摘要
目的探讨多层螺旋CT肺动脉造影在肺栓塞诊断中的临床应用。方法19例肺动脉栓塞患者采用MSCT增强扫描,进行多平面重建(MPR)和最大密度投影(MIP)重建处理并计算CT肺动脉阻塞百分数。结果多层螺旋CT扫描肺动脉主干、左右肺动脉及叶、段、亚段动脉显示良好,显示受累肺动脉122支,其直接征象为肺动脉血管内充盈缺损,间接征象包括肺梗死、肺野少血征、胸腔积液等。CT肺动脉阻塞百分数分别从2.5%到75%不等。结论多层螺旋CT能清楚地显示肺栓塞的形态、发生部位及其他间接征象,为临床治疗提供帮助。
Objective To explore the application of pneumoangiography with multi-slice CT(MSCT)in the diagnosis of pulmonary embolism(PE).Methods Nineteen cases with PE were proved with MSCT contrast enhancement scanning,and processed multiple planar reconstruction(MPR)or maximum intensity projection(MIP),and then the percent of PE CT index(CTI%)was calculated.Results Main pulmonary trunk,left or right pulmonary branch,and lobar,segmental or subsegmental pulmonary artery were displayed well with MSCT,122 branches were ...
