摘要
目的:探讨多排CT肺动脉造影(MSCTPA)对高原红细胞增多症合并肺动脉栓塞的诊断价值。方法:对4例高原红细胞增多症并肺动脉栓塞的患者进行16排CT肺动脉血管造影扫描,图像采用扫描层厚1mm,重建间隔为0.8mm,注射速率采用4.0mL/s获得容积数据进行MIP及VR重建。结果:4例均能显示部位,肺动脉及其分支均有单支或多支栓塞,3例有胸腔积液,1例有肺梗塞,1例有心包积液。结论:高原红细胞增多症是高原地区肺动脉栓塞的重要原因之一,MSCTPA是明确诊断高原地区肺动脉栓塞的首选方法。
objective:To evaluate the effect of muliti-slice spiral CT pulmonary angiography(MSCTPA)in diagnosis of pulmonary embolism combined with high altitude polycythemia.Methods:4 patients with pulmonary embolism combined with high altitude polycythemia were examined by MSCTPA,The reconstruction was conducted with 1.0mm slices,reconstruction intervals of 0.8mm and injection rates of 4mL/s before operations.And the three-dimension reconstruction of maximum intensity projection (MIP) and volume rendering (VR) were reconstructed by acquired volume data.Results:4 cases could show and involved with pulmonary embolism in pulmonary artery or branches.Of them,3 cases had pleural effusion,1 case of pulmonary infarction.Conclusions:MSCTPA could be the first choice for diagnosis of pulmonary artery embolism at high altitude.
