Abstract：
To explore the data and supporting evidence for the 2019 statement by the American Association of Physicists in Medicine (AAPM) that recommends limits to the routine use of fetal and gonadal shielding in medical imaging.
Three researchers searched 5 online databases, selecting articles from scholarly journals and radiology trade publications. Search results were filtered to include literature published from January 1, 2016, to August 9, 2022, to ensure relevance and provide historical background for the 2019 AAPM statement.
The use of patient shielding during medical imaging did not reduce dose, and in certain instances, increased dose received by patients during computed tomography, fluoroscopy, or dental imaging. The use of shielding interfered with technology designed to reduce patient dose, including automatic exposure control and dose modulation. Research showed that errors in shield placement were common and that shields can act as sources of infection or carriers of harmful lead dust.
In each article reviewed, a compelling case was made for discontinuing routine patient shielding during radiographic procedures. Serious opposition to the discontinuation of the shielding practice was not found. Opportunities exist for further study into technologists\' and the public\'s understanding of the effects of radiation and technologists\' compliance with new shielding policies.
The challenges with properly using shielding, paired with recent technological advancements and a new understanding of radiation protection, have negated the need for contact shielding. This legacy practice can be discontinued in clinical settings, and educational materials for technologists and students should be updated to reflect these changes.

摘要：
目的：探索美国医学物理学家协会（AAPM）2019年声明的数据和支持证据，该声明建议限制在医学成像中常规使用胎儿和性腺屏蔽。
方法：三名研究人员搜索了5个在线数据库，从学术期刊和放射学贸易出版物中选择文章。搜索结果经过过滤，包括2016年1月1日至2022年8月9日发布的文献，以确保相关性并为2019年AAPM声明提供历史背景。
结果：在医学成像期间使用患者屏蔽并没有减少剂量，在某些情况下,患者在计算机断层扫描期间接受的剂量增加，透视,或牙科成像。屏蔽的使用干扰了旨在减少患者剂量的技术，包括自动曝光控制和剂量调制。研究表明，防护罩放置错误很常见，防护罩可能会成为有害铅尘的感染源或携带者。
结论：在所审查的每篇文章中，在射线照相过程中，有令人信服的理由停止常规患者屏蔽。没有发现对终止屏蔽做法的严重反对。存在进一步研究技术人员和公众对辐射和技术人员遵守新屏蔽政策的影响的理解的机会。
结论：正确使用屏蔽的挑战，结合最近的技术进步和对辐射防护的新认识，已经否定了接触屏蔽的需要。这种传统做法可以在临床环境中停止，技术人员和学生的教育材料应该更新，以反映这些变化。
