Steady-state arterial spin tagging approaches can provide quantitative images of CBF, but have not been validated in humans. The work presented here compared CBF values measured using steady-state arterial spin tagging with CBF values measured in the same group of human subjects using the H(2)(15)O
## Abstract A simple fourβcompartment model for magnetization transfer was used to obtain theoretical expressions for the relationship between regional cerebral blood flow and Ξ__M__, the change in longitudinal magnetization of brain water spins when arterial water spins are perturbed. The theoreti
