摘要

简介：探查或定位射线照片是 CT 成像不可或缺的组成部分。然而，放射技师和放射科医生往往不清楚定位器射线照片的各种功能和作用。本范围审查报告全面介绍了定位器射线照片在当代 CT 成像中的使用范围和功能：方法：进行了范围界定审查。使用四个数据库进行了系统的文献检索：MEDLINE、CINAHL、Emcare 和 Scopus。数据提取由两位综述作者完成，并由第三位综述作者进行验证。本综述共纳入 36 项研究：出现了三大主题：辐射剂量管理、图像质量考虑因素和临床方案应用。具体来说，定位器射线照片的数量、选择顺序和方向会对患者剂量和图像质量产生重大影响；此外，偏离中心的患者定位也会影响患者剂量和图像质量，从而影响体型估计和 CT 数字的准确性。最后，定位器射线照片的最佳选择，包括曝光参数（kVp、mAs），可以成为基于临床任务的成像方案优化的一部分：结论：CT 成像中定位器射线照片的作用多种多样。放射技师和放射科医生必须了解他们的作用以及使用不当的影响，以确保通过正确使用最大限度地减少辐射剂量和提高图像质量。放射技师和放射科医生还应了解患者体位不当对 ACTM 功能、剂量和图像质量的影响。此外，还应将定位器射线照片用于基于临床任务的方案优化：实践意义：在使用定位器射线照片时，必须考虑其数量、选择顺序、方向、患者偏离中心和曝光参数，因为它们会影响剂量、图像质量和方案应用。放射技师和放射医师必须了解这些影响。

Localiser radiographs in CT: Current practice, radiation dose, image quality and clinical applications

Introduction

Survey or localiser radiographs are integral to CT imaging. However, the diverse functions and roles of the localiser radiograph are often obscure to radiographers and radiologists. This scoping review reports the full scope of localiser radiograph use and function in contemporary CT imaging.

Methods

A scoping review was performed. A systematic literature search was conducted using four databases: MEDLINE, CINAHL, Emcare and Scopus from January 2013 to December 2023. Data extraction was conducted by two review authors and validated by a third reviewer. Thirty-six studies were included in this review.

Results

Three major themes emerged: radiation dose management, image quality considerations and clinical protocol applications. Specifically, the number, order of selection and directions of localiser radiographs significantly impact patient dose and image quality; which are additionally impacted by off-centre patient positioning, which can influence the accuracy of body size estimates and CT numbers. Finally, the optimal selection of localiser radiographs, including exposure parameters (kVp, mAs), can be a part of clinical task-based imaging protocol optimisation.

Conclusions

The utilities of localiser radiographs in CT imaging are varied. It is salient that radiographers and radiologists understand their role and the impacts of poor application to ensure that radiation dose is minimised and image quality maximised through correct use. Radiographers and radiologists should also be aware of the impact of poor patient positioning on ACTM function, dose and image quality. Additionally, localiser radiographs should be used for clinical task-based protocol optimisation.

Implications for practice

The number, order of selection, direction, patient off-centring, and exposure parameters must be considered when utilising localiser radiographs as they impact dose, image quality, and protocol applications. It is essential for radiographers and radiologists to understand these impacts.
