Core Tip
Core tip: We hypothesized that intensive care unit (ICU) patients, especially pediatric patients, are potentially vulnerable to increased cumulative effective doses (CED) from ionizing radiation. We found a relatively low CED in the majority of ICU patients, during their stay in the ICU. Nevertheless, physicians are beholden to keep radiation exposures from diagnostic imaging as low as reasonably practical and CED should be minimized where feasible, especially in young patients. Physicians should be aware that trauma patients and patients with extended ICU admission times are at an increased risk of high CEDs.
