Abstract

We used ^17^O NMR imaging techniques to measure the H~2~^17^O concentration in a 0.8‐ml voxel in the cat brain following injection of an arterial bolus of enriched H~2~^17^O and during inhalation of enriched ^17^O~2~. We also measured the H~2~^17^O concentration in arterial blood during ^17^O~2~ inhalation. The data from the first measurement were used to calculate the blood flow in the voxel. The data from all three measurements were combined to calculate the oxygen consumption in the voxel. The values of cerebral blood flow and oxygen consumption calculated with ^17^O NMR techniques agree reasonably well with values calculated for a similar region of the cat brain using autoradiographic techniques.
