Perfluoro carbon bromides as contrast media in radiography of the central nervous system. A preliminary experimental report.
A preliminary investigation of the properties of perfluorooctyl bromide in the subarachnoid space revealed this compound to have suitable attenuation capacity and advantageous physical and biologic properties for demonstration of the brain and spinal cord. No acute or chronic neurotoxicity was encountered. Microscopy demonstrated evidence of chronic inflammatory changes subsequent to long term exposure to the compound. It was concluded that the medium was superior to iodophendylate in several respects and that it may provide an alternative to water-soluble contrast media. Perfluorohexyl bromide proved unsuitable for neuroradiologic use because of formation of excessive amounts of non-absorbable gas, leading to high subarachnoid pressure and severe neurologic deficits.
