Xenon-enhanced CT scanning is a method of computed tomography (CT scanning) used for neuroimaging in which the subject inhales xenon gas while CT images are made.{{cite journal |author=Zink BJ |title=Traumatic brain injury outcome: Concepts for emergency care |journal=Ann Emerg Med |volume=37 |issue=3 |pages=318–32 |date=March 2001 |pmid=11223769 |doi=10.1067/mem.2001.113505 }} The method can be used to assess changes in cerebral blood flow in the period shortly after a traumatic brain injury, or to detect or indicate the location of a stroke.{{cite book|last=Mallatt|first=Elaine N. Marieb, Patricia Brady Wilhelm, Jon|title=Human anatomy|publisher=Pearson|location=Boston|isbn=978-0321822413|page="Topics of Anatomy"|edition=Seventh edition.}} Xenon acts as a contrast medium and the saturation of brain tissue is proportional to blood flow. This allows the estimation of blood flow to any given brain area based on imaging results.
