Abstract：Objective Based on CSRT tracking algorithm,the left atrioventricular plane displacement velocity curve was cal-culated,the correlation with echocardiographic E/A ratio was analyzed.Methods Retrospective analysis was performed on 68 patients who underwent cardiac magnetic resonance examination.Based on CSRT tracking algorithm,atrioventricular plane dis-placement was calculated,and the atrioventricular plane displacement velocity curve was obtained by derivation.The correlation of E/A ratio between atrioventricular plane displacement velocity curve and Doppler flow spectrum was analyzed.Results The atrioventricular plane displacement velocity curve based on cardiac magnetic resonance imaging showed S,E and A waves consis-tent with echocardiography.The E/A ratio of left atrioventricular plane displacement velocity curve was moderately correlated with echocardiographic(r=0.67,P<0.001).Conclusion The left atrioventricular plane displacement velocity curve shows the potential value of quantitative evaluation of cardiac function.
