The PET image in baboon summed from time of injection through 90 min for (A) 2-11C-2 (injected dose = 2.96 mCi), (B) 11C-3 (injected dose = 3.42 mCi), and (C) 11C-4 (injected dose = 3.27 mCi). Ketamine hydrochloride (10 mg/kg) was used as an anesthesia by an intramuscular injection. We note that the distribution of 4-11C-2 is not shown as the images do not differ between 4-11C-2 and 2-11C-2.
