目的 探讨64层螺旋CT非门控技术在心房颤动患者左心房-肺静脉成像中的应用价值.方法 回顾性分析2015年9月至2017年12月127例心房颤动行射频消融术治疗患者的临床资料.其中,使用非门控技术扫描107例（非门控技术组）,使用门控技术扫描20例（门控技术组）,利用容积再现（VR）重组技术进行后处理,观察左心房及肺静脉的解剖结构.结果 非门控技术组左心房充盈良好101例,充盈尚可4例,充盈欠佳2例;门控技术组充盈良好18例,充盈尚可2例,两组左心房图像质量比较差异无统计学意义（P〉0.05）.107例非门控技术组患者中,标准4支肺静脉90例（84.1％）,变异肺静脉17例（15.9％）.结论 64层螺旋CT非门控技术能较好显示左心房-肺静脉的解剖结构,能为心房颤动射频消融术治疗提供有价值的信息.
Objective To evaluate the value of non-gated 64 multi-slice CT in left atrium and pulmonary vein imaging. Methods The clinical data of 127 patients with atrial fibrillation who had underwent radiofrequency catheter ablation from September 2015 to December 2017 were retrospectively analyzed. Among them, non- gated technique scanning was used in 107 cases （non- gated technique group）, and gated technique scanning was used in 20 cases （gated technique group）. The volume rendering （VR） of post-processing technique was used to observe the anatomic structures of the left atrium and pulmonary vein. Results In non-gated technique group, there were 101 cases with good left atrial filling, 4 cases with acceptable filling and 2 cases with poor filling; in gated technique group, there were 18 cases with good left atrial filling and 2 cases with acceptable filling. There was no statistical difference in the image quality of left atrium between 2 groups （P〉0.05）. Among 107 patients of non- gated technique group, the standard type of 4 pulmonary veins was in 90 cases （84.1%）, and the variation of pulmonary veins was in 17 cases （15.9%）. Conclusions The anatomic structures of pulmonary veins and left atrium could be displayed clearly in non-gated 64 multi-slice CT with reconstruction techniques, which has important value in the guidance of radiofrequency catheter ablation for treatment of atrial fibrillation.
