肺动脉造影与核素肺灌注/通气扫描在肺栓塞诊断价值相关性研究

目的 :探讨选择性肺动脉造影与核素肺灌注 通气扫描在肺栓塞诊断的相关性。方法 :回顾性分析 2 3例肺栓塞选择性肺动脉造影与核素肺灌注 通气扫描显像。结果 :2 3例选择性肺动脉造影与核素肺灌注 通气扫描显像结果比较 ,肺血管堵塞≥ 8支以上者 ,二者相关性达 10 0 % ;<8支者二者相关性为 90 5 %。 7例冠状动脉造影阴性患者 ,经肺动脉造影证实为肺栓塞。结论 :选择性肺动脉造影是临床肺栓塞诊断和病变定位的可靠依据 ,而核素肺灌注 通气扫描显像检查则是目前临床诊断肺栓塞的有价值的无创性诊断方法之一。

Interrelation study on pulmonary angiogram and radionuclide imaging in patients with pulmonary embolism

Objective:This study is to compare the pulmonary angiography and radionuclide imaging in patients with pulmonary embolism.Method:Pulmonary angiography and radionuclide imaging were analyzed in 23 patients with suspected pulmonary embolism.Result:When pulmonary vessel were obstructed more than 8 branches the coincidence rate between pulmonary angiography and radionuclide imaging was 100%.For less than 8 branches cases,the coincidence rate was 90.5%.Coronary angiogram showed negative in 7 patients,whose pulmonary angiography displayed pulmonary embolism.Conclusion:Pulmonary angiography is the reliable basis of pulmonary embolism diagnosis and lesion location,but pulmonary perfusion/ventilation scan is the most valuable non-invasive method in the diagnosis of pulmonary embolism.
