摘　　要：目的探讨64排CT肺动脉造影及后处理技术在肺栓塞中的应用及诊断价值。方法选取无锡市第五人民医院2017年6月~2019年12月的31例肺栓塞患者作为研究对象,使用西门子64排CT轴位增强扫描,再利用原始数据进行后处理重建,包括多平面重建(MPR)、最大密度投影(MIP)和容积重建法(VR),对图像进行分析研究。结果肺动脉栓塞共累及89支各级肺动脉,直接征象表现为血管内完全性和不完全性充盈缺损,间接征象为肺的楔形实变、肺内渗出影以及肺动脉主干增粗、右心室增大及胸腔积液等。结论采用64排CT诊断肺栓塞具有较高的应用及诊断价值。Objective To explore the application and diagnostic value of 64-slice CT pulmonary angiography and post-processing technique in pulmonary embolism.Methods A total of 31 patients with pulmonary embolism in Wuxi Fifth People′s Hospital from June 2017 to December 2019 were selected as the research objects.Siemens 64 slice CT axial enhanced scanning was used,and the original data were used for post-processing reconstruction,including multiplanar reconstruction(MPR),maximum density projection(MIP)and volume reconstruction(VR),and the image was analyzed and studied.Results There were 89 pulmonary arteries involved in pulmonary embolism.The direct signs of pulmonary embolism were intravascular complete and incomplete filling defect.The indirect signs were pulmonary wedge consolidation,pulmonary exudate,enlargement of the main pulmonary artery,enlargement of the right ventricle and pleural effusion.Conclusion 64-slice CT has high application and diagnostic value in the diagnosis of pulmonary embolism.
