Figure 2: Four perfusion mapping techniques of CTP, including CBF (a), CBV (b), TTP (c), and MTT (d) are shown. The color scale bar of CBF and CBV (e), and TTP and MTT (f), with 50% and 75% cut points. CTP – Computed tomography perfusion; CTA – Computed tomography angiography; TTP – Time to peak; CBF – Cerebral blood flow; MTT – Mean transit time
