摘　　要：目的探讨肺栓塞与肺梗死的影像学诊断价值。方法对２０例临床疑诊为肺动脉栓塞（其中５例合并肺梗死）的病人进行了胸部Ｘ线平片、核素肺灌注扫描和数字减影肺动脉造影诊断对比。结果数字减影肺动脉造影阳性发现１０例，以此为金标准，胸部Ｘ线平片检查，敏感性４２．９％，特异性３３．３％；核素肺灌注扫描检查，敏感性７２．７％，特异性７７．８％。结论胸部Ｘ线平片、核素肺灌注扫描可作为肺动脉栓塞的首选诊断方法，而数字减影肺动脉造影是肺动脉栓塞最明确的诊断方法，但有创伤性。Objective To assess the diagnostic value of three imaging diagnostic methods in diagnosis of pulmonary embolism and infarction. Methods Three diagnostic imaging methods (Xray, ventilation perfusion scanning and pulmonary angiography) were compared and evaluated on the basis of 20 patients suspected of pulmonary embolism and infarction. Results 10 of the 20 cases were positive as diagnosed by pulmonary angiography, using this as the diagnostic standard, the sensitivity and specificity are 42.86% and 33.33% for Xray examination, and 72.72% and 77.78% for ventilation perfusion scanning. Conclusions Xray and ventilation perfusion scanning are the methods of first choice for diagnosis of pulmonary embolism, while pulmonary angiography is the most reliable method. Being invasive the latter will be used only when pulmonary embolism is highly suspected and difficult to determine with other methods.
