Supplemental Oxygen Causes Increased Signal Intensity in Subarachnoid Cerebrospinal Fluid on Brain FLAIR MR Images Obtained in Children during General Anesthesia

Abstract

These findings are consistent with the hypothesis that increased arterial oxygen tension and consequently increased CSF Po(2) resulting from administration of high Fio(2) during general anesthesia are responsible for the increased CSF signal intensity noted on brain FLAIR MR images.
