## Abstract __In vivo__ NMR experiments are performed to determine the degree of spin labeling for measurement of tissue perfusion by NMR using spin labeling of arterial water by adiabatic fast passage. Arterial water spins are labeled using flow in the presence of a field gradient and __B__~1~ irr

## Abstract To date, functional magnetic resonance imaging (fMRI) studies of the lateral geniculate nucleus (LGN) have primarily focused on measures of the blood oxygenation level dependent (BOLD) signal. Arterial spin labeling (ASL) is an MRI method that can provide direct measures of functional c
## Abstract A novel method for measuring the longitudinal relaxation time of arterial blood (__T__~1a~) is presented. Knowledge of __T__~1a~ is essential for accurately quantifying cerebral perfusion using arterial spin labeling (ASL) techniques. The method is based on the flowβsensitive alternatin
