Abstract

We carried out a nationwide questionnaire survey of pediatric computed tomography (CT) in 339 facilities. Most facilities operated multi detector-row CT (MDCT), and over half operated 64, 128, 256 and 320-slice MDCT. In 32% of facilities, pediatric CT protocols were set taking image quality and dose into consideration. However, in the other facilities, pediatric CT protocols may not be optimized because there is no clear standard for image quality or dosage for pediatric CT examinations in Japan. To promote the optimization of pediatric CT protocols, we regard it as an urgent task to establish diagnostic reference levels for pediatric CT examinations.

摘要

我们对339家机构的儿科计算机断层扫描（CT）进行了一项全国性问卷调查。大多数机构都配备了多排探测器CT（MDCT），超过半数的机构配备了64排、128排、256排和320排的MDCT。32%的机构在制定儿科CT检查方案时考虑了图像质量和辐射剂量。然而，在其他机构中，由于日本尚无明确的儿科CT检查图像质量或剂量标准，儿科CT检查方案可能未得到优化。为推动儿科CT检查方案的优化，我们认为建立儿科CT检查的诊断参考水平是一项紧迫任务。
