Fig. 3From: Direct measurement of atrioventricular valve regurgitant jets using 4D flow cardiovascular magnetic resonance is accurate and reliable for children with congenital heart disease: a retrospective cohort studyBland Altman plots comparing the 4 methods in this study: the indirect methods (VOL and both AIMs) and the direct method (JET). The limits of agreements (dashed lines) are narrower for the JET comparisons (c-e) than for the VOL comparisons (a-c). The mean difference is shown as a solid line. Mitral regurgitation (MR) is denoted by red points, tricuspid regurgitation (TR) is denoted by blue points. VOL = volumetry method, AIMstat = annular inflow method by static plane, AIMtrack = annular inflow method by valve-tracking plane, JET = direct measurement of jetBack to article page
