Abstract
The present specification discloses a method for measuring brain tissue oxygenation in a subject. The method comprises the following steps: measuring a magnetic signal in a reference voxel of the subject's brain while imposing a series of arterial oxygen saturation changes using sequential gas delivery; calculating a relationship between the magnetic signal and the arterial oxygen saturation in the reference voxel; measuring a magnetic signal in a target voxel; and calculating the hemoglobin saturation in the target voxel based on the established relationship between the magnetic signal and the SaO2 in the reference voxel. This calibration of magnetic signal for SaOenables the conversion of magnetic signal to SaOthroughout blood-containing voxels throughout the brain.
