Observed effects between the experimental SAH and sham group SAH animals showed a highly significant increased uptake ratio of [ 18 F]FDG (p ≤ 0.001) in gray matter compared to sham operated controls starting 3 h following SAH/sham operation and lasting significantly elevated (p ≤ 0.01) up to day 7 following SAH/sham operation.
