| 摘 要： | 目的:探讨双源CT血管成像(DSCTA)在主动脉缩窄诊断中的应用。材料和方法:对临床怀疑主动脉缩窄患者15例进行双源CT主动脉增强扫描,将获得的数据进行容积再现(VR)、多平面重建(MPR)、最大密度投影(MIP)、曲面重建(CPR),分析主动脉走行及心内外结构特征。结果:15例患者均诊断为主动脉缩窄,DSCTA图像显示了主动脉缩窄的部位、程度及侧支血管情况。15例中单纯性主动脉缩窄6例,复杂性主动脉缩窄9例,其中伴动脉导管未闭8例,室间隔缺损5例,房间隔缺损4例,肺动脉高压3例,主动脉弓发育不良2例,主动脉瓣合并二尖瓣畸形、主动脉左弓右降、左室流出道与主动脉瓣间局限性膨大各1例。结果与手术及数字减影血管造影(DSA)检查结果相一致。结论:双源CT血管成像方便、快捷、无创,是诊断主动脉缩窄重要方法。

| Abstract: | Purpose To explore the value of dual-source CT angiography(DSCTA)in the diagnosis of coarctation of aorta(CoA).Materials and Methods 15 patients with suspected CoA were examined with DSCTA.Then the source images were post processed using volume rendering(VR),multiple planar reformation(MPR),maximum intensity projection(MIP)and curved planar reformation(CPR),and sequential segmental analysis of the intracardiac and extracardiac anomalies was performed.Results All 15 patients were diagnosed as CoA by DSCTA.Th... |
