## BACKGROUND. Stereotactic radiotherapy (SRT) is fractionated radiotherapy delivered under stereotactic guidance to produce highly focal and precise therapy. We studied the incidence of imaging changes that can mimic tumor progression after completion of SRT for childhood low grade astrocytoma. #
Near-infrared spectroscopy was used to monitor the sequential changes in the cerebral oxygenation state during and after hyperventilation in two children with moyamoya disease. Hyperventilation induced the build-up phenomenon and a decrease in the concentration of oxy-hemoglobin ([oxy-Hb]) and total
