Weight-adapted iodinated contrast media administration in abdomino-pelvic CT: Can image quality be maintained?

Highlights: • Weight-adapted contrast regimes have the potential to reduce contrast dose in abdominopelvic CT. • Patients weighing 76 kg or below received a lower contrast dose using a weight-adapted protocol. • There are potential cost savings through implementing a weight-adapted protocol. - Abstract: IntroductionIn many centres, a fixed method of contrast-media administration is used for CT regardless of patient body habitus. The aim of this trial was to assess contrast enhancement of the aorta, portal vein, liver and spleen during abdomino-pelvic CT imaging using a weight-adapted contrast media protocol compared to the current fixed dose method.
