| 摘 要： | 目的：评价256层螺旋CT对左心耳定量测量的可重复性.方法：随机选取我院50例行常规冠脉CTA扫描患者,将原始扫描数据行75％期相重建,于工作站对左心耳开口长短径、面积、容积等参数进行测量.比较各参数在同一观察者不同时间及不同观察者间测定的可重复性.结果：同一观察者不同时间测定的各参数结果比较,差别无统计学意义（P＞0.05）;不同观察者两次测定的各参数结果进行比较,差别亦无统计学意义（P＞0.05）.结论：利用Philips 256 MSCT冠脉成像对左心耳进行定量测量有较高的可重复性和一致性,可以为临床房颤射频消融术及左心耳封堵术提供重要参考. |

| Abstract: | Objective：To assess the reproducibility of the quantitative measurement of left atrial appendage （LAA） using 256-slice spiral CT.Methods：In the population of patients referred to our hospital for 256 MSCT coronary angiography,50 individuals were randomly selected.The images from 75％ of the cardiac cycle were reconstructed and then sent to the workstation for measuements of the longitudinal and transverse diameters of LAA orifice,the area of LAA orifice,LAA volume,et al.Inter-observer and intra-observer reproducibility were evaluated.Results：There was no significant difference between the results from two different observers or between the results at different time points for the same observer （P＞0.05）.Conclusion：Philips 256 MSCT coronary angiography shows high reproducibility and agreement in measuring the LAA parameters,which can provide important reference for clinical ablative treatments and the elimination of the LAA. |
