Bland-Altman plots of the difference versus mean for the 3D and 2D intracranial vessel wall CMR paired intracranial vessel wall and lumen measurements show good agreement with a small bias of 2.4 mm3, 3.0 mm3, 0.002, 0.02 mm, and 0.04 mm for lumen volume (a), vessel wall volume (b), normalized wall index (c), mean wall thickness (d) and maximum wall thickness (e), respectively. The solid lines represent the mean difference, and the dashed lines indicate the 95% limits of agreement. SD = standard deviation
