Japanese Diagnostic Reference Levels (DRLs) were released as "Japan DRLs 2015" from Japan Network for Research and Information on Medical Exposure (J-RIME) in June 2015. In "Japan DRLs 2015", DRLs in angiography and interventional procedures are set at a fluoroscopic dose rate of 20 mGy/min at the interventional reference point using a phantom. In order to achieve optimization with DRLs, then it need to be revised regularly. Therefore, we (research group to examine the effect of Japan DRLs 2015 and the necessity of additional items in angiography and vascular interventions) examined the effects of "Japan DRLs 2015" on angiography and interventional procedures. And we also investigated for DRLs revision in the future. As a result, it turned out that it is important to create DRLs in medical procedures that can be effectively used in clinical settings.
日本诊断参考水平（DRLs）于2015年6月由日本医学照射研究与信息网络（J-RIME）以“2015年日本DRLs”的形式发布。在“2015年日本DRLs”中，血管造影和介入程序中的DRLs是在使用体模的介入参考点处将荧光透视剂量率设定为20 mGy/分钟。为了通过DRLs实现优化，需要定期对其进行修订。因此，我们（研究小组，旨在研究2015年日本DRLs的效果以及血管造影和血管介入中新增项目的必要性）研究了“2015年日本DRLs”对血管造影和介入程序的影响。并且我们还对未来DRLs的修订进行了调查。结果表明，在医疗程序中创建能够在临床环境中有效使用的DRLs非常重要。
