In the article “Quantification of Translocator Protein (18 kDa) in the Human Brain with PET and a Novel Radioligand, 18F-PBR06,” by Fujimura et al. (J Nucl Med. 2009;50:1047–1053), the legend for Figure 4 was incorrect. The corrected legend appears below. The authors regret the error.
FIGURE 4. Average value of distribution volume (VT) and standard error (SE) in temporal cortex as function of duration of image acquisition using either 300 (A) or 120 (B) min as the terminal point. VT was calculated using unconstrained 2-tissue-compartment model and then averaged for all 9 subjects. Scans were analyzed using brain data from time 0 to specified time on the x-axis. The same data are plotted with a terminal value of either entire 300 min of scanning (A) or only the initial 120 min (B). VT (○) is plotted on the left y-axis. SE(%) (▪) is plotted on the right y-axis.
