Abstract:
Objective To explore the accuracy and feasibility of dual-source CT(DSCT)in evaluating the left ventricular function compared with echocardiography.Methods 30 cases of coronary heart disease were continuously collected in our hospital ,and dual-source CT and echocardiography were examined in a week.Left ventricular function parameters (LVEDV,LVESV,LVSV)were measured,and paired sample t test was compared to show whether there was any difference between the two methods,Rates betweengroups were compared with Chi-square test,Pearson correlation analysis method was applied to calculate the correlation between the two methods.Results There was no statistically significant difference for LVEDV,LVESV,LVSV,LVEF parameters between the two methods (t test,P >0.05).By Pearson test,the correlation coefficient was r=0.770-0.938(P <0.05),in which the high relation between the two methods was showed.Conclusion A strong accuracy of dual-source CT in evaluating left ventricular function is demonstrated.Dual-source CT angiography is a noninvasive assessment of coronary tree,whereas the analysis of the left ventricular parameters provides additional information of cardiac function without further radiation exposure or scan time,which can provide a more intuitive and system information for clinical.
