摘　　要：目的评价多层螺旋CT成像诊断急性肺栓塞的价值,从而为急性肺栓塞精准诊断提供参考依据。方法以2019年1月—2023年10月经病理确诊的102例急性肺栓塞病例作为研究对象,采用GE 64排螺旋CT扫描仪进行中央和节段肺动脉CT扫描。以病理学检查结果为金标准,评价多层CT成像诊断急性肺栓塞的效果。结果102例经病理学检查确诊的急性肺栓塞病例中,经多层CT成像诊断为急性肺栓塞92例,诊断符合率为90.20%(92/102),其中左侧肺动脉栓塞17例(18.48%)、右侧肺动脉栓塞31例(33.70%)、两侧肺动脉均栓塞44例(47.82%)。经多层CT成像共显示肺动脉9905支,其中304支肺动脉检出栓塞,总体栓塞率为3.07%,其中肺叶动脉栓塞率最高(43.89%)。结论多层螺旋CT成像诊断急性肺栓塞准确率高,可直观、清晰显示患者肺动脉栓塞情况,值得临床推广应用。Objective To evaluate the value of multi-slice spiral computed tomography(CT)for diagnosing acute pulmonary embolism,and to provide a reference for the precise diagnosis of acute pulmonary embolism.Methods We enrolled a total of 102 patients pathologically diagnosed with acute pulmonary embolism from January 2019 to October 2023.All the patients underwent CT scanning of central and segmental pulmonary arteries with a GE 64-slice spiral CT scanner.The diagnostic efficacy of multi-slice CT scans for acute pulmonary embolism was evaluated with the pathological results as the gold standard.Results Of the 102 patients pathologically diagnosed with acute pulmonary embolism,multi-slice CT detected 92 cases,with an accuracy of 90.20%(92/102),including 17 cases(18.48%)of embolism in left pulmonary arteries,31 cases(33.70%)of embolism in right pulmonary arteries,and 44 cases(47.82%)of embolism in both pulmonary arteries.Multi-slice CT visualized a total of 9905 pulmonary artery branches,and 304 of them(3.07%)had embolism,with the highest embolism rate in lobar arteries(43.89%).Conclusion Multi-slice spiral CT has high accuracy for diagnosing acute pulmonary embolism by directly and clearly visualizing embolism in the arteries of the lungs,which deserves clinical promotion.
