Figure 5
A Bland-Altman plot representing the intra-observer variability of the macro-parameters K i and Patlak's slope. The test-retest error is plotted as a function of the average [18F]FCho influx across the cell membranes. Black dots represent data points from the 3C2i; the black dash-dotted lines represent 95% confidence interval. The grey dots represent data points from the 2C1i; the grey lines represent 95% confidence interval. The black crosses represent data points from the Patlak plot; the black dotted lines represent 95% confidence interval.
