摘要 目的:探讨东芝320排CT冠状动脉容积扫描后选取最佳时相传至东芝vitrea2.1工作站,结合多种后处理重建技术对左心房及肺静脉的正常结构,异常结构的研究。方法:选取我院2019年1月―2019年6月房颤患者拟射频消融术治疗并术前冠脉CTA检查60例,选取最佳实相传至东芝vitrea进行Aixal、MPR、VR等多种后处理三维技术对肺静脉、左心房形态学结构的观察。结果:1.房颤患者肺静脉标准型占76.7%,左肺静脉共干是房颤患者中变异最多的占13.3%。2.肺静脉口的大小随整个心动周期的变化而变化,其中心脏收缩期肺静脉口最大,舒张期肺静脉口最小。3.螺旋CT对房颤患者左心房血栓敏感高。结论:左房及肺静脉三维重建为射频消融术前提供更多直观明了的解剖信息,大大的缩短了手术及x线曝光时间,减少了辐射剂量及术后并发症。
