Figure 9: An 86-year-old woman presented with a large right temporal lobar hematoma, which is seen on the axial CT scan (arrows in A). On the raw data of time-resolved CT angiography (B-D), an increasing "spot sign" is seen (arrows) over the multiple volumes acquired during the late venous phase. This sign may be predictive of an increase in the hematoma volume over time, seen on the subsequent CT of the head (E) done 6 h later. The whole brain CTP (F-H) obtained from the CTA data shows evidence of perilesional ischemia with low CBF (arrows in F), low CBV (arrows in G), and high MTT (arrows in H
