Large exposures incurred in interventional radiology procedures make it advisable to establish reference dose values. These dose values should be quoted in quantities representative of the radiological risk to the patient. In Spain, measurement methods were developed to comply with the European Directive on Patient Protection. Dose-area product and, when feasible, surface dose using thermoluminescent dosimetry chips were measured. Both approaches are discussed, as well as their potential use in patient protection programmes. Initial results are presented for a sample of 680 patients in 10 hospital centres in Spain. Mean, median and range are reported for some specific procedures. Mean values of 8750, 6651, 6663, 9292 and 6816 cGy cm2 are reported for percutaneous transluminal coronary angioplasty, coronary angiography, low extremity, renal and cerebral arteriographies, respectively.
介入放射学程序中涉及的大量辐射暴露使得建立参考剂量值成为必要。这些剂量值应以代表患者放射风险的量来引用。在西班牙，为遵守欧洲患者保护指令开发了测量方法。测量了剂量面积乘积，并在可行时使用热释光剂量测定芯片测量表面剂量。讨论了这两种方法及其在患者保护计划中的潜在用途。给出了西班牙10个医院中心680名患者样本的初步结果。报告了一些特定程序的均值、中位数和范围。经皮腔内冠状动脉成形术、冠状动脉造影、下肢动脉造影、肾动脉造影和脑血管造影的均值分别报告为8750、6651、6663、9292和6816 cGy cm²。
