Imaging is an important tool in the pediatric emergency department to guide diagnosis and treatment. In this study, researchers analyzed more than 3.6 million emergency department visits for patients younger than 18 years to evaluate racial and ethnic differences in diagnostic imaging rates. One-third of visits by non-Hispanic white children included imaging, compared with 24% of visits by non-Hispanic Black and 26% of Hispanic children. Given the risks of both radiation exposure and missed diagnoses, strategies to mitigate these disparities must be investigated.
