Abstract:
Intravenous contrast media are used in MRI, CT and US studies for anatomical evaluation and lesion characterization. Safety is always of paramount importance when administering any contrast media to children, and it is important for radiologists and ordering providers to be knowledgeable of the safety profiles and potential adverse events that can occur. This manuscript reviews the frequency and types of adverse events associated with intravenous contrast agents reported in the pediatric literature. Overall, intravenous contrast agents are very safe to use in children. However, familiarity with how to treat and prevent these uncommon events is crucial in preventing poor outcomes. In addition, an understanding of gadolinium deposition in tissues can help facilitate conversations with concerned physicians and parents. This review provides a concise yet comprehensive reference for radiologists and ordering providers on intravenous contrast safety considerations in the pediatric patient.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
