A new method was introduced to measure arterial and microvascular cerebral blood volume (CBV) by combining multiphase trueFISP readout with arterial spin labeling. Both simulation and experimental results demonstrated well preserved longitudinal magnetization of flowing spins, which can be treated as an intravascular contrast agent for CBV measurement. The measured arterial and microvascular cerebral blood volume (CBV) was around 1.5%.
