A T2-based oximetry method for quantifying whole-organ metabolic rate of oxygen (MRO2): A velocity-encoded acquisition module with golden-angle radial sampling was inserted into a background-suppressed T2-prepared sequence specifically for blood water T2 quantification. Parallel imaging and compressed-sensing techniques were applied to the reconstruction of the sparsely-sampled velocity-encoded k-space data to generate velocity maps. Whole-organ oxygen metabolic rate was estimated by converting T2 to blood oxygenation level via a calibration curve. A pilot study in the superior sagittal sinus showed the method’s ability to estimate whole-brain CMRO2 (136±23 μmol/minute/100g, mean±S.D.) in a single pass.
