目的 探讨时间密度曲线技术在 肺动脉上的应用价值。方法 利用PHILIPS IngenuityCT其在肺动脉栓塞(pulmonary embolism,PE)检查上所特有的时间-密度 (Test Injection)曲线技术监测肺动脉， 所得肺动脉图像请副高级别诊断医师判定 级别并对结果进行分析讨论。结果 965例 患者增强扫描后，增强效果优者917例， 占95%，一般者34例，占3.0%，14例失 败，占1.5%；结论 可知时间-密度曲线 技术肺动脉增强所得图像具有临床诊断价 值。

Objective To study the time density curve technology application value in the pulmonary artery. Methods Using the PHILIPS IngenuityCT in pulmonary embolism (pulmonary embolism, PE) peculiar to check on the time-density (Test Injection) curve technology monitoring pulmonary artery, the pulmonary artery image please subtropical high level in the diagnosis of doctors to determine the level and the results are analyzed and discussed. Results 965 cases of patients after enhancement scanning, the enhancement effect of instituting of 917 cases (95%), 34 cases, generally accounted for 3. 0%, 14 cases of failure, accounted for 1.5%. Conclusion Time-density curve technology pulmonary artery to enhance the image with the clinical diagnostic value.
