McDonald JS, et al. - In this retrospective cohort study involving pediatric (aged <18 years) patients who had either contrast-enhanced (contrast group) or unenhanced (noncontrast group) computed tomography (CT), researchers determined the rates of postcontrast acute kidney injury (AKI), dialysis therapy, and death after administration of intravenous contrast material. They reported very low rates of postcontrast AKI, dialysis therapy, and death following contrast-enhanced CT in this pediatric cohort. Although not detectably different, an effect of contrast on these outcomes could not be ruled out.
