Inter-model reproducibility of [11C]HED PET measurements of VT using MA1 (a, b) and Logan (c, d) models. Scatter-plots (a, c) show excellent correlation of the graphical model values versus the 1TC standard with R2 > 0.95. Bland Altman plots (b, d) show the 95% limits-of-agreement (dotted lines) and confidence intervals (shaded areas) at Delta = mean ± 1.96 × SD. [Values] are Delta = median ± 1.45 × IQR, p value assessed by the Wilcoxon Signed Rank Test
