摘　　要：本研究拟确定利用超声心动图诊断肺栓塞（PE）的灵敏性和特异性。研究包括两个阶段。首先600例患者入选接受超声心动图测定双侧肺血流。利用多层CT检查，200例被诊断为肺动脉高压，100例为PE。其他300例无心肺疾患的受试者被作为对照。测定双侧肺动脉的时间-流速积分（TVI）和血流体积。对照组、肺动脉高压组和PE组的双侧肺动脉TVI差异比率（△TVI／平均值）分别为12．0％±9．3％、13．8％±12．1％和38．6％±14．9％。对照组、肺动脉高压组和PE组的双侧肺动脉血流差异比率（△血流／平均值）分别为15．1％±11．7％、17．6％±14．9％和36．8％±17．5％。The present study was undertaken to determine the sensi- tivity and specificity of echocardiography in the diagnosis of pulmonary embolism（PE） The study consisted of 2 stages. First, 600 patients were enrolled to measure bilateral pulmonary blood flow by echocardiography. Using muhidetector row computed tomography, 200 diagnosed with pulmonary hypertension and subjects were 100 with de- fined PE. Another 300 subjects without cardiopulmonary distress served as controls. The time-velocity integral（TVI） and flow volume of both pulmonary arteries were obtained. The percentage differences in bilateral pulmonary arterial TVI（ATVI/mean） were 12.0±9.3%, 13.8±12. 1%, and 38.6± 14. 9% for controls, subjects with pulmonary hypertension, and subjects with PE. respectively.
