One of the adverse events associated with administration of intravenous (IV) contrast media is contrast-induced nephropathy, yet its incidence is poorly characterized. We investigated the incidence of contrast-induced nephropathy in patients with elevated baseline serum creatinine concentrations who underwent computed tomography (CT) using IV contrast media. ⋯ The role of IV contrast media in causing contrast-induced nephropathy and, thus, acute kidney injury, may be overestimated. Further study needs to be done into whether contrast-induced nephropathy is truly a common or even a real entity in patients receiving IV contrast media for routine studies who have no other risk factors for kidney injury warranting the expense, risks, and inconvenience of pretreatment.
