Diagnostic radiographs, computed tomography (CT), nuclear medicine studies, and intraoperative fluoroscopy durations were analyzed for radiation exposure. Cumulative and yearly effective ionizing radiation doses, cumulative background radiation, and total radiograph studies were compared between pediatric and adult populations. In 24 patients with 1,246 imaging studies (average 5.5 years longitudinal treatment duration), the mean estimated cumulative effective radiation dose per patient was 30.0 mSv (range 2.3-115.0), with an average yearly dose of 4.9 mSv (range 0.4-24.8). Pediatric patients had significantly more radiograph studies per year than adults and greater average yearly effective radiation doses.
对诊断性X光片、计算机断层扫描（CT）、核医学检查以及术中透视时间进行了辐射暴露分析。比较了儿童和成人人群的累积和年度有效电离辐射剂量、累积背景辐射以及X光片检查总数。24例患者接受了1246次成像检查（平均纵向治疗时间为5.5年），每位患者的平均估计累积有效辐射剂量为30.0毫希沃特（范围为2.3 - 115.0），平均每年剂量为4.9毫希沃特（范围为0.4 - 24.8）。儿童患者每年的X光片检查比成人显著更多，且平均每年有效辐射剂量更高。
