Cerebral hypoxia can potentially impact treatment outcome and brain tumor patient survival. Preliminary results of a non-contrast MR procedure for measuring brain and brain tumoral OEF are presented and compared with the results obtain using the noninvasive 15O-PET technique. Although good correlation between OEF-MR and OEF-PET is obtained, and both method show abnormality in tumor area, some discrepancy between the two methods is observed which requires further investigation.
