Abstract:
:Renal failure induced by intravenous iodinated contrast media is a frequent medical problem. While such cases are generally reported first by the clinician, the phenomenon can be seen even earlier by the radiologist. An abnormally persistent nephrogram is a sign of abnormal clearance, which in turn should alert the physician to the likelihood of renal failure.
