Polymers for Improved Delivery of Iodinated Contrast Agents.

ACS Biomaterials Science & Engineering, 2021
X-ray computed tomography (CT), as one of the most widely used noninvasive imaging modalities, can provide three-dimensional anatomic details with high resolution, which plays a key role in disease diagnosis and treatment assessment.

Iodinated contrast agents as “radiosensitisers”

The British Journal of Radiology, 1987
The 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, 2000
Iodine 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.

Reactions to Iodinated Contrast Media

Pediatrics In Review, 1996
The 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.

Iodinated Contrast Agents

2015
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.

Nephrotoxicity of Iodinated Contrast Agents

2021
Post-contrast acute kidney injury (PC-AKI) is defined as acute renal impairment within 48 h following exposure to intravascular iodinated contrast agents (ICAs). Contrast-induced nephropathy (CIN) is an iatrogenic disorder caused by renal degeneration due to ICA exposure.

Hypersensitivity Reactions to Iodinated Contrast Media: A Multicenter Study of 196 081 Patients.

Radiology, 2019
Background Multicenter studies may be required for establishing guidelines for safe usage of iodinated contrast media (ICM). Purpose To identify the prevalence, patterns, risk factors, and preventive measures for ICM-related hypersensitivity reactions ...

Iodinated contrast agents in neuroradiology

Neuroimaging Clinics of North America, 1994
Intravascular 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.

Relationship between Lower Dose and Injection Speed of Iodinated Contrast Material for CT and Acute Hypersensitivity Reactions: An Observational Study.

Radiology, 2019
BackgroundThere are few data on the relationship between acute hypersensitivity reactions and the dose and injection rate of iodinated contrast material for CT.PurposeTo determine the relationship between lower dose and injection speed of iodinated ...

Current iodinated contrast media

European Radiology, 2001
The number of scientific papers on iodinated contrast media is declining. Indeed, comparative trials between high-osmolality and low-osmolality agents largely showed the higher safety and tolerability of the latter, and this is no longer a matter of discussion.
