Abstract: 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. Method Cardiac function tests were performed on 10 pairs of normal and heart failure rats by micro-CT, aortic intubation, and ultrasound. Left ventricular function parameters were measured using cardiac function analysis software: end-systolic volume, end-diastolic volume, and ejection fraction. The micro-CT result were compared with the result of aortic intubation and echocardiography. Result All the rats were examined by micro CT, aortic catheterization and echocardiography. There was a good correlation between the parameters of left ventricular function measured by micro CT, aortic catheterization and echocardiography. Conclusion micro-CT can be used to evaluate left ventricular function and is a feasible solution for accurate measurement of ventricular function.
