RESUMEN
Objective To investigate the clinical value of dualGsource CT coronary angiography in evaluation of left ventricular function.Methods A total of 5 5 patients with clinically suspected coronary heart disease in our hospital were enrolled.All patients underwent dualGsource CT coronary angiography and ultrasonic cardiogram.The measured values and correlation of the indicators of left ventricular function in dualGsource CT coronary angiography and ultrasonic cardiogram were analyzed.Results Pearson correlation analysis showed that dualGsource CT coronary angiography and ultrasonic cardiogram were highly correlated in left ventricular function measurements (r＝ 0.607－0.840,P＜0.05);The paired sample t test showed that there were no significant differences in the ej ection fraction (EF) and endGdiastolic volume (EDV)between two methods.Conclusion DualGsource CT coronary angiography is reliable in the quantitative evaluation of left ventricular function.The "oneGstop"acquiring of coronary stenosis degree and cardiac function index can provide more diagnostic information to clinic.
