Iodinated contrast agents in neuroradiology
Neuroimaging Clinics of North America, 1994Intravascular iodinated contrast materials in neuroradiology commonly are used during CT scanning and cerebral arteriography. This article discusses their use and the selection of appropriate contrast media. Adverse contrast media reactions, with emphasis on neurotoxicity, and the use of low osmolar agents are discussed.

Iodinated contrast agents as “radiosensitisers”
The British Journal of Radiology, 1987The sole purpose of radio-contrast agents is to increase the absorption of X rays in blood vessels and soft tissues. Current diagnostic agents take advantage of the properties of iodine with its acceptably low clinical toxicity and moderately high atomic number (53), the latter yielding a relatively large absorption coefficient for photons in the ...

Iodinated contrast sensitivity in ERCP
The American Journal of Gastroenterology, 2000Iodine contrast media are detectable in the bloodstream after ERCP, and sensitivity reactions have been described. The risk is very small, and the phenomenon is therefore difficult to study. This review discusses the possible need for preventative strategies, and recommends that endoscopists consider the issue and define their own policies.

In neuroimaging, iodine-based contrast agents are administered intravenously when acquiring CT images mainly for evaluating infectious and inflammatory conditions and tumors. Intravenous administration of iodine-based contrast agents are also an essential part of CT and conventional catheter angiography and CT perfusion studies.

Current Radiographic Iodinated Contrast Agents
Magnetic Resonance Imaging Clinics of North America, 2017Millions of radiologic examinations requiring the use of iodinated contrast are performed yearly in North America. Triiodobenzoic acid, the contrast agent molecule currently in use, is a benzene ring covalently bonded to the 3 iodine atoms. Iodinated contrast media can be divided in 4 categories: ionic monomers, ionic dimers, nonionic monomer, and ...

Reactions to Iodinated Contrast Media
Pediatrics In Review, 1996The exact mechanism responsible for adverse reactions to iodinated contrast administered intravenously during radiologic evaluation is not known. However, through work that has been performed both in the laboratory and in clinical trials, we do know that the types of reactions are variable and the underlying etiologies multifactorial.

Angiographic Nephrectomy Using Iodinated Contrast Agent
Investigative Radiology, 1981Diatrizoate meglumine and sodium (Renografin-76) was perfused in an obstructed renal artery in 13 dogs. Intense and prolonged accumulation of contrast agent ("contrast staining") was achieved in all animals. Repeat injection was frequently necessary to enhance staining. Renin output from the stained kidneys was lower than that from the opposite kidneys.

Nephroprotection and iodinate contrast medias
Radiología (English Edition)The incidence of post-contrast acute kidney injury (PC-AKI) is low with the new low- or iso-osmolar non-ionic iodinated contrast agents. The only proven form of prophylaxis for PC-AKI is hydration, preferably intravenous, although oral hydration is equally effective.
