摘　　要：目的探讨CT肺叶血流分布造影在肺栓塞的诊断的可行性。方法利用显影剂的显影效能,采用技巧处理图像,建立对应的映射机制,通过彩色显影法,观察肺叶血流分布,推测肺部血液灌注情况。结果在注入显像剂后,显像剂随血液流动并通过其显像效率,导致CT图像上CT值发生变化,通过肺部原始CT图影像,可以找到血管栓塞处。显影后彩色图影像的蓝色区块,会出现在栓塞血管末梢处,直接从彩色图来观察栓塞区域,较CTA和核医学分析更容易,且更有效率。结论 CT肺叶血流分布造影是通过彩色图影像的分析,描述肺叶血流分布,对肺栓塞的诊断有辅助作用,值得进一步研究及临床应用。Objective To explore the feasibility of CT pulmonary blood flow distribution in the diagnosis of pulmonary embolism.Methods Using the imaging efficiency of the imaging agent,the corresponding mapping mechanism was established by processing the image with skill.The blood flow distribution of the lung lobe was observed by color development method,and the pulmonary blood perfusion was speculated.Results After the imaging agent was injected,the imaging agent flowed with the blood and passed its imaging efficiency,resulting in changes in the CT value on the CT image.Through the original CT image of the lungs,the embolism can be found.After the development,the blue area of the color map image appeared at the end of the embolized blood vessel.Observing the embolized area directly from the color map was easier and more efficient than CTA and nuclear medicine analysis.Conclusion CT pulmonary blood flow distribution angiography is to describe the blood flow distribution of the pulmonary lobes through the analysis of color map images,and has an auxiliary role in the diagnosis of pulmonary embolism.It is worthy of further research and clinical application.
