Introduction

Tuberculosis (TB) prevalence is considered high amongst refugees and asylum seekers (RAAS). Active TB screening using universal (indiscriminate) chest radiography (CXR) has been adopted in several European countries. Universal CXR screening raises concerns for radiation protection; no existing research reviews the literature from a radiography perspective. This review aims to identify and analyse relevant primary research to discuss the justification of universal CXR for RAAS in an active TB screening context.

Methods

The search strategy included the databases CINAHL, MEDLINE, EMBASE and ScienceDirect and used predefined Boolean search terms and inclusion/exclusion criteria. A critical appraisal evaluated the quality of papers included in the review, and a synthesis-analysis method was used to find common themes.

Results

Eight papers were included in the review. The thematic analysis identified three themes for discussion: the 2014/15 crisis, the complexity of defining TB risk amongst RAAS, and the value of CXR-led versus symptom-led screening for RAAS. Findings support continued systematic screening for TB amongst RAAS but with re-evaluation of CXR eligibility or the screening algorithm.

Conclusions

The heterogeneity of TB risk amongst RAAS indicates that CXR-led screening should be targeted at specific high-risk groups rather than universally applied.

Implications for practice

Justification of CXR screening for RAAS is context-specific and should be informed by TB risk amongst the target population. The advantages of CXR-led screening over other screening algorithms (e.g. symptom-led) justify its use for TB screening in most settings. Considerations identified in this literature review could help inform the development of local protocols for justifying CXR for TB screening amongst RAAS.

导言：在难民和寻求庇护者（RAAS）中，结核病（TB）的发病率被认为很高。一些欧洲国家已采用普遍（无差别）胸片（CXR）对肺结核进行主动筛查。普遍的 CXR 筛查引起了人们对辐射防护的关注；目前还没有研究从放射学的角度对相关文献进行回顾。本综述旨在确定和分析相关的初步研究，以讨论在结核病主动筛查中针对 RAAS 普及 CXR 的合理性。方法：检索策略包括 CINAHL、MEDLINE、EMBASE 和 ScienceDirect 等数据库，并使用预定义的布尔检索词和纳入/排除标准。批判性评价对纳入综述的论文进行了质量评估，并采用综合分析方法寻找共同的主题。专题分析确定了三个讨论主题：2014/15 年度危机、界定 RAAS 中结核病风险的复杂性，以及针对 RAAS 的 CXR 主导型筛查与症状主导型筛查的价值。结论 RAAS 中结核病风险的异质性表明，以 CXR 为主导的筛查应针对特定的高风险人群，而不是普遍应用。对实践的启示对 RAAS 进行 CXR 筛查的理由要视具体情况而定，并应根据目标人群的结核病风险而定。与其他筛查算法（如症状引导）相比，CXR 引导筛查的优势使其有理由在大多数情况下用于结核病筛查。本文献综述中确定的考虑因素有助于为制定当地方案提供参考，以证明在 RAAS 中进行 CXR 肺结核筛查是合理的。

Introduction

The transition to qualified practice for health practitioner graduates can be a challenging experience. Supportive transition to practice programs for graduates are typical in nursing, however they are less common in allied health. Investigations into the transition to practice experience of radiation therapist (RT) graduates specifically have been limited. This study aimed to examine the transition to practice experiences of RT graduates in Australia during their first ten months of qualified practice, with the intention to inform the development of fit for purpose transition to practice programs.

Methods

A longitudinal qualitative study was undertaken employing a constructivist grounded theory methodology. Data collection included an online focus group with RT graduates within their first three months of practice; recording of longitudinal audio diaries for six months; and an individual online interview at ten months of qualified practice.

Results

Seven RT graduates participated in the study during 2022–2023. Central to the transitional process was ‘Becoming the Radiation Therapist’ where graduates worked towards assimilating their emerging professional identity. This process was influenced by ‘Fitting in’ to the team; ‘Navigating expectations’ of work and the workplace; ‘Being supported by experienced others’; and ‘Building confidence’ through validating experiences.

Conclusion

The transitional experience of the RT graduate was influenced by their internal identity work, and by the social and structural mechanisms within their workplace. A transition to practice program should include supportive mentoring, intentional exposure to a breadth of experiences, and clear expectations to assist the RT graduate in navigating this challenging period.

Implications for practice

The transitional experience can be difficult, and supportive mechanisms throughout the first year of graduate practice would aid the emerging professional identity of the RT graduate and their role within the workplace.

导言保健从业人员毕业生向合格执业过渡可能是一个具有挑战性的经历。为毕业生提供过渡到执业阶段的支持计划在护理行业很常见，但在专职医疗行业却不太常见。专门针对放射治疗师（RT）毕业生执业过渡经历的调查还很有限。本研究旨在考察澳大利亚放射治疗师毕业生在获得执业资格的前十个月中的执业过渡经历，以期为制定符合目的的执业过渡计划提供参考。方法采用建构主义基础理论方法开展纵向定性研究。数据收集包括：在实习的前三个月内与康复治疗师毕业生进行在线焦点小组讨论；录制六个月的纵向音频日记；以及在实习期满十个月时进行个人在线访谈。过渡过程的核心是 "成为放射治疗师"，在这一过程中，毕业生努力同化其新兴的职业身份。这一过程受到以下因素的影响："融入 "团队；"驾驭 "对工作和工作场所的期望；"得到有经验的人的支持"；以及通过验证经验 "建立自信"。实习过渡项目应包括支持性指导、有意识地接触广泛的经验以及明确的期望，以帮助康复治疗师毕业生渡过这一具有挑战性的时期。对实践的启示过渡经历可能是困难的，在研究生实习的第一年里，支持性机制将有助于康复治疗师毕业生的职业认同和他们在工作场所中的角色。

Introduction

There has been an increased demand for medical imaging procedures through the years. This demand requires the diagnostic radiographers in the workforce to be equipped with adequate training and understanding of their roles. The aims of this research are to distill and further describe the current scope of practice as established by the Allied Health Professional Council and map the diffusion of tasks, roles and responsibilities within Singapore’s radiography imaging modalities.

Methods

A structured questionnaire was distributed to all diagnostic radiographers in Singapore through emails sent out by the Singapore Society of Radiographers. Information collected included respondents' duties in their respective imaging modalities, the professional tracks they specialised in, and their demographical information. Quantitative data analysis was conducted using SPSS and Fisher’s Exact test of independence was used to determine correlations between variables.

Results

A total of 120 questionnaire responses were obtained and after exclusion, 99 responses were analysed. It was observed that there was a significant positive correlation in radiography experience and performing specialised Computed Tomography examinations (p = 0.005). Additionally, higher radiographer designation was shown to be correlated with the ability to perform more specialised Ultrasound examinations (p < 0.001). The study demonstrated a diverse range of tasks by radiographers which was determined by education, disparity in experience, institutional practice and training provided.

Conclusion

This preliminary study on Singapore diagnostic radiographers provided valuable insight and mapping of their activities in several imaging modalities, allowing for future development of a scope of practice document for Singapore.

Implication for practice

The tasks undertaken by the diagnostic radiographers were integral to imaging service delivery and play a significant role in the advancement of radiography to further enhance the quality of patient care.

导言多年来，人们对医学成像程序的需求不断增加。这种需求要求放射诊断技师接受足够的培训，并了解自己的职责。本研究的目的是提炼并进一步描述新加坡专职医疗人员理事会（Allied Health Professional Council）制定的现行执业范围，并绘制新加坡放射成像模式中任务、角色和职责的分布图。方法通过新加坡放射技师协会（Singapore Society of Radiographers）发送的电子邮件，向新加坡所有放射诊断技师发放结构化问卷。收集的信息包括受访者在各自影像模式中的职责、所擅长的专业领域以及人口统计学信息。使用 SPSS 对数据进行了定量分析，并使用费雪精确检验法确定变量之间的相关性。结果表明，放射学经验与进行专业计算机断层扫描检查之间存在明显的正相关关系（p = 0.005）。此外，放射技师职称越高，就越有能力进行更专业的超声波检查（p = 0.001）。这项关于新加坡放射诊断技师的初步研究提供了有价值的见解，并描绘了他们在几种成像模式中的活动，为今后制定新加坡的执业范围文件提供了依据。对实践的启示放射诊断技师所承担的任务是提供成像服务不可或缺的一部分，对放射学的发展起到了重要作用，从而进一步提高了病人护理的质量。

Background

Workplace violence is associated with anxiety, depression, job dissatisfaction, burnout, absenteeism, staff replacement costs and productivity loss. However, no study has investigated the issue of workplace violence against diagnostic radiographers in Ghana. The aim of this study was to determine the prevalence and factors associated with workplace violence against diagnostic radiographers in Ghana.

Methods

An anonymous, online, nationwide cross-sectional study was conducted from 31st January to 22nd July 2024. The survey contained questions on socio-demographic characteristics, physical violence, verbal abuse, bullying/mobbing, sexual harassment and cultural/ethnic harassment. Binomial and multivariate logistic regression analysis was performed to predict the factors associated with workplace violence. A p-value of less than 0.05 was considered statistically significant.

Results

A total of 209 diagnostic radiographers responded to the online survey. In total, 26.3 % (n = 55/209) of the respondents were within the age group 25–29 years, and 53.6 % (n = 112/209) were males. The 12-month prevalence of workplace violence among the respondents was 93.8 % ([95 % CI: 89.6–96.6]; p < 0.001). The most prevalent forms of workplace violence were verbal abuse (n = 175/209, 83.7 %), physical violence (n = 110/209, 52.6 %) and cultural/ethnic threat (n = 93/209, 44.5 %). Factors significantly linked to experiencing any form of workplace violence in both unadjusted and adjusted models were level of education and being worried about violence.

Conclusion

Workplace violence is common among diagnostic radiographers in Ghana and victims hardly report the incident to the relevant authorities. It is recommended that future research use a qualitative approach to gain a comprehensive understanding of the factors that facilitate or hinder the reporting of workplace violence among diagnostic radiographers.

Implications for practice

Investigating workplace violence could help design and implement multifaceted interventions to ensure safe and healthy working environments for healthcare professionals, including diagnostic and therapeutic radiographers in Ghana.

背景工作场所暴力与焦虑、抑郁、工作不满、职业倦怠、旷工、员工替代成本和生产力损失有关。然而，目前还没有研究调查过加纳放射诊断技师遭受工作场所暴力的问题。本研究旨在确定加纳放射诊断技师在工作场所遭受暴力的发生率和相关因素。调查内容包括社会人口特征、身体暴力、辱骂、欺凌/聚众闹事、性骚扰和文化/种族骚扰等问题。为预测与工作场所暴力相关的因素，进行了二项式和多变量逻辑回归分析。结果共有 209 名放射诊断技师回复了在线调查。其中 26.3% 的受访者（n = 55/209）年龄在 25-29 岁之间，53.6% 的受访者（n = 112/209）为男性。受访者在 12 个月内的工作场所暴力发生率为 93.8 %（[95 % CI: 89.6-96.6]; p < 0.001）。最普遍的工作场所暴力形式是辱骂（n = 175/209，83.7%）、肢体暴力（n = 110/209，52.6%）和文化/种族威胁（n = 93/209，44.5%）。在未调整模型和调整模型中，与遭受任何形式的工作场所暴力有明显联系的因素是教育水平和对暴力的担忧。建议今后的研究采用定性方法，以全面了解促进或阻碍放射诊断技师报告工作场所暴力事件的因素。对实践的启示调查工作场所暴力事件有助于设计和实施多方面的干预措施，以确保医疗保健专业人员（包括加纳的放射诊断和治疗技师）享有安全和健康的工作环境。

Introduction

Radiological investigations for epiphora often use techniques involving ionising radiation and may require invasive canalicular cannulation.

Magnetic resonance dacryocystography (MRDCG) has been explored but is currently not widely utilised in clinical imaging departments.

The aim of this technical report is to describe the optimisation of a non-invasive MRDCG technique using a continuous gadolinium drip to assess the anatomy and real-time functionality of the nasolacrimal drainage system (NLDS).

Methods

A protocol was developed on a 1.5 Tesla (1.5 T) magnetic resonance imaging (MRI) scanner using a 32-channel head coil.

Coronal and axial T2-weighted sequences demonstrated the anatomy of the NLDS region. An automated slow drip infusion of gadolinium contrast media, diluted with saline (1:100), was delivered simultaneously to both eyes during a two-dimensional (2D) dynamic acquisition. Post-instillation, a three-dimensional (3D) T1-weighted sequence confirmed the presence or absence of contrast media in the NLDS.

Results

Clear visualisation of the anatomy and real-time contrast flow through the NLDS were achieved in 85 % of cases.

Conclusion

This non-invasive MRDCG technique can provide both anatomical and functional evaluation of the NLDS in under 30 minutes. Further work is needed to compare MRDCG findings to more established methods such as DCG and DSG.

导言：针对眼睑外翻的放射检查通常使用涉及电离辐射的技术，并且可能需要进行侵入性的管状插管。磁共振泪囊造影术（MRDCG）已经得到探索，但目前尚未在临床影像科室广泛使用。本技术报告旨在描述使用持续钆滴注的无创 MRDCG 技术的优化情况，以评估鼻泪管引流系统（NLDS）的解剖结构和实时功能：在使用 32 通道头部线圈的 1.5 特斯拉（1.5 T）磁共振成像（MRI）扫描仪上制定了一套方案。冠状和轴向 T2 加权序列显示了 NLDS 区域的解剖结构。在进行二维（2D）动态采集时，用生理盐水（1:100）稀释的钆对比剂自动缓慢滴注到双眼。注入后，三维（3D）T1 加权序列确认了 NLDS 中是否存在造影剂：结果：85%的病例解剖结构清晰可见，造影剂实时流经 NLDS：这种无创 MRDCG 技术可在 30 分钟内对 NLDS 进行解剖和功能评估。还需要进一步将 MRDCG 结果与 DCG 和 DSG 等更成熟的方法进行比较。

Introduction

Student experience impacts outcomes in Higher Education (HE) and has become a focus of interest in ethnicity awarding gap research. The awarding gap is attributed to a range of factors, many of which occur as a result of institutionalised racism. Limited data is available on the experiences of ethnically diverse allied health professionals’ students and none in therapeutic radiography (TR).

Methods

An online survey featuring quantitative and open-ended questions was sent to fourteen universities as phase 1 of a sequential explanatory mixed methods study. The survey was developed from student collaboration and the evidence base, exploring the experiences of university and clinical placement in radiotherapy undergraduate programmes. Themes of “university and clinical placement learning,” “drivers of success and pressure” “racism and microaggressions” and “perceptions of the profession” were examined.

Results

Forty-three responses were received from students recruited via purposive sampling and self-identifying as belonging to an ethnically diverse background. Positive experiences of university and clinical placements were seen but a lower sense of belonging was reported within clinical placement. Sources of support were identified in lecturers, peers, and family. In contrast, family was also identified as a source of pressure. Incidents of racism and microaggressions were reported in clinical and university learning environments, but more frequently seen in the placement setting, and attributed to come from both radiographers and patients.

Conclusion

This study indicates that whilst there were frequent positive aspects of university and clinical placement, racialised incidents occurred, impacting the student experience. Clinical placement providers should focus on enhancing belonging, with academic staff supporting radiographers in inclusive teaching practices.

Implications for practice

All involved in radiography education must act as allies in calling out incivility, racism, and microaggressions, to support and enhance student experience.

导言：学生的经历影响着高等教育（HE）的成果，并已成为种族奖励差距研究的关注焦点。造成这种差距的因素很多，其中许多是制度化的种族主义造成的。有关不同种族的专职医疗专业学生的经历的数据十分有限，而且没有关于治疗放射学（TR）的数据：方法：向 14 所大学发送了一份在线调查，其中包括定量和开放式问题，这是一项顺序解释性混合方法研究的第一阶段。该调查是在学生合作和证据基础上开发的，旨在探索放射治疗本科课程中大学和临床实习的经验。调查的主题包括 "大学和临床实习学习"、"成功的驱动因素和压力"、"种族主义和微观偏见 "以及 "对专业的看法"：通过有目的的抽样调查，共收到 43 份来自自称具有不同种族背景的学生的回复。学生们对大学和临床实习都有积极的体验，但对临床实习的归属感较低。讲师、同学和家人都是支持学生的源泉。相反，家庭也被认为是压力的来源。据报告，在临床和大学学习环境中都存在种族主义和微观诽谤事件，但在实习环境中出现的频率更高，而且这些种族主义和微观诽谤事件既来自放射技师，也来自病人：本研究表明，虽然大学和临床实习中经常出现积极的方面，但种族事件时有发生，影响了学生的体验。临床实习机构应注重增强学生的归属感，学术人员应在包容性教学实践中为放射技师提供支持：实践启示：所有参与放射学教育的人员都必须以盟友的身份呼吁不文明行为、种族主义和微观诽谤，以支持和改善学生的体验。

Introduction

The radiology department plays an important role in healthcare settings, facilitating diagnoses using different imaging modalities, including ultrasound. However, this high-tech environment can pose various risks to patients. In this study, we aimed to describe the risk of patient safety incidents, and factors associated with the prevention of risks related to ultrasound examinations and the diagnostic work, from the perspective of Swedish radiographers.

Methods

We conducted a qualitative study, based on the written answers to three open-ended questions addressed to Swedish radiographers in ultrasound units of radiology departments, between March 2022 and May 2023. Data from the responses were analyzed using content analysis.

Results

A total of 22 radiographers participated in this study. The described risks were categorized into two groups: risk of tissue damage; and risk of missed, delayed, or incorrect diagnoses. Participants stated that patient safety relied on good organizational conditions—such as having enough time for ultrasound examinations and the diagnostic work, together with adequate technical equipment and new ultrasound devices not older than 5 years. As risk-prevention factors, the radiographers recommended ensuring adequate individual competence—for example, through recurrent mandatory education in ultrasound physics and safety performed by the hospital physicist, and by implementing a certificate with an identified level of expertise at every level of the ultrasound examination.

Conclusions

Within ultrasound units in Sweden, collaborative individual, organizational, and technical factors are important for reducing the risks of tissue damage and of missed, delayed, or incorrect diagnoses.

Implications for practice

In ultrasound diagnostics, risk-preventing factors include the use of adequate technical equipment and ultrasound devices not older than 5 years, sufficient time for ultrasound examinations and diagnostic work, thoroughly education in all ultrasound methods and recurrent mandatory education in ultrasound physics performed by hospital physicists.

简介放射科在医疗机构中发挥着重要作用，它利用不同的成像模式（包括超声波）为诊断提供便利。然而，这种高科技环境会给患者带来各种风险。在这项研究中，我们旨在从瑞典放射技师的角度描述患者安全事故的风险，以及与超声波检查和诊断工作相关的风险预防因素：我们在 2022 年 3 月至 2023 年 5 月期间对放射科超声室的瑞典放射技师提出的三个开放式问题进行了书面回答，并在此基础上开展了一项定性研究。研究采用内容分析法对回答的数据进行了分析：共有 22 名放射技师参与了这项研究。所描述的风险分为两类：组织损伤风险和漏诊、延误或错误诊断风险。参与者表示，患者安全有赖于良好的组织条件，例如有足够的时间进行超声波检查和诊断工作，以及充足的技术设备和不超过 5 年的新超声波设备。作为风险预防因素，放射技师建议确保个人具备足够的能力--例如，由医院物理学家定期开展超声物理和安全方面的必修教育，并在超声检查的每个级别上颁发具有明确专业水平的证书：结论：在瑞典的超声波科室中，个人、组织和技术因素对于降低组织损伤风险以及漏诊、延误或错误诊断的风险非常重要：在超声诊断中，预防风险的因素包括使用适当的技术设备和使用年限不超过 5 年的超声设备、为超声检查和诊断工作提供充足的时间、对所有超声方法进行全面教育，以及由医院物理学家对超声物理学进行经常性的强制性教育。

Introduction

American Association of Physicists in Medicine (AAPM) Task Group (TG) 238 provides guidance on quality control procedures to ensuring optimal three-dimensional rotational angiography (3DRA) image quality. The uniformity test outlined in this guideline utilizes a sampling method, which provide limited information on image uniformity and has been found to be a sub-optimum predictor of image quality issues. Despite this limitation, numerous automated quality control software solutions for uniformity testing have been developed using the available method. Therefore, this study was aimed to propose new methods as well as to develop an in-house software to generate more comprehensive uniformity testing of 3DRA images.

Methods

The uniformity evaluation techniques are adopted from both AAPM TG-238 guidelines and the European Reference Organisation for Quality Assured Breast Screening and Diagnostic Services (EUREF) guidelines. The parameters assessed included mean pixel value (MPV) and signal to noise ratio (SNR) following EUREF recommendations with limiting values adapted from AAPM TG-238. An in-house software was constructed to visually display non-uniformities and numerically by providing information on ROIs detected by each metric.

Results

With the introduction of new evaluation methods, the previously established limiting values could not be employed as a reference for determining image uniformity. Therefore, the selection of the optimal uniformity testing method will be based on its sensitivity in detecting and visually displaying non-uniformities.

Conclusion

The new evaluation techniques provide a more comprehensive assessment of 3DRA image uniformity. However, further investigation is reserved to refine the limitation values used in determining the pass/fail criteria for the uniformity test.

Implications for practice

This in-house software enables visualization of uniformity within an image, aiding in the selection of the appropriate imaging mode based on clinical requirements.

导言：美国医学物理学家协会（AAPM）第 238 工作组（TG）为质量控制程序提供指导，以确保最佳的三维旋转血管造影（3DRA）图像质量。该指南中概述的均匀性测试使用的是抽样方法，这种方法只能提供有限的图像均匀性信息，而且已被发现不是预测图像质量问题的最佳方法。尽管存在这一局限性，但仍有许多自动质量控制软件解决方案利用现有方法进行了均匀性测试。因此，本研究旨在提出新的方法，并开发一款内部软件，对 3DRA 图像进行更全面的均匀性测试：均匀性评估技术采用了 AAPM TG-238 指南和欧洲质量保证乳腺筛查和诊断服务参考组织 (EUREF) 指南。评估的参数包括平均像素值 (MPV) 和信噪比 (SNR)，均遵循 EUREF 的建议，而极限值则参照 AAPM TG-238 的规定。我们开发了一款内部软件来直观显示非均匀性，并通过提供每个指标检测到的 ROI 的信息来计算非均匀性：结果：随着新评估方法的引入，以前确定的极限值不能作为确定图像均匀性的参考。因此，选择最佳的均匀性检测方法将基于其在检测和直观显示非均匀性方面的灵敏度：结论：新的评估技术能更全面地评估 3DRA 图像的均匀性。结论：新的评估技术能更全面地评估 3DRA 图像的均匀性，但仍需进一步研究，以完善用于确定均匀性测试通过/失败标准的限制值：这款内部软件可实现图像内均匀性的可视化，有助于根据临床要求选择合适的成像模式。

Introduction

In Denmark, there are no official guidelines on how to inform women about the risk of recall during mammography screening, leading to varied local practices. This study explored the experiences of radiographers at a Danish mammography screening unit and breast cancer assessment clinic communicating the risk of recall and false-positive results.

Methods

This study involved 12 weeks of ethnographic fieldwork over the course of one year, along with eleven semi-structured interviews with radiographers.

Results

Radiographers worked at the screening unit and the breast cancer assessment clinic. This provided them an opportunity to learn from their colleagues, improve communication skills, and the ability to recognise and respond to emotional reactions. The radiographers were aware that recalls might cause psychosocial consequences and had thus established a local practice sensitive to this. The radiographers informed women at their first screening about the risk of recall and false positives, aiming to mitigate these consequences.

Conclusion

These findings highlight the advantages of radiographers working in both screening and clinical settings.

Implications for practice

Insights from this study may inspire future guidelines or local screening practices and improve patient care. Furthermore, results may inform department managers’ workload organisation.

导言：在丹麦，关于如何告知妇女乳腺 X 射线摄影筛查中的召回风险并没有官方指南，因此当地的做法各不相同。本研究探讨了丹麦一家乳腺 X 射线照相筛查机构和乳腺癌评估诊所的放射技师在告知回访风险和假阳性结果方面的经验：本研究在一年内进行了为期 12 周的人种学实地调查，并对放射技师进行了 11 次半结构化访谈：结果：放射技师在筛查单位和乳腺癌评估诊所工作。这为他们提供了向同事学习的机会，提高了沟通技巧以及识别和应对情绪反应的能力。放射技师们意识到召回可能会造成社会心理后果，因此在当地建立了对这一问题敏感的做法。放射技师在妇女第一次筛查时就告知她们召回和假阳性的风险，旨在减轻这些后果：这些发现凸显了放射技师在筛查和临床环境中工作的优势：本研究的启示可能会对未来的指南或当地筛查实践有所启发，并改善患者护理。此外，研究结果还可为科室管理人员的工作量安排提供参考。
