确定以人群为基础的儿童电离辐射诊断成像程序使用率，按年龄和性别分层。回顾性队列分析。所有设置使用电离辐射成像程序。在2005年1月1日至2007年12月31日期间，在美国5个大型医疗保健市场连续注册的18岁以下的个人。儿童电离辐射诊断成像程序的数量和类型。确认了355,088名儿童。150,930例（42.5%）患者共进行了436,711次电离辐射成像手术。使用率最高的是10岁以上的儿童，两岁以下的婴儿也经常使用。x线平片占影像学检查的近85%。计算机断层扫描（CT）——与高剂量辐射相关——是常用的，占研究期间所有手术的12%。总体而言，7.9%的儿童接受了至少一次CT检查，3.5%的儿童接受了两次或更多CT检查，其中头部CT最常见。暴露于医学诊断成像程序产生的电离辐射可能经常发生在儿童中。应鼓励努力优化和确保在儿科人群中适当使用这些程序。
To determine population-based rates of use of diagnostic imaging procedures with ionizing radiation in children, stratified by age and gender. Retrospective cohort analysis. All settings utilizing imaging procedures with ionizing radiation. Individuals less than 18 years old, alive and continuously enrolled in Unitedhealthcare between January 1, 2005 and December 31, 2007 in 5 large U.S. healthcare markets. Number and type of diagnostic imaging procedures utilizing ionizing radiation in children. 355,088 children were identified. A total of 436,711 imaging procedures using ionizing radiation were performed in 150,930 (42.5%) patients. The highest rates of use were in children greater than 10 years old, with frequent use in infants under 2 years old as well. Plain radiography accounted for nearly 85% of imaging procedures performed. Computed tomography (CT) scans – associated with substantially higher doses of radiation – were commonly used, accounting for 12% of all procedures during the study period. Overall, 7.9% of children received at least one CT and 3.5% received 2 or more, with CT of the head most frequent. Exposure to ionizing radiation from medical diagnostic imaging procedures may occur frequently among children. Efforts to optimize and ensure appropriate use of these procedures in the pediatric population should be encouraged.
