Table 2 Results from applying the correction described in Eq. (11) to DVR values obtained from Logan ref. and [18F]MNI-659. When the slope of the Bland-Altman plot ≠0, no average difference can be calculated due to proportionality bias

From: Revisiting the Logan plot to account for non-negligible blood volume in brain tissue
