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.[1] The method can be used to assess changes in cerebral blood flow in the period shortly after a traumatic brain injury,[1] or to detect or indicate the location of a stroke.[2] 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.[1]
