Accurate measurement of cerebral metabolic rate of oxygen (CMRO2) is highly desired for the assessment of brain cell function in health and in stroke.MRI offers the potential to map CMRO2 by estimating paragmagnetic deoxyhemoglobin concentration ([dHb]) from detected signal, which requires MRI signal modeling. We propose to use a rigorous deconvolution technique called quantitative susceptibility mapping (QSM) to map [dHb] and hence CMRO2.
