Fraction of Inspired Oxygen in Relation to Cerebrospinal Fluid Hyperintensity on FLAIR MR Imaging of the Brain in Children and Young Adults Undergoing Anesthesia

Abstract

High inspired oxygen fraction during anesthesia is associated with CSF hyperintensity in the basilar cisterns and the cerebral sulcal subarachnoid space on FLAIR imaging in children and young adults. Physicians should be aware of this finding to avoid misinterpreting this artifact as an abnormality.
