Although diagnostic and interventional fluoroscopic procedures are amongst the highest dose examinations performed in radiology, these procedures currently lack established national diagnostic reference levels (DRLs) in Australia. In this absence, local diagnostic reference levels (LDRLs) are proposed for a wide range of diagnostic and interventional angiographic and fluoroscopic procedures based upon data collected from 11,000 examinations, performed over a 2.5 year period at a major Australian public, teaching hospital. Each procedure type assessed included a minimum of 50 cases. LDRLs were defined for each procedure in terms of the 75th percentile of the dose area product and median fluoroscopic times have also been provided. The detailed categories of procedures used in this study may inform the Australian Radiation Protection and Nuclear Safety Agency when establishing national DRLs for angiographic and fluoroscopic procedures. Until national DRLs for these complex procedures are available, these LDRLs may provide guidance to other institutions on achievable dose levels.
尽管诊断性和介入性荧光透视检查是放射学中剂量最高的检查项目之一，但目前在澳大利亚，这些检查尚无既定的国家诊断参考水平（DRL）。在此情况下，基于在澳大利亚一家大型公立教学医院2.5年期间收集的11000例检查数据，针对广泛的诊断性和介入性血管造影及荧光透视检查项目提出了当地诊断参考水平（LDRL）。评估的每种检查类型至少包含50个病例。根据剂量面积乘积的第75百分位数为每种检查定义了LDRL，同时还提供了荧光透视时间中位数。本研究中使用的详细检查类别可为澳大利亚辐射防护与核安全局制定血管造影和荧光透视检查的国家DRL提供参考。在这些复杂检查的国家DRL出台之前，这些LDRL可为其他机构提供可实现剂量水平方面的指导。
