Tissue oxygenation can be characterized by local oxygen saturation (lSO2), which may be mapped by quantitative Blood Oxygen Level Dependent (BOLD) approaches. An approach that combines separate estimates of T2, T2*, BVf, and B0 inhomogeneities has recently been proposed and validated in rats and a preliminary study has been realized in humans. The aim of this study is to evaluate this approach in non human primates under two depth of anesthesia.
