双源CT左心功能分析与超声心动图的对比研究

Comparative study of left ventricular function using dual-source CT and echocardiography

目的探讨双源CT与超声心动图对左心功能分析结果的一致性。方法收集新疆医科大学第五附属医院2016年1~12月符合纳入标准的患者30例,同一患者在一周内完成双源CT及超声心动图的左心功能检查,使用双源CT心功能分析软件,测量左室收缩末期容积(ESV)、舒张末期容积(EDV)、每搏输出量(SV)、射血分数(EF),获得相应结果,与超声心动图的指标进行对比研究及统计分析。结果双源CT及超声心动图的EDV、ESV、SV和EF等相关指标比较,双源CT测量指标略大于超声心动图,但各指标之间相关性较好,差异均无统计学意义(P>0.05)。结论双源CT在左心功能评价方面与超声心动图指标相关性高,有较好的一致性。

Objective To explore the consistency of the results of left ventricular function between dual-source CT and echocardiography. Methods A total of 30 cases in accordance with the inclusion criteria were collected from the Fifth Affiliated Hospital of Xinjiang Medical University from January 2016 to December 2016. Every case was per-formed the left ventricular function examination with both the dual-source CT and echocardiography within a week. Through the heart function analysis software of dual CT, left ventricular end systolic volume （ESV）, end diastolic vol-ume （EDV）, stroke volume （SV） and ejection fraction （EF） were measured and the appropriate results were compared with the indexes of echocardiography, and statistical analysis was carried out. Results The relevant indicators, includ-ing EDV, ESV, SV, EF of dual-source CT and echocardiography were compared, and the measurement of dual-source CT was slightly larger than the measurement of echocardiography. However, these relevant indicators had good correlation without significant difference （P〉0.05）. Conclusion Dual-source CT can be used to evaluate left ventricular function as well as echocardiography.
