Scatter and Bland-Altman plots. Scatter plots (first column) showing PETSCORES from R1 parametric maps (top), ePIB (20–130 s) (middle), and ePIB (1–8 min) images (bottom) (y-axis), and from FDG SUVR (x-axis). The dashed lines display the identity line. Results of the linear regression are given in boxes at the bottom right corner. Bland-Altman plots (second column) showing the difference between the PETSCORES provided by R1 (top), ePIB (20–130 s) (middle), and ePIB (1–8 min) and FDG SUVR. The full line is at the mean difference value for all scores, and the dashed lines delimit the 95% agreement interval (at mean ± 1.96 × standard deviation). Data are arranged according to subject group: circles represent the AD, triangles the MCI+, squares the MCI−, and cross the HC group
