Patient shielding is standard practice in diagnostic imaging, despite growing evidence that it provides negligible or no benefit and carries a substantial risk of increasing patient dose and compromising the diagnostic efficacy of an image. The historical rationale for patient shielding is described, and the folly of its continued use is discussed.
Although change is difficult, it is incumbent on radiologic technologists, medical physicists, and radiologists to abandon the practice of patient shielding in radiology.
尽管越来越多的证据表明患者屏蔽在诊断成像中提供的益处可以忽略不计或没有益处,但它仍存在显著增加患者剂量和影响图像诊断效果的风险,因此它是诊断成像中的标准做法。本文描述了患者屏蔽的历史原理,并讨论了继续使用它的愚蠢之处。
尽管改变是困难的,但放射技师、医学物理学家和放射科医生有责任放弃放射科中的患者屏蔽做法。
