Transient reduction in renal function following arteriography: a radionuclide study.

The effects of iodinated contrast agents upon renal function were determined in 11 patients undergoing arteriography. Serial radionuclide renograms were performed to calculate the glomerular filtration rate, effective renal plasma flow and filtration fraction before and after arteriography. The effective renal plasma flow was the parameter most adversely affected. The magnitude of renal dysfunction depended upon the amount of contrast medium administered, as well as probably pre-existing renal disease and site of injection.
