title: Acute renal failure after enhanced computed tomography.
abstract: Acute renal failure has been reported after the administration of a variety of radiographic contrast media. We treated a patient with preexisting renal insufficiency who received contrast media during computed tomography (CT) and had acute renal failure. The fractional excretion of sodium (FENa) was observed to be 0.2% before contrast media exposure and 3.5% after exposure. Patients with risk factors leading to contrast media-induced acute renal failure should be carefully screened before receiving enhanced CT.
