To date CIN has received minimal attention in the veterinary literature despite increasing use of contrast medium examinations in computed tomographic studies. METHODS This prospective study evaluated the effect of 1290 mg/kg iohexol given intravenously to 5 normal beagle dogs in a divided dose at an interval of 6–8 weeks. Renal function was evaluated by means of scintigraphically determined glomerular filtration rate (GFR) and a variety of laboratory assays. RESULTS Only GFR showed a significant decrease (17%) after the second injection but not to a clinically or pathologically significant level. CONCLUSIONS No clinically significant effect of repeated contrast medium administration was determined in this limited study. However in dogs with reduced renal function the risk of CIN is likely to increase dramatically post contrast administration.en© 2012 Kirberger et al. ; licensee BioMed Central Ltd.
