　　Objective To study the consistency and correlation of micro-CT, aortic intubation and echocardiography in measuring left ventricular function parameters, and to evaluate the value of micro-CT in evaluating left ventricular function.

　　Methods 10 pairs of normal and heart failure rats were tested for cardiac function by micro-CT, aortic intubation, and ultrasound. Cardiac function analysis software was used to measure left ventricular function parameters: end-systolic volume, end-diastolic volume and ejection fraction. Compare the results of micro-CT with the results of aortic intubation and echocardiography.

　　Results All 10 examinations of rats obtained results. Micro-CT, aortic intubation and echocardiography have good correlations with left ventricular function parameters.

　　Conclusion Micro-CT can be used to evaluate left ventricular function and is a feasible solution for accurate measurement of ventricular function.
