Abstract Objective: To compare the application of iohexol of different concentrations in arterial phase display with enhanced abdominal CT.Methods: 289 patients with suspected abdominal lesions from March 2016 to February 2019 in the First People's Hospital of Xining City were retrospectively selected.According to the mass concentration of iohexol, they were divided into two groups: low concentration group (300mg/mL, n=145) and high concentration group (350 mg/mL, n = 144).The scanning time, image quality and adverse events of the two groups were statistically analyzed.Results: The differences of trigger time of arterial phase and actual scanning time between the two groups were not statistically significant (P>0.05), nor in the CT value of abdominal aorta (P>0.05).The differences of noise and signal-to-noise ratios of abdominal aorta in arterial phase between the two groups were not statistically significant (P>0.05).The incidence of adverse events was 1.4% (2/145) in the low concentration group and 5.6% (8/144) in the high concentration group.The former was significantly lower than the latter, and the difference was statistically significant (P<0.05).Conclusion: The application effect of iohexol of low concentration in arterial phase display with enhanced abdominal CT is safer than iohexol of high concentration, so it is worthy of promotion.
