Radiotherapy might have an influence on the ratio of deoxygenated versus oxygenated blood in the venous blood vessels (OEF) in the brain. The relationship between delivered dose and the OEF may be a more direct measure of tissue damage or recovery. Preliminary results suggest that there is a marginal significant increase in OEF values after radiotherapy. This indicates that OEF can be of valuable use in determining the effects of radiotherapy. Additionally, CMRO2 maps show an identical increase or decrease in cerebral metabolic activity.
