The purpose of this paper was to compare the clinical efficacy of iopamidol and iopromide, iohexol nonionic contrast media in terms of their image quality in Beagle dogs with hepatic CT angiography and their application in veterinary clinics. With 9 Beagle dogs, contrast media of iopamidol (pamiray-) and iopromide (ultravist-, iohexol (omnipaque-) were induced intravenously (600 mg I/kg, BW) and CT angiography was done under general anesthesia. CT scan included scout, pre-contrast and cine examinations. During CT angiography, peak HU (Hounsfield unit) and peak time were examined on each site (ROI; region of interest) of the aorta, caudal vena cava, potral vein and liver parenchyma. Any side effects were also examined. After experiments, it was found that there were no significant changes of HU and maximal enhancing time of each ROIs of aorta, caudal vena cava, portal vein and liver parenchyma between these contrast media. And any side effects were not noted. So it is concluded that iopamidol has similiar contrast enhancement like as iopromide and iohexol in hepatic angiography and and it is thought to be useful for evaluation of the abdominal organs by CT scan in veterinary clinics.
