Zeiss Jacob; Brinker, RayJournal of Computer Assisted Tomography: March-April 1988 Case Report: PDF Only Buy Abstract Postcontrast cerebral CT offers advantages as an adjunct to noncontrast CT in the evaluation of patients with carbon monoxide intoxication. It is of particular value when the noncontrast CT is normal with its ability to enhance otherwise isodense lesions. In this regard it can more accurately define the extent of the CNS insult and in some instances offer insight into the patient's eventual clinical outcome. Contrast medium was useful in this instance to more clearly elucidate typical injury to globus pallidus as well as rather unusual involvement of putamen. © Lippincott-Raven Publishers.
