Fig. 5From: 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 intra- and inter-observer reliability measurements (a-d and e-h, respectively) using the indirect and direct methods measuring atrioventricular valve regurgitation. Mean difference is represented with a solid line; limits of agreement are represented with dashed lines. 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
