PET/MR of 11C-CH3-Orexin A and 11C-raclopride in the brain and nasal cavity after intranasal delivery to the neuroepithelium. (Reprinted from ref. 122. Copyright 2018 American Chemical Society) Comparison of 11C-CH3-Orexin A and 11C-raclopride uptake in rhesus macaque brain after intranasal administration. 11C-CH3-Orexin A (A) and 11C-raclopride (B) were administered using a device for intranasal delivery to the neuroepithelium. At 90 minutes, 11C-CH3-Orexin A was not visible in the brain using PET/MRI, while 11C-raclopride was readily visible in the basal ganglia.
