The stimulus to create this document was the recognition that ionizing radiation-guided cardiovascular procedures are being performed with increasing frequency, leading to greater patient radiation exposure and, potentially, to greater exposure to clinical personnel. While the clinical benefit of these procedures is substantial, there is concern about the implications of medical radiation exposure. ACC leadership concluded that it is important to provide practitioners with an educational resource that assembles and interprets the current radiation knowledge base relevant to cardiovascular procedures. By applying this knowledge base, cardiovascular practitioners will be able to select procedures optimally, and minimize radiation exposure to patients and to clinical personnel. "Optimal Use of Ionizing Radiation in Cardiovascular Imaging - Best Practices for Safety and Effectiveness" is a comprehensive overview of ionizing radiation use in cardiovascular procedures and is published online. To provide the most value to our members, we divided the print version of this document into 2 focused parts. "Part I: Radiation Physics and Radiation Biology" addresses radiation physics, dosimetry and detrimental biologic effects. "Part II: Radiologic Equipment Operation, Dose-Sparing Methodologies, Patient and Medical Personnel Protection" covers the basics of operation and radiation delivery for the 3 cardiovascular imaging modalities (x-ray fluoroscopy, x-ray computed tomography, and nuclear scintigraphy). For each modality, it includes the determinants of radiation exposure and techniques to minimize exposure to both patients and to medical personnel.

:创建此文件的刺激因素是认识到电离辐射引导的心血管手术正在以越来越高的频率进行,从而导致更多的患者辐射暴露,并有可能增加对临床人员的暴露。尽管这些程序的临床益处是巨大的,但人们担心医学辐射的影响。 ACC的领导得出结论,为从业人员提供汇集和解释当前与心血管手术相关的辐射知识库的教育资源非常重要。通过应用该知识库,心血管医生将能够最佳地选择程序,并最大程度地减少对患者和临床人员的辐射暴露。 “在心血管成像中最佳使用电离辐射-安全性和有效性的最佳做法”是对心血管程序中电离辐射使用的全面概述,并在线发布。为了向我们的会员提供最大的价值,我们将本文档的印刷版分为2个重点部分。 “第一部分:辐射物理学和辐射生物学”阐述了辐射物理学,剂量学和有害生物效应。 “第二部分:放射设备操作,节省剂量的方法,患者和医务人员保护”涵盖了3种心血管成像模式(X射线荧光透视,X射线计算机断层扫描和核闪烁显像)的操作和放射线的基础知识。对于每种方式,它都包括辐射暴露的决定因素以及使对患者和医务人员的辐射最小化的技术。
