An audit of Spanish private medicine radiodiagnostics facilities has been carried out, based partly on Spanish legislation relating to European Directives on health protection against ionizing radiation risks in medical exposure. The study included an appraisal of infrastructure and equipment, and aspects of quality assurance and radiation protection, by means of data collected through surveys. Of the 51 centres audited, a sample of 24 X-ray rooms was chosen, then an external evaluation with regard to image quality and patient dose was performed, by an advisory board of radiologists and medical physicists. The methodology used was similar to that of the group of European Union experts in European dose evaluation and image quality trials. Chest, abdomen, lumbar spine and breast examinations were monitored. Doses were measured with thermoluminescent dosimeters. A third of the X-ray rooms evaluated reached or exceeded dose reference values, and in a third of the cases the image quality left considerable room for improvement. Breast and chest examinations showed themselves to be the hardest to perform, not only as a result of exceeding the reference doses, but also due to failure to meet good image quality standards.
对西班牙私立医学放射诊断设施进行了一次审核，部分依据的是与欧洲关于医疗照射中电离辐射风险健康防护指令相关的西班牙立法。该研究通过调查收集的数据，对基础设施和设备以及质量保证和辐射防护方面进行了评估。在接受审核的51个中心中，选取了24间X光室作为样本，然后由放射科医生和医学物理学家顾问委员会对图像质量和患者剂量进行了外部评估。所采用的方法与欧盟专家小组在欧洲剂量评估和图像质量试验中使用的方法类似。对胸部、腹部、腰椎和乳房检查进行了监测。剂量用热释光剂量计测量。三分之一的被评估X光室达到或超过了剂量参考值，并且在三分之一的案例中，图像质量有很大的改进空间。乳房和胸部检查不仅由于超过参考剂量，而且由于未达到良好的图像质量标准，被证明是最难进行的检查。
