Fig. 3From: A strategy to account for noise in the X-variable to reduce underestimation in Logan graphical analysis for quantifying receptor density in positron emission tomographyComparisons of the percentage bias and variability in the estimated BPND values. The percentage bias and variability in the BPND estimated from the noisy tTACs by LSC, MRTM2, and the conventional LGA, are compared for the 11 values of true BPNDBack to article page
