<unk>  is a method of computed tomography <unk><unk>  used for neuroimaging in which the subject inhales xenon gas while<unk>  images are made. 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. The diffusion of the gas into the tissues shows how much blood flow each area is getting.
