多层螺旋CT血管造影对肺动脉栓塞的诊断价值

目的：评价多层螺旋CT肺血管造影（MSCTPA）在诊断肺动脉栓塞中的作用及价值。方法：对临床怀疑肺动脉栓塞（PE）经CTP明确诊断的30例患者进行回顾性分析。结果：30例患者累及70处肺动脉及其分支，直接征像为部分性充盈缺损。附壁性充盈缺损，中心性充盈缺损即轨道征。完全阻塞；间接征像为局限性肺纹理稀疏，肺动脉高压，右心扩大，胸腔积液，肺梗死灶。结论：多层螺旋CT血管造影对肺梗死能及时、正确诊断肺动脉栓塞，是安全、无创、快捷的诊断方法。

Value of 16-MSCTPA in the diagnosis of pulmonary embolism

Objective To evaluate the effectiveness and value of MSCTPA in the diagnosis of pulmonary embolism (PE).MethodThe regressive analysis was made on 30 patients who were clinical suspicious of PE diagnosed by CTP clearly.ResultsThirty patients involved in 70 pulmonary arteries and their branches.Direct signs:partial filling defect;mural filling defect;central filling defect that is track symptoms.lndircet signs:the limitations of lung markings sparse,pulmonary hypertension,expanding the right heart,pleural effusion and the focus of pulmonary infarction.ConclusionMSCTPA can diagnose pulmonary infarction timely and correctly manner which is a safe,non-invasive and quick diagnostic method.
