Knowledge
of blood T1 and T2 values are important for many MRI studies that include
BOLD modeling, high spatial specificity BOLD fMRI, blood flow MRI using
arterial spin labeling (ASL), and blood volume MRI using vascular space
occupancy (VASO) techniques. The purpose of the present study was to
determine blood T1 and T2 values at 11.7T as a function of oxygenation level
(Y), temperature, hematocrit fraction (Hct) and field strength (B0).
