Introduction

The clinical environment can be intimidating for first-year university students, particularly those without prior exposure through job shadowing. A student’s first hospital experience is therefore crucial in shaping motivation and commitment to their chosen career path. Traditional hospital orientation, often limited to passive departmental tours led by supervisors, may fail to actively engage students or leave a lasting impression. The Amazing Radiography Race (ARR) introduces a gamified alternative, engaging students in group-based clue solving and task completion tailored to each radiography department. This study aims to explore students’ experiences of the ARR, captured through reflective report writing

Methods

The study was conducted at a University in South Africa. The study population is 60 first-year radiography students, selected through a purposive sampling method. Data was collected prospectively using reflective reports guided by the six steps of Gibbs’ reflective cycle, which includes, 1) description, 2) feelings, 3) evaluation, 4) analysis, 5) conclusion, and 6) action plan. Content analysis was used to analyse the data.

Results

Five main themes were developed: 1) Positive affective experiential learning 2) Introduction to foundational radiographic principles, 3) Insight into the reality of the clinical environment and career progression, 4) Learning through peer-mentorship and 5) Improvement of game dynamics. The students’ reflections indicate that the ARR had a multitude of benefits that the students could use to build on as they start their first year of study

Conclusion

The Amazing Radiography Race demonstrates the value of gamification in health science orientation, promoting self-directed learning, teamwork, and essential interpersonal skills. It provided meaningful exposure for students with limited preclinical experience and highlighted the critical role of enthusiastic facilitators, especially senior students, in creating a supportive learning environment. While clinical settings may pose challenges, the ARR offers a scalable, context-sensitive model for enhancing orientation across disciplines.
临床环境对大学一年级的学生来说可能是令人生畏的,尤其是那些没有通过工作见习接触过的学生。因此,学生的第一次医院经历对于形成他们选择的职业道路的动机和承诺至关重要。传统的医院迎新活动通常仅限于由主管领导的被动部门参观,可能无法积极吸引学生或留下持久的印象。惊人的放射摄影比赛(ARR)引入了一个游戏化的替代方案,让学生参与到以小组为基础的线索解决和任务完成中,为每个放射摄影部门量身定制。本研究旨在探索学生的ARR经历,通过反思性报告写作方法:该研究在南非的一所大学进行。研究人群为60名一年级放射学专业的学生,通过有目的的抽样方法选择。在吉布斯反思周期的六个步骤指导下,前瞻性地使用反思报告收集数据,其中包括:1)描述,2)感受,3)评估,4)分析,5)结论,6)行动计划。采用内容分析法对数据进行分析。结果:本研究发展了五个主要主题:1)积极情感体验学习;2)放射学基本原理介绍;3)临床环境和职业发展的现实洞察;4)通过同伴指导学习;5)游戏动力学的改进。学生们的反思表明,ARR有很多好处,学生们可以在他们开始第一年的学习时利用这些好处。结论:惊人的放射摄影比赛展示了游戏化在健康科学方向上的价值,促进了自主学习、团队合作和基本的人际交往能力。它为临床前经验有限的学生提供了有意义的接触,并强调了热情的促进者,特别是高年级学生,在创造支持性学习环境方面的关键作用。虽然临床环境可能会带来挑战,但ARR提供了一个可扩展的、环境敏感的模型,以加强跨学科的定位。

Purpose

Advancements in precision radiation therapy have enabled adaptive radiation therapy (ART), which involves modifying treatment plans based on anatomical changes observed during treatment. This study analyzes ART workflows and Radiation Therapist (RTT) roles to identify upskilling needs and inform recommendations for a national competency framework supporting advanced image-guided ART in Canada.

Materials and Methods

A multi-center, multi-phase mixed methods approach was used to explore RTT roles and training needs for ART across Canada. Phase 1 analyzed national survey data, focusing on RTT involvement and training in offline and online ART workflows. Phase 2 mapped online ART workflows for MR-guided and CT-guided linac systems and compared them to national and international competency frameworks. Phase 3 employed a Modified Delphi process with subject matter experts from five Canadian centers practicing online ART to reach consensus on tasks requiring upskilling beyond entry-level competencies.

Results

Survey responses were received from 32 of 48 centers (67%), with 25 reporting offline ART and 5 reporting online ART. RTTs were involved in nearly all steps of both ART workflows, though their roles varied by modality. Offline ART tasks were primarily performed by dosimetry RTTs, while online ART tasks were concentrated among treatment unit RTTs. Training approaches differed significantly, with offline ART relying on in-house methods and online ART initially supported by vendor training. The Delphi process identified four key tasks requiring upskilling: structure propagation and contouring, target volume verification, plan modification, and dosimetric evaluation. These tasks, along with treatment decision-making, were also rated as highly important to the safety and efficacy of online ART.

Conclusions

Canadian RTTs are increasingly taking on expanded roles in the ART process. However, for those stepping into these roles, training has been inconsistent and often lacking beyond entry-level preparation. Tasks identified by expert consensus should serve as target training areas for centers aiming to upskill their RTTs and broaden the implementation of ART. An adaptive competency framework could equip RTTs with the necessary knowledge, skills and judgement to successfully work in this evolving ART environment and should standardize training nationally.
目的:精确放射治疗的进步使适应性放射治疗(ART)成为可能,它涉及根据治疗期间观察到的解剖变化修改治疗计划。本研究分析了ART工作流程和放射治疗师(RTT)的角色,以确定技能提升需求,并为支持加拿大先进图像引导ART的国家能力框架提供建议。材料和方法:采用多中心、多阶段混合方法探讨RTT在加拿大ART中的作用和培训需求。第一阶段分析了国家调查数据,重点关注RTT参与和线下和在线ART工作流程的培训。第二阶段绘制了核磁共振引导和ct引导直线系统的在线ART工作流程,并将其与国家和国际能力框架进行了比较。第三阶段采用了改进的德尔福流程,来自五个加拿大中心的主题专家进行在线ART实践,以就需要提高入门级技能的任务达成共识。结果:48个中心中有32个(67%)收到了调查回复,其中25个报告了线下ART, 5个报告了在线ART。rtt参与了ART工作流程的几乎所有步骤,尽管它们的作用因形式而异。离线ART任务主要由剂量学rtt完成,而在线ART任务集中在治疗单位rtt中。培训方法差异很大,离线ART依赖于内部方法,而在线ART最初由供应商培训支持。德尔福过程确定了需要提高技能的四个关键任务:结构传播和轮廓,目标体积验证,计划修改和剂量学评估。这些任务以及治疗决策也被认为对在线抗逆转录病毒治疗的安全性和有效性非常重要。结论:加拿大rtt在ART治疗过程中发挥的作用越来越大。然而,对于那些进入这些角色的人来说,培训一直不一致,而且往往缺乏入门级的准备。专家共识确定的任务应作为旨在提高其抗逆转录病毒治疗人员技能和扩大抗逆转录病毒治疗实施范围的中心的目标培训领域。适应性能力框架可以为rtt提供必要的知识、技能和判断力,使其在这种不断变化的抗逆转录病毒治疗环境中成功工作,并应使全国培训标准化。

简介:CT肺血管造影(CTPA)是检测肺栓塞的参考标准。然而,它与大量辐射暴露和使用碘造影剂有关,这对患者有固有的风险。随着对患者安全和遵守ALARA(尽可能低的合理可达到)原则的日益重视,优化CTPA方案以最小化辐射剂量和造影剂已成为临床影像学的关键焦点。本系统综述和荟萃分析旨在评估CTPA低管电压和降低造影剂体积方案对辐射剂量、造影剂使用、图像质量和诊断准确性的影响,并确定临床实践中优化这些参数的循证策略。方法:本综述遵循系统评价和荟萃分析的首选报告项目(PRISMA)指南。我们对PubMed、Embase、Scopus、Web of Science和CINHAL进行了系统搜索,以确定研究CTPA中剂量减少和对比节省技术的研究。符合条件的研究报告了辐射暴露、造影剂体积和图像质量的定量结果。两名审稿人独立筛选标题、摘要和全文,进行数据提取,并使用经过验证的偏倚风险工具(QUADS-2)评估方法学质量。当数据足够同质时,进行荟萃分析综合,并进行亚组分析以探索异质性的来源。结果:检索到148条记录,其中35项研究被纳入数据提取,其中11项研究提供了完整的辐射剂量、对比体积和图像质量数据。研究一致表明,使用低管电压(≤80 kVp)和降低造影剂(≤60 ml)的方案,特别是与迭代重建技术(例如,SAFIRE, iDose4)相结合,在保持诊断图像质量的同时,显著降低了计算机断层扫描剂量指数(CTDIvol)和有效剂量,范围从50%到80%以上。图像参数如衰减、信噪比和对比噪声比保持在可接受的诊断范围内,支持低剂量方案的有效性。结论:低kvp CTPA方案减少造影剂体积和迭代重建显著降低辐射和造影剂暴露,而不影响诊断性能。这些发现支持将其纳入常规实践,特别是对于有造影剂肾病或放射敏感性风险的患者。实践意义:使用低管电压CTPA方案,降低造影剂体积,特别是与迭代重建相结合,通过最大限度地减少辐射暴露和造影剂引起的风险,提高了患者的安全性。

Objective

Exposure to low doses of radiation from medical imaging continues to increase over time. Amongst various imaging modalities, radiation from Computed Tomography (CT) scans mainly delivers doses to organs within the field of scan, which can increase the risk of cancer. Therefore, in the present study, we aim to derive the organ dose and estimate the Lifetime Attributable Risk (LAR) of cancer incidence for South Indian pediatric participants receiving radiation during whole abdomen, urogram, chest, and brain CT scans.

Methods

Pediatric participants (n = 100) who underwent different types of CT scans were recruited. The study participants were categorized into four sub-groups based on their age: 0–2.5, 2.5–7.5, 7.5–12.5, and 12.5–18 years. Organ doses were calculated by entering scan parameters in the VirtualDose™ CT software. Cancer risk models in Biological Effects of Ionizing Radiation VII phase 2 report were used to estimate LAR.

Results

The highest organ doses were observed in the colon, stomach, bladder, and liver from whole abdomen CT; bladder, colon, gonads, stomach, breast (females), and liver from urogram CT; lungs, liver, stomach, and breast (females) from chest CT; and salivary glands and brain from brain CT. Predicted LAR of cancer incidence was highest for the colon (58.55) and bladder (35.76) from whole abdomen CT, colon (67.23), bladder (49.37), and breast (females) (46.25) from urogram CT, breast (females) (76.69) and lungs (73.34) from chest CT, and thyroid (16.43) from brain CT, with gonads and thyroid showing the lowest LAR across most scans except brain CT scan.

Conclusion

The present study provides a clearer comprehension of the organ dose and its contribution in estimating the LAR of cancer incidence from a single CT scan, thereby indicating the importance of radiation safety to avoid unwanted exposure in pediatric participants.
目的:暴露于低剂量辐射的医疗成像持续增加的时间。在各种成像方式中,计算机断层扫描(CT)的辐射主要向扫描范围内的器官提供剂量,这可能增加癌症的风险。因此,在本研究中,我们的目的是得出器官剂量,并估计南印度儿童参与者在全腹部、尿路图、胸部和脑部CT扫描时接受辐射的癌症发病率的终生归因风险(LAR)。方法:招募接受不同类型CT扫描的儿童参与者(n = 100)。研究参与者根据年龄分为四组:0-2.5岁、2.5-7.5岁、7.5-12.5岁和12.5-18岁。通过在VirtualDose™CT软件中输入扫描参数来计算器官剂量。使用电离辐射生物学效应第VII期报告中的癌症风险模型来估计LAR。结果:全腹CT显示,结肠、胃、膀胱、肝脏器官剂量最高;膀胱、结肠、性腺、胃、乳房(女性)和肝脏的尿路CT;胸部CT显示肺、肝、胃和乳房(女性);以及脑部CT上的唾液腺和脑部全腹CT预测LAR发生率最高的是结肠(58.55)和膀胱(35.76),尿路CT预测结肠癌(67.23)、膀胱(49.37)和乳房(女性)(46.25),胸部CT预测乳房(76.69)和肺部(73.34),颅脑CT预测甲状腺(16.43),除颅脑CT外,生殖腺和甲状腺的LAR最低。结论:本研究更清楚地了解了器官剂量及其对估计单次CT扫描癌症发生率的贡献,从而表明辐射安全对于避免儿童参与者的不必要暴露的重要性。

Introduction

Gamification in higher education, particularly in the health professions, is rapidly gaining interest. Limited literature, however, prevails over the experiences of educators and students on the development of and participation in gamified assessments. The current paper presents an overview of a newly integrated gamified assessment in an undergraduate medical imaging and therapeutic sciences curriculum and its potential to serve as an assessment tool.

Method

Following ethical approval, the Gibbs Reflective Cycle was utilised among two South African educators and two students from a single research site to reflect on a newly integrated gamified assessment. The Gibbs Reflective Cycle follows a six-phase approach to guide original thought. The six phases included a description of their experience, feelings, an evaluation, an analysis to make sense of the experience by consulting relevant literature, a conclusion, and the development of an action plan to implement potential improvements going forward.

Results and discussion

Similar perspectives were shared between the two educators and two students, reiterating the value of gamification in higher education. Recommendations to enhance the facilitation of similar assessments include, but are not limited to: a physical space that is conducive to playing tangible games, drawing on the working principles of existing games, and a collaborative approach to develop a peer evaluation marking rubric.

Conclusion

The collaborative and reflective approach between the two educators and two students harnessed collective wisdom on the impact of gamification in higher education. Gamified assessments have the potential to improve student engagement, motivation, and learning outcomes. Insight gained into the newly integrated gamified assessment could be used and transferred to curricular offerings in other health professions and beyond.
游戏化在高等教育中,特别是在卫生专业中,正迅速引起人们的兴趣。然而,有限的文献压倒了教育工作者和学生在游戏化评估的发展和参与方面的经验。本文概述了本科医学成像和治疗科学课程中新集成的游戏化评估及其作为评估工具的潜力。方法:在伦理批准后,吉布斯反思周期在两名南非教育工作者和两名来自单一研究站点的学生中使用,以反思新整合的游戏化评估。吉布斯反思周期遵循六个阶段的方法来指导原创思想。这六个阶段包括描述他们的经历、感受、评估、通过查阅相关文献来分析经历、结论、制定行动计划以实施未来可能的改进。结果和讨论:两位教育工作者和两位学生分享了相似的观点,重申了游戏化在高等教育中的价值。促进类似评估的建议包括,但不限于:一个有利于玩有形游戏的物理空间,借鉴现有游戏的工作原理,以及采用合作方法来制定同行评估评分标准。结论:两名教育工作者和两名学生之间的合作和反思方法利用了集体智慧来研究游戏化对高等教育的影响。游戏化评估有可能提高学生的参与度、积极性和学习成果。在新整合的游戏化评估中获得的见解可以用于并转移到其他卫生专业及其他领域的课程中。
