Abstract
Adverse reactions to intravenous iodinated contrast media may be classified as general and organspecific such as contrastinduced nephrotoxicity General adverse reactions may be subclassified into acute and delayed types Acute general adverse reactions can range from transient minor reactions to lifethreatening severe reactions Nonionic contrast media have lower risk of mild and moderate adverse reactions However the risk of fatal reactions is similar for ionic and nonionic contrast media Adequate preprocedure evaluation should be performed to identify predisposing risk factors Prompt recognition and treatment of acute adverse reactions is crucial Risk of contrast induced nephrotoxicity can be reduced by use of nonionic contrast media less volume of contrast and adequate hydration The radiologist can play a pivotal role by being aware of predisposing factors clinical presentation and management of adverse reactions to contrast media
