Fig. 4.
PET SUV images of [11C]AFM summed from 30 to 60 min post-injection in (a) the baseline scan and (b) citalopram blocking scan of a healthy human subject, as well as (c and d) two different SCI subjects. An obvious blockade of [11C]AFM uptake is seen in the brain and lungs of the healthy subject. The SUV color scale ranges from 0 to 3 % ID/g.
