MSCT肺血管造影在肺动脉栓塞诊断中的应用

The application of pneumoangiography with MSCT in the diagnosis of pulmonary embolism

目的:探讨MSCT肺血管造影在肺动脉栓塞诊断中的应用。方法:10例肺动脉栓塞患者采用MSCT增强扫描,并进行多平面重建结果:应用16排螺旋CT扫描主肺动脉、叶肺动脉、段、亚段动脉显示良好,显示受累肺动脉72支,其直接征象为肺动脉充盈缺损,间接征象包括肺梗死、肺少血征、胸腔积液。结论:16层螺旋CT能清楚地显示肺栓塞的直接征象及间接征象,及时发现和诊断肺栓塞。

Objective：To explore the application of pneumoangiography with MSCT in the diagnosis of PE. Methods： 10 cases with PE were proved with MSCT contrast enhancement scanning, and processed MPR.Results：Main pulmonary, interlobar pulmonary, segmental pulmonary and subsegmental pulmonary artery were displaged well with 16 row sprial CT, 72 branches were displayed, direct signs is pulmonic filling-defect, indirect signs include plumonary embolism, lung lack of blood, pleural effusion. Conclusion：The direct and indirect signs of PE can be showed clearly with 16 row spiral CT, found in time and diagnosed correctly.
