmonary angiography imaging parameters alone and in combination in the diagnosis of high-risk acute pulmonary embolism was analyzed using receiver operating characteristic(ROC)curves.Results The proportion of patients with pulmonary artery and pulmonary artery involvement in the high-risk group and the high-risk group was higher than that in the low-risk group.The proportion of pulmonary artery involved in the high-risk group was higher than that in the high-risk group and the low-risk group,and the medium-high-risk group was higher than that in the low-risk group(P＜0.05).The main pulmonary artery(PA)/thoracic aorta(AO),superior vena cava diameter(SVC),right ventricular short axis diameter(RVD)/left ventricular short axis diameter(LVD)in the high-risk group were higher than those in the medium-high-risk group and the medium-low risk group,and the medium-high risk group was higher than those in the medium-low risk group(P＜0.05).The area under curve(AUC)value of PA/AO,SVC,RVD/LVD combined diagnosis was higher than that of the three diagnoses alone(P＜0.05).The sensitivity of PA/AO and combined diagnosis was higher than that of SVC and RVD/LVD,and the sensitivity of combined diagnosis was higher than that of PA/AO(P＜0.05).The specificity of SVC,RVD/LVD and combined diagnosis was higher than that of PA/AO(P＜0.05).Conclusion There were differences in the imaging findings of multislice spiral CT pulmonary angiography and in the imaging of PA/AO,SVC,and RVD/LVD of multislice spiral CT pulmonary angiography in patients with acute pulmonary embolism at different risk levels.The combination of PA/AO,SVC,and RVD/LVD has better diagnostic value for high-risk acute pulmonary embolism patients.
