Fig. 1From: Quantification of mitral regurgitation in patients with hypertrophic cardiomyopathy using aortic and pulmonary flow data: impacts of left ventricular outflow tract obstruction and different left ventricular segmentation methodsSchematic illustration of the four different methods of MRvol quantification used. Representative images of two left ventricular segmentation methods (incl vs. excl) (top). End-diastole and end-systole are shown. Top, left: Papillary muscles and trabeculations were included (incl) in the blood pool, while they were excluded from the ventricular mass calculations. Top, right: Papillary muscles and trabeculations were excluded (excl) from the blood pool, with mass calculations performed separately for ventricular walls and papillary muscles/trabeculationsBack to article page
