摘　　要：目的通过分析CT平扫血栓的密度(CT值)、血栓CT值与时间相关性及阻塞血管直径、形态变化,提高CT平扫对肺栓塞的早期诊断率。方法经临床手术、CT增强、DSA证实,回顾性分析27例的急性肺栓塞病例CT平扫时表现。结果急性肺栓塞在CT平扫时呈现血栓高密度,相应血管管径增粗,且血栓密度(CT值)与发病时间相关联。结论CT平扫可提高急性肺栓塞的诊断率。Objective By analyzing the density of thrombus in CT plain scan （ CT number）, the Correlation between CT number and time, and the Diameter and shape of Blocked blood vessels, to improve the rate of diagnosis in acute pulmonary embolism by CT plain scan. Methods The plain CT findings of 27 cases of acute pulmonary embolism were retrospectively analyzed, which were confirmed by clinical operation, CT contrast enhanced scan or DSA. Results Acute pulmonary embolism was shown a high density of thrombus in CT plain scan, the diameter of the blood vessel was widened, and the thrombus density （ CT number） was correlated with the thrombus duration. Conclusion CT plain scan can improve the diagnostic rate of acute pulmonary embolism.
