Volumetric method for the measurement of right ventricular function. Contiguous 8 mm thick slices of the ventricles (right ventricle [a] and left ventricle [b]) in dynamic short-axis allow precise measurement of end-diastolic (bottom left) and matching end-systolic (bottom right) endocardial areas. Modified Simpson’s rule allows the measurement of end-diastolic and end-systolic volumes, and the precise calculation of ejection fraction
