A prospective double-blind randomised clinical trial of aortography and iliofemoral arteriography in 89 patients demonstrates that there is no difference in the diagnostic quality of the studies when Hexabrix 250 replaces Hexabrix 320. There is a minor reduction in patient subjective reaction, and the lower viscosity permits the use of smaller bore catheters. The major gain is that the cost of the contrast medium should be reduced by 22%.
一项针对89名患者的主动脉造影和髂股动脉造影的前瞻性双盲随机临床试验表明，当用Hexabrix 250替代Hexabrix 320时，研究的诊断质量没有差异。患者的主观反应略有降低，且较低的粘度允许使用更细内径的导管。主要的收获是造影剂成本应降低22%。
