Fig. 3From: Characterization of point-spread function specification error on Geometric Transfer Matrix partial volume correction in [11C]PiB amyloid imagingGTM operating point characteristics showing GTM fractional error plotted as a function of GTM-corrected [11C]PiB SUVR. A fit to the data, described in the text (equation 2), is included to highlight the trend of the data. Vertical lines show the University of Pittsburgh thresholds for amyloid positivity for GTM-corrected data for each regionBack to article page
