Fig. 5From: Effects of common anesthetic agents on [18F]flumazenil binding to the GABAA receptor a Radioactivity concentrations in dissected brain regions and blood samples at 60Â min post [18F]flumazenil injection, values are given as the %ID/g in the region of interest. b Comparison of the radioactivity concentrations in sampled whole blood (ex vivo) vs. the image-derived heart concentration from the PET scanner. Significant differences are reported relative to the awake conditionBack to article page
