摘　　要：目的:分析肺动脉栓塞的风险因素及CT影像特点,提高对肺动脉栓塞的CT诊断及预测水平。方法:回顾性分析109例临床怀疑为肺动脉栓塞患者的CT图像及相关临床资料,根据临床上评估肺动脉栓塞风险度的Wells标准,将患者分为低度、中度、高度风险性组。以CT诊断肺动脉栓塞为标准,对临床上相关风险因素Wells积分与CT诊断肺动脉栓塞进行统计学分析。结果:Wells积分不同风险度患者组间的肺动脉栓塞的阳性率差异有统计学意义(χ~2=53.084,P<0.05),以高度风险患者组的阳性率最高,达到93%。相关系数为0.658,提示Wells积分的风险度与肺动脉栓塞的阳性率呈显著正相关。结论:肺动脉栓塞Wells积分的风险因素分析能提高对肺动脉栓塞的认识,进一步提高CT对肺栓塞的诊断准确度以指导临床实践。Objective： To analyze the risk factors and CT characters of pulmonary embolism,improving the CT diagnostic accuracy and predictive level. Methods： 109 cases of CT pulmonary angiography and clinical data were retrospectively analyzed in patients with suspected pulmonary embolism. All patients were divided into low risk,moderate risk and high risk groups by Wells criteria for pulmonary embolism. Based on the standard of CT diagnosis of pulmonary embolism,clinical risk factors such as Wells score and CT data were also statistically analyzed. Results： The positive rates of pulmonary embolism in different risk groups were statistically significant（ χ^2= 53. 084,P〈0. 05）. The positive rate of high risk group was highest,up to 93%.Spearman＇s rank correlation coefficient was 0. 658,indicating a significant positive correlation between Wells score and positive rate of pulmonary embolism. Conclusion： Wells score risk factor analysis of pulmonary embolism can improve the knowledge of pulmonary embolism,and further improve the accuracy of CT diagnosis to guide clinical practice.
