In a double-blind randomised study 3 different concentrations of iohexol for bowel opacification at CT of the abdomen were compared. Iohexol in a concentration of 4.5 mg I/ml, 6.75 mg I/ml and 9 mg I/ml was used. No significant differences between the 3 preparations of contrast media were found regarding the contrast effect, the distribution or patient tolerance. When using iohexol as a bowel contrast medium at CT the concentration of 4.5 mg I/ml is sufficient for bowel opacification.
在一项双盲随机研究中，比较了腹部CT检查时用于肠道造影的3种不同浓度的碘海醇。使用的碘海醇浓度分别为4.5mg I/ml、6.75mg I/ml和9mg I/ml。在造影效果、分布或患者耐受性方面，未发现这3种造影剂制剂之间存在显著差异。在CT检查中使用碘海醇作为肠道造影剂时，4.5mg I/ml的浓度足以使肠道显影。
