摘要
目的:比较双源CT(Dual-source CT,DSCT)和超声心电图对左心功能的评估,探讨DSCT在定量评估左心功能方面的准确性及可行性。方法:对31例临床确诊或疑似冠状动脉粥样硬化心脏病患者行双源CT冠状动脉成像和超声心电图检查,分别测得左心室收缩末期容积、舒张末期容积及左室射血分数值,并进行统计学分析。结果:双源CT和超声心电图所测得的各组左心功能数据相关性高(r值=0.70～0.87)。结论:双源CT冠状动脉成像检查不但可以分析冠状动脉疾病,同时也可以定量评估左心功能。
Objective：To explore the accuracy and feasibility of dual source CT （DSCT） in evaluating the left ventricular function through comparing left ventricular volume data obtained by DSCT with data gained by echocardiography. Methods：Thirty-one patients with known or suspected coronary artery disease （CAD） underwent DSCT and then echocardiography within 48h. The left ventricular functions which included left ventricular end systolic volume （LVESV） ,left ventricular end diastolic volume （LVEDV） and left ventricular ejection fraction （LVEF） were determined by using these two modalities. Statistical analysis including Pearson correlation coefficient was carried out, Results： A strong correlation between DSCT and echocardiography （r= 0.70 - 0.87） was found for all parameters. Conelusion..DSCT angiography is a noninvasive assessment of coronary tree.whereas the analysis of the left ventricular parameters provides additional information of cardi- ac function without further radiation exposure or scan time.
