Background

Ventricular tachycardia is an irregular heartbeat conventionally treated using invasive cardiac catheter ablation and medication. However, when standard treatments have been exhausted, cardiac SABR provides a final treatment option to this high-mortality condition. Complex diagnostic mapping and planning scans enable multi-disciplinary target delineation for a 25Gy single fraction. However, organs at risk (OAR) near the target make this treatment challenging to plan and deliver. Publications from cardiologists report the efficacy of cardiac SABR, however there is limited data on the treatment delivery and image matching of this complex procedure.

Methods

Four specialist therapeutic radiographers experienced in cardiac SABR reviewed 40 CBCTs from 10 patients treated in the UK. Each therapeutic radiographer conducted five image matches: a manual match (manual), an automatic match to the heart structure (auto) and the auto match followed by manual adjustment to the PTV (PTV), all using three degrees of freedom (DoF) only. The auto and PTV matches were also repeated using 6DoF. Inter-observer variability was quantified using 95% limits of agreement from a modified Bland-Altman analysis.

Results

The limits of agreement were smallest in the automatic matches suggesting the algorithm is reliable. A manual adjustment from the auto match to the PTV is clinically appropriate to optimise target coverage. The limits of agreement were smaller in the 6DoF PTV match 1.06 mm, 1.24 mm, 1.68 mm than the 3DoF PTV match 1.57 mm, 2.06 mm, 2.11 mm (lateral, vertical, longitudinal).

Conclusion

The 6DoF CBCT image match has less variability and therefore suggest using a 6DoF couch for treatment delivery.

Implications for practice

Cardiac SABR CBCT image matching at treatment delivery is complex, optimisation of CBCT acquisition parameters and therapeutic radiographer training is essential prior to implementation.

背景：室性心动过速是一种心律不齐的疾病，传统的治疗方法是采用侵入性心脏导管消融术和药物治疗。然而，在用尽标准治疗方法后，心脏 SABR 为这种死亡率极高的疾病提供了最后的治疗选择。复杂的诊断绘图和规划扫描可为 25Gy 单次分次治疗划定多学科靶点。然而，靶点附近的高危器官（OAR）使这种治疗方法的计划和实施具有挑战性。心脏病专家发表的文章报告了心脏 SABR 的疗效，但有关这种复杂手术的治疗实施和图像匹配的数据却很有限：方法：四名在心脏 SABR 方面经验丰富的专业治疗放射技师对在英国接受治疗的 10 名患者的 40 张 CBCT 进行了审查。每位治疗放射技师进行了五次图像匹配：手动匹配（manual）、自动匹配心脏结构（auto）和自动匹配后手动调整 PTV（PTV），所有匹配均仅使用三个自由度（DoF）。自动匹配和 PTV 匹配也使用 6 自由度重复进行。使用改良的布兰-阿尔特曼分析法得出的 95% 的一致性限值对观察者间的变异性进行量化：结果：自动匹配的一致性极限最小，表明该算法是可靠的。从自动匹配到 PTV 的手动调整在临床上适合优化目标覆盖范围。6DoF PTV匹配1.06毫米、1.24毫米、1.68毫米（横向、纵向、纵向）的一致性极限小于3DoF PTV匹配1.57毫米、2.06毫米、2.11毫米（横向、纵向、纵向）：结论：6DoF CBCT 图像匹配的变异性较小，因此建议使用 6DoF 床进行治疗：实践意义：心脏 SABR CBCT 图像匹配在治疗过程中非常复杂，因此在实施之前，必须优化 CBCT 采集参数并对放射治疗技师进行培训。

Introduction

The international recruitment of healthcare workers remains a UK strategy to manage workforce gaps and maintain service delivery. Although not a new phenomenon, this has been exacerbated by chronic shortages. There is a need to profile the current international recruits and identify individual motivators to understand the opportunities for future recruitment and retention initiatives.

Method

A UK-wide electronic survey was conducted using the Jisc platform. The survey was promoted using social media and researcher networks. Eligibility criteria were diagnostic radiographers, internationally educated, and currently working in the UK.

Results

226 responses were received. Most were working in England (90.7%) and 58.0% were under 35 years of age. The majority had migrated having moved to the UK since 2020 (63.7%) and the main drivers were career and/or training opportunities. Initial education was in 30 different countries, the highest number originating from Africa and Asia, with a median of 6 years post-qualification experience (IQR 4–11yrs). Despite experience, most were employed in band 5 (n = 72) or band 6 posts (n = 95). 56% had postgraduate qualifications on entry and a third had undertaken postgraduate study in the UK.

Conclusion

Based on the survey responses, the profile of internationally recruited diagnostic radiographers is relatively young but with pre-migration experience originating all over the globe. They are motivated to work in the UK particular for career progression opportunities.

Implications for practice

This study provides an insight into the motivations, demographics and employment patterns of internationally recruited radiographers working in the UK.

导言：国际招聘医护人员仍然是英国管理劳动力缺口和维持服务提供的一项战略。尽管这并不是一个新现象，但由于长期短缺，这一现象愈演愈烈。有必要对当前国际招聘人员的概况进行分析，并确定个人动机，以了解未来招聘和留住人才的机会：方法：利用 Jisc 平台在英国范围内开展了一项电子调查。调查利用社交媒体和研究人员网络进行推广。调查对象为接受过国际教育、目前在英国工作的放射诊断技师。大多数人在英国工作（90.7%），58.0%的人年龄在 35 岁以下。大多数人是自 2020 年以来移居英国的（63.7%），主要原因是职业和/或培训机会。初始教育来自 30 个不同国家，其中来自非洲和亚洲的人数最多，获得资格后的工作经验中位数为 6 年（IQR 为 4-11 年）。尽管经验丰富，但大多数人都是在 5 级（n = 72）或 6 级（n = 95）的岗位上工作。56%的人在入职时拥有研究生学历，三分之一的人曾在英国攻读研究生课程：根据调查反馈，国际招聘的放射诊断技师相对年轻，但移民前的工作经验来自全球各地。他们到英国工作的动机主要是为了获得职业发展机会：本研究有助于深入了解在英国工作的国际招聘放射技师的工作动机、人口统计和就业模式。

Objectives

To review and evaluate available literature on spectral computed tomography (SCT) bone mineral density (BMD) measurement in adult thoracolumbar vertebrae of unenhanced images compared to quantitative computed tomography (QCT), to understand its current clinical utility.

Key findings

Keyword searches in four databases identified four cross-sectional studies which acquired an SCT BMD measurement in thoracolumbar vertebrae and compared this respectively to QCT, which were then critically appraised using the AXIS tool for cross-sectional studies. 862 vertebrae were measured between T10-S1 in 368 patients. Three studies demonstrated a statistically significant correlation between SCT and QCT for the measurement of Hydroxyapatite (HAP) and calcium (r = 0.86–0.96). One study demonstrated a diagnostic accuracy of 96% using a receiver operating curve.

Conclusions

SCT measurements of HAP and calcium in the lumbar vertebrae are comparable to QCT for patients with no additional pathology present. However, further research is required to evaluate diagnostic accuracy before clinical application.

Implications for practice

SCT BMD measurement has the potential to be developed as a screening tool for osteoporosis within the fracture liaison service (FLS). This could aid in the identification of patients with osteoporosis and address the current treatment gap. Nonetheless, many factors must be considered for this application including staff training, radiation protection and patient engagement with the screening programme.

目的回顾并评估光谱计算机断层扫描（SCT）与定量计算机断层扫描（QCT）对比测量成人胸腰椎未增强图像的骨矿密度（BMD）的现有文献，以了解其目前的临床实用性：在四个数据库中进行关键词搜索后发现了四项横断面研究，这些研究获得了胸腰椎SCT BMD测量结果，并分别与QCT进行了比较，然后使用横断面研究AXIS工具对这些研究进行了严格评估。对 368 名患者 T10-S1 之间的 862 个椎骨进行了测量。三项研究表明，在测量羟磷灰石（HAP）和钙方面，SCT 和 QCT 之间存在统计学意义上的显著相关性（r = 0.86-0.96）。一项研究利用接收者操作曲线显示诊断准确率为 96%：结论：对于没有其他病变的患者，SCT 测量腰椎的 HAP 和钙的结果与 QCT 相当。然而，在临床应用之前，还需要进一步的研究来评估诊断的准确性：SCT BMD 测量有可能发展成为骨折联络服务（FLS）中的骨质疏松症筛查工具。这有助于识别骨质疏松症患者，解决目前的治疗缺口。然而，这一应用必须考虑许多因素，包括人员培训、辐射防护和患者对筛查计划的参与度。

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.

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。
