Bland–Altman plot of difference in aortic calcification volume against mean calcification volume. Difference in calcification volume = radial volumetric interpolated breath-hold examination (radial-VIBE) minus CT volume. The linear regression equations for bias and its estimated regression based 95% limits of agreement (LOA) are on the top right. Blue solid line represents bias; green-dashed lines are the estimated regression based 95% LOA; black-dashed lines are the crude 95% LOA
