Fig. 8From: Accuracy and precision of zero-echo-time, single- and multi-atlas attenuation correction for dynamic [11C]PE2I PET-MR brain imagingEstimated R1 (a) and % bias (b) using Atlas-, ZTE- or MaxProb-MRAC compared to 68Ge-AC for different clusters of brain regions. Bars and whiskers are median, first and third quartile.
