Validation of gating in healthy male adults. (a) Representative through-plane velocity curves from the DAo where red and blue are pulse-gated and MOG reconstructions, respectively. The shading represents the variation across the repeats in the subject. (b) Bland-Altman plots of the mean (bias = − 0.32 cm/s, limits of agreement [− 3.6, 2.9] cm/s) and peak (bias = − 1.4 cm/s, limits of agreement [− 9.2, 6.4] cm/s) through-plane velocities measured at the DAo from the pulse-gated and MOG CINEs are shown. The different colors in b represent data from the different subjects. The solid blue line represents the bias and the dotted lines show the limits of agreement
