The aim of this study was to compare radiology statistics and procedures across the world with an eye to lightening the workload of radiologists in Japan.
Literature and data in the public domain were obtained for Organization for Economic Cooperation and Development (OECD) member countries. This study collected and analyzed the number of (diagnostic) radiologists and physicians, computed tomography/magnetic resonance (CT/MR) units, CT/MR examinations, and workload of radiologists.
Data for the number of radiologists and CT/MR units were obtained from 26 countries and, among them, data for the number of CT/MR examinations for 17 countries. The study found that in 2004 Japan had only 36 radiologists per million population, which is one-third the national average of the 26 countries surveyed, making Japan one of the lowest ranked countries. The workload of a radiologist (CT/MR examinations/year) in Japan was calculated at 6130. This is 4.3 times the global average (1440 for the 17 countries).
This comparison showed that the number of radiologists in Japan is the lowest among the 26 countries, and the workload is the highest. The study also showed that for Japan to provide sustainable and quality health care 8614 diagnostic radiologists--2.5 times the present number- -would be required.
本研究旨在比较全球范围内的放射学统计数据和程序，以期减轻日本放射科医生的工作量。
获取经济合作与发展组织（OECD）成员国公共领域的文献和数据。本研究收集并分析了（诊断）放射科医生和内科医生的数量、计算机断层扫描/磁共振成像（CT/MR）设备数量、CT/MR检查数量以及放射科医生的工作量。
从26个国家获取了放射科医生数量和CT/MR设备数量的数据，其中17个国家提供了CT/MR检查数量的数据。研究发现，2004年日本每百万人口中仅有36名放射科医生，这是所调查的26个国家平均水平的三分之一，使日本成为排名最低的国家之一。日本放射科医生的工作量（每年CT/MR检查次数）经计算为6130次。这是全球平均水平（17个国家为1440次）的4.3倍。
该比较表明，日本放射科医生数量在26个国家中是最少的，而工作量是最高的。研究还表明，日本若要提供可持续且高质量的医疗服务，将需要8614名诊断放射科医生——是目前数量的2.5倍。
