Abstract Objective: To evaluate the feasibility and accuracy of coronary angiography and left ventricular function analysis evaluated by 64-slice computed tomography simultaneously. Methods: Fifty consecutive patients suspected or diagnosed with coronary disease were examined by retrospective electrocardiogating(ECG) cardiac CT scan for coronary artery angiography and left ventricular functional analysis. Coronary artery was divided into 16 segments according to the American Heart Association. The image quality was graded with 4-points scale. The LVEF (left ventricular eject function) was calculated from cardiac CT date and compared with ultrasonic cardiogram by pearson correlation. Results: Forty-three patients accomplished CT examination successfully, in whom, thirty-five cases finished ultrasonic cardiogram also. In 508 evaluated coronary segments, 91.93% could be diagnosed. The LVEF correlation of CT and ultrasonic cardiogram was high (r=0.64). Conclusion: The 64-slice CT can be used in coronary angiography and left ventricular function analysis simultaneously with high imaging quality of coronary artery and reliable analysis of left ventricular function.
