摘要
目的：探讨螺旋CT诊断急性肺动脉栓塞（PE）的方法与价值。材料与方法：回顾性分析249例临床怀疑急性PE的病人资料，探讨螺旋CT肺动脉造影（SCTPA）方法及PE表现特征。结果：测得主肺动脉干强化峰值时间约10.8s；经SCTPA共检出68例PE，发生栓塞的肺动脉705支，其中偏心型506支，占71.8%，中心型147支，占20.8%，附壁型33支，占4.7%，全堵型最少，为19支，占2.7%；181例未发现确切PE征象，但其中105例检出其它疾病。结论：SCTPA是诊断急性PE的重要方法，能较准确地诊断肺内其它病变，对于临床怀疑急性PE的就诊者，SCTPA应作为首选检查。
Abstract
To evaluate the efficacy and technique of spiral CT in the diagnosis of pulmonary embolism(PE). Materials and Methods: Two hundred and forty-nine consecutively registered patients with clinically suspected of PE were analyzed retrospectively. The technique of sprial computed tomography pulmonary angiography(SCTPA) and the appearance of PE were studied. Results: The peak time of enhancement in aorta is about 10.8s. There were 68 patients and 705 pulmonary arteries with embolism, including eccentric embolism in 506 pulmonary arteries(71.8%), centric embolism in 147 pulmonary arteries(20.8%), wall thickened in 19 pulmonary arteries(4.7%) and complete obstruction in 33 pulmonary arteries(2.7%). The other 181 had no PE. But there were other pulmonary lesions found in 105 patients. Conclusion: SCTPA is important in diagnosing PE, and it can detect other pulmonary lesions simultaneously. In patients with clinical suspicion of PE, SCTPA is the primary imaging technique.
