To determine whether radiologic technologists are manipulating projections to lower patient dose in routine pediatric radiography examinations.
Using a descriptive survey approach, members from the American Society of Radiologic Technologists with a primary registration in radiography were randomly selected and invited to share their experiences using alternative projections during routine pediatric radiography examinations.
For this study, 404 completed responses were analyzed. More than half of the participants (67.6%) strongly agreed or somewhat agreed that the use of alternative projections can reduce pediatric dose during routine radiography examinations, and more than half (61.3%) strongly agreed, agreed, or somewhat agreed that the use of alternative projections is beneficial for dose reduction. Incidentally, the most common response from participants regarding their use of alternative projections during routine pediatric radiography examinations was occasionally or sometimes. Nearly three-fourths of the participants strongly agreed that radiation protection guidelines are important to follow during routine pediatric radiography examinations. Although many radiologic technologists in this sample felt proficient using alternative projections during pediatric procedures, they also believed additional training in such methods would be beneficial.
Most institutions have imaging protocols in place; however, the use of alternative methods of projection during routine pediatric radiography examinations might heighten current radiation protection guidelines, leading to protocol changes to reduce dose and improve the overall wellbeing of pediatric patients. Furthermore, recent recommendations in the field of medical imaging regarding patient shielding practices might deem positioning to be a more important method for dose reduction. Consultations from radiologists might be necessary to ensure that image quality is sufficient and diagnostic detail is not compromised. Additional training specific to using alternative projections during routine pediatric radiography examinations also might be warranted.
Current practices do not suggest alternative methods of projection are applied regularly during routine pediatric radiography examinations. Considerations should be made to allow technologists to manipulate projections when permitted.
确定放射技师是否在常规儿科放射摄影检查中操纵投照来降低患者剂量。
采用描述性调查方法,随机选择美国放射技师协会的放射技师会员,并邀请他们分享在常规儿科放射摄影检查中使用替代投照的经验。
在这项研究中,分析了 404 份完整的回复。超过一半的参与者(67.6%)强烈或有些同意使用替代投照可以降低常规放射摄影检查中的儿科剂量,超过一半(61.3%)强烈、同意或有些同意使用替代投照对剂量减少有益。顺便说一句,参与者在常规儿科放射摄影检查中使用替代投照的最常见回复是偶尔或有时。近四分之三的参与者强烈认为在常规儿科放射摄影检查中遵循放射防护指南很重要。尽管本研究中的许多放射技师在儿科手术中使用替代投照感到熟练,但他们也认为额外的培训在这些方法中会受益。
大多数机构都有成像协议;然而,在常规儿科放射摄影检查中使用替代投照方法可能会提高当前的放射防护指南,导致协议改变以减少剂量并提高儿科患者的整体健康水平。此外,医学成像领域最近关于患者屏蔽实践的建议可能认为定位是减少剂量的更重要方法。需要咨询放射科医生以确保图像质量足够并且诊断细节不受影响。还可能需要进行专门针对常规儿科放射摄影检查中使用替代投照的额外培训。
目前的做法并没有表明在常规儿科放射摄影检查中经常应用替代投照方法。应考虑允许技术人员在允许的情况下操纵投照。
