Comparison of side effects during cerebral computed tomography with a nonionic (iohexol) and an ionic (metrizoate) contrast medium.
نویسندگان
چکیده
Cerebral computed tomography was performed in 60 patients referred for pre- and postcontrast scanning. The patients were randomly sampled with a nonionic contrast medium, iohexol, and an ionic contrast medium, sodium metrizoate. No complications were seen, and the adverse effects, usually a feeling of warmth, were very minor with both contrast media, but iohexol caused less discomfort than sodium metrizoate. A series of measurements of the attenuation values of well defined intracranial structures was performed and no difference in enhancement was found between the two contrast media.

High performance liquid chromatography with multiwavelength detection: a technique for identification of iodinated x-ray contrast agents in human body fluids and brain tissue.
PURPOSE Several cases of a severe adverse reaction, referred to as "ascending tonic-clonic seizure syndrome," have been reported after administration of water-soluble iodinated x-ray contrast agents for myelographic examinations. Because of the bizarre reactions, the identities of the causative contrast media were questioned. METHODS Analyses of biologic materials from four of these patients ...

متن کاملA comparison of iopamidol and iohexol in cerebral angiography.
Iopamidol and iohexol, the new nonionic low-osmolality contrast agents, have both been shown to be safe, effective, and better tolerated than conventional ionic agents for cerebral angiography. In this randomized, double-blind study involving 40 patients, these two agents were compared for adverse effects, radiographic quality, and patient tolerance. No significant differences were observed in ...
متن کاملAdministration and dosage of iohexol, a nonionic contrast medium, for dynamic renal computed tomography.
We investigated the optimal method of administering iohexol, which contains 300 mg iodine/ml (Omnipaque 300), a nonionic contrast medium, to maintain adequate renal contrast while reducing artifacts during dynamic CT scanning. In this study, 76 patients with renal disease received 10-50 ml of iohexol as follows: group I (14 patients), 20 ml injected as an intravenous bolus for 5 sec, followed b...

Facial muscle twitching during intracarotid injections of nonionic contrast media has been observed in rabbits. To investigate the cause of this reaction, cortical EEG and facial EMG recordings were made from rabbits receiving selective internal and external carotid artery injections of control solutions (normal saline, mannitol), an ionic contrast medium (meglumine iothalamate), and three noni...
