Abstract

Two categories of single-photon radiopharmaceuticals for brain perfusion exist, nonlipophilic and lipophilic compounds. The former are useful in performing simple flow examinations which today have application primarily in the determination of brain death. The latter also exhibit a parenchymal uptake phase that allows for evaluation of the distribution of blood flow within the brain. The lipophilic radiopharmaceuticals, therefore, have application in the evaluation of patients following catastrophic brain injury and traumatic brain injury (TBI) and in prognosticating the outcome following cerebral vascular accidents. Use of these agents to monitor therapy with thrombolytic agents, although theoretically helpful, is technically difficult due to the need to institute treatment rapidly, without undue delay.
