Transverse MR spin relaxation rates, R2*, R2 and R2’ have all been considered sensitive to brain tissue oxygenation. In this study, we focus on a cohort of pre-operative Moyamoya disease patients and simultaneously map all three rates in addition to cerebral blood flow, both before and after the injection of the vasodilatory drug, acetazolamide. We found our measurements to be consistent with physiology and previous studies, and to support the use of R2’ for oxygenation mapping instead of R2* and R2.
