Fig. 1From: PET quantification of brain O-GlcNAcase with [18F]LSN3316612 in healthy human volunteersT1-weighted magnetic resonance (MR) and [18F]LSN3316612 positron emission tomography (PET) images of a healthy volunteer. Although the brain had high uptake of radioactivity, the skull had virtually none. The concentration of radioactivity in the brain is expressed as standardized uptake values (SUV), which was measured from 120 to 180 minBack to article page
