CT perfusion axial view at the level of the sylvian fissure demonstrate reduced TTP (white arrows) in the parietal-temporal lobe with corresponding increase in cerebral blood flow (CBF) (white arrows) and cerebral blood volume (CBV) (white arrows) suggestive of increased blood flow in these areas. There was no much observable change in the MTT. Mean transit time (MTT), is a measure of the mean time for blood/contrast to perfuse a region of tissue. Cerebral blood volume (CBF) = CBV/MTT.

The brain CT perfusion (CTP) showed [Figures 1 and 2] reduced time to peak (TTP), increased cerebral blood flow (CBF), and volume (CBV).
