A Bland–Altman analysis of differences between imaging modalities for FI. For each c-arm angulation, differences between the centerline deviation between FI using the CTA and the MRA data for a 2D-3D registration and b 3D-3D registration were assessed. Means (straight line) and limits of agreement (mean ± 1.96*standard deviation; dashed line) are given. Overall, the spread of values was acceptably small, with the exception of individual values showing differences of > 3 mm using 2D-3D registration. 3D-3D registration was superior to 2D-3D registration regarding both the spread of values and the quality of agreement
