提出介入放射学的国家诊断参考水平（DRL），并评估程序复杂性对患者剂量的影响。来自西班牙医院的八个介入放射科单位参与了该项目。参与者同意接受 X 射线系统的通用质量控制程序。比释动面积积 (KAP) 是从 1,649 个程序的样本中收集的。一份共识文件制定了评估七种程序复杂性的标准。 DRL 被设置为 KAP 值的第三个四分位数。调查中包含的程序的 KAP（第三个四分位数）以 Gy cm(2) 为单位： 下肢动脉造影 (n = 784) 78；肾动脉造影 (n = 37) 107;经颈静脉肝活检 (THB) (n = 30) 45;胆汁引流 (BD) (n = 314) 30;子宫肌瘤栓塞术 (UFE) (n = 56) 214;结肠内置假体 (CE) (n = 31) 169;肝化疗栓塞 (HC) (n = 269) 303;股腘血管重建术 (FR) (n = 62) 119;和髂支架 (n = 66) 170. 复杂性涉及以下 KAP 因素从简单到复杂程序的增加： THB x4； BD x13； UFE x3； CE x3； HC x5； FR x5 和 IS x4。对患者剂量中的程序复杂性进行评估将允许正确使用 DRL 来优化介入放射学。a 欧元 已建议给定复杂程度的介入程序的国家 DRL。a 欧元 对于临床审核，应考虑复杂性水平。a 欧元 应对程序的复杂性水平进行评估。
To propose national diagnostic reference levels (DRLs) for interventional radiology and to evaluate the impact of the procedural complexity on patient doses.Eight interventional radiology units from Spanish hospitals were involved in this project. The participants agreed to undergo common quality control procedures for X-ray systems. Kerma area product (KAP) was collected from a sample of 1,649 procedures. A consensus document established the criteria to evaluate the complexity of seven types of procedures. DRLs were set as the 3rd quartile of KAP values.The KAP (3rd quartile) in Gy cm(2) for the procedures included in the survey were: lower extremity arteriography (n = 784) 78; renal arteriography (n = 37) 107; transjugular hepatic biopsies (THB) (n = 30) 45; biliary drainage (BD) (n = 314) 30; uterine fibroid embolization (UFE) (n = 56) 214; colon endoprostheses (CE) (n = 31) 169; hepatic chemoembolization (HC) (n = 269) 303; femoropopliteal revascularization (FR) (n = 62) 119; and iliac stent (n = 66) 170. The complexity involved the increases in the following KAP factors from simple to complex procedures: THB x4; BD x13; UFE x3; CE x3; HC x5; FR x5 and IS x4.The evaluation of the procedure complexity in patient doses will allow the proper use of DRLs for the optimization of interventional radiology.aEuro cent National DRLs for interventional procedures have been proposed given level of complexityaEuro cent For clinical audits, the level of complexity should be taken into account.aEuro cent An evaluation of the complexity levels of the procedure should be made.
