Background Acute kidney injury (AKI) remains a concern in hospitalized children undergoing CT with intravenous iodinated contrast material (ICM). Adult studies have shown frequencies of AKI after CT with intravenous ICM to be similar to propensity score-matched ICM-unexposed patient groups; similar data in pediatric patients are lacking. Purpose To evaluate the association between intravenous ICM exposure and AKI in hospitalized pediatric patients with stable kidney function undergoing contrast material-enhanced CT by comparing with a propensity score-matched ICM-unexposed patient sample undergoing abdominal US. ⋯ Conclusion Hospitalized children with stable kidney function who underwent CT with intravenous iodinated contrast material (ICM) had a similar frequency of acute kidney injury (AKI) compared with a propensity score-matched ICM-unexposed patient group. In pediatric inpatients with estimated glomerular filtration rate greater than or equal to 60 mL/min/1.73 m2, ICM was not independently associated with AKI. © RSNA, 2020 Online supplemental material is available for this article.
