Fig. 5

Scatter (a) and Bland-Altman (b, c) plots comparing the VFA and IR techniques at 7 T for healthy (grey circles) and patient subjects (red triangles). The comparison was made both for B₁-corrected (a, c; filled markers) and B₁-uncorrected data (a, b; empty markers). In b) and c), the average bias and limits of agreement are shown as solid and dashed lines, respectively. A poor agreement was seen between the methods, especially without B₁ correction
