Abstract

Abstract

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.
