Abstract：Objective: To discuss the influence of different reconstruction methods of 64-slice CT quantitative assessment of left ventricular pump function. Methods: We collected 100 cases of patients with coronary artery CTA images data. All the patients respectively underwent coronary CTA examination and the reconstruction of the left ventricular function by two different methods(Segmentation and Simpson). Correlation of the two different reconstruction methods in evaluating left ventricular function(LVESV, LVEDV, LVSV, LVEF) was analyzed. Then the average reconstruction time of the two different CT reconstruction methods was compared. Results: The two different reconstruction method for the measurement of LVESV, LVEDV, LVSV, LVEF were highly correlated(r>0.900, P<0.01), and the values of them measured by two different methods were similar with no statistical differences. The reconstruction time of the Segmentation method(3 min45 s±23 s) was significantly shorter than the Simpson method(9 min58 s±47 s). Conclusion: The study shows that two kinds of different CT reconstruction methods in analysis of left ventricular function had high correlation. The Segmentation method in clinical application can greatly reduce the time, improve work efficiency, and minimize the influence of the operator’s subjective factors.
