From: Comparison of four 11C-labeled PET ligands to quantify translocator protein 18 kDa (TSPO) in human brain: (R)-PK11195, PBR28, DPA-713, and ER176—based on recent publications that measured specific-to-non-displaceable ratios

Time-stability analysis. Total distribution volume (V T) of 11C-(R)-PK11195 (□), DPA-713 (▼), and ER176 (●) obtained from low affinity binders (LABs) plotted as a function of duration of image acquisition. V T from each scan duration is normalized as percentage of V T over 90 min of imaging
