This abstract presents a method for computing right-ventricular volume-versus-time curves and peak ejection and filling rates from standard cardiac cine MRI. The method uses RV contours drawn semi-automatically near end-diastole and end-systole and propagates them to the remaining time frames via a non-rigid registration technique. The propagated contours are validated by comparing them to contours manually drawn by a cardiologist with Level 3 training. In addition, peak ejection and filling rates computed from both manually-drawn and propagated contours are compared.
