Bland–Altman plots between Observers 1 and 3 for (A) pix technique and the smaller homogeneous ROI, (B) pix technique using the full vessel ROI and (C) nbr− technique and full vessel ROI. All three plots demonstrated a tighter clustering for lower T2* values between 15 and 40 ms. Despite attempts to avoid error prone voxels with the pix technique, the smaller homogeneous ROI still resulted in a wide confidence interval of 18ms only slightly improved over the fully vessel ROIs interval of 24 ms. The nbr− method yielded both a shorter range of values as well as significantly narrower confidence interval of only 7 ms.
