肺动脉血栓栓塞症(肺栓塞)是体静脉和右心系统血栓栓子脱落堵塞肺动脉引起肺循环障碍的临床和病理生理综合征。是发病率高、病死率高及误诊率高的重要心肺疾病。肺动脉造影是诊断肺栓塞的金标准。螺旋CT,特别是多排螺旋CT肺动脉造影(MDCPTA)已被认为是肺栓塞的首选检查方法。但
Pulmonary thromboembolism (pulmonary embolism) is a clinical and pathophysiological syndrome of impediment to pulmonary circulation that clogs the pulmonary arteries by the shedding of thromboemboli in the systemic and right ventricular systems. It is an important cardiopulmonary disease with high incidence, high fatality rate and high misdiagnosis rate. Pulmonary angiography is the gold standard for the diagnosis of pulmonary embolism. Spiral CT, especially multi-slice spiral CT pulmonary angiography (MDCPTA) has been considered the preferred method of detection of pulmonary embolism. but
