Introduction

Salivary gland dysfunction is a common side effect of radioiodine-131 (ˆ131I) therapy for differentiated thyroid cancer (DTC). We hypothesized that early repeated acid stimulation during Tc-99m salivary gland scintigraphy would reduce radioactive tracer accumulation in salivary glands.

Methods

Eighty-one post-thyroidectomy patients with DTC were assigned to three equal groups: control (no acid stimulation), single stimulation at 2 h post-injection, and early repeated stimulation every 30 min after Tc-99m Pertechnetate (^99mTcO₄^-) injection. ^99mTcO₄^- salivary gland scintigraphy was performed with regions of interest delineated for bilateral parotid and submandibular glands. Time-activity curves were generated over 2.5 h, and radioactivity counts and accumulation ratios were calculated at defined intervals.

Results

Baseline parotid and submandibular radioactivity counts did not differ significantly across groups (parotid: P > 0.05; submandibular: P > 0.05). Both acid stimulation protocols induced significant reductions in glandular radioactivity compared with control at all dynamic acquisition intervals (P < 0.001). Cumulative tracer accumulation was significantly lower in the early repeated stimulation group versus the control and single-stimulation groups (P < 0.001). At the same time, no significant difference was observed between control and single-stimulation groups.

Conclusion

Early repeated acid stimulation markedly decreases ^99mTcO₄^- uptake and retention in salivary glands, outperforming delayed single stimulation.

Implications for practice

Implementing early repeated acid stimulation during 131I therapy may help prevent salivary gland injury and preserve gland function in DTC patients.

涎腺功能障碍是放射性碘-131 （131I）治疗分化型甲状腺癌（DTC）的常见副作用。我们假设Tc-99m唾液腺闪烁成像期间早期重复酸刺激会减少唾液腺中放射性示踪剂的积累。方法将81例甲状腺切除术后DTC患者分为对照组（无酸刺激）、注射后2 h单次刺激和注射Tc-99m高技术酸盐（99mTcO4-）后每30 min早期重复刺激3组。99mTcO4-唾液腺闪烁显像对双侧腮腺和颌下腺划定感兴趣的区域。在2.5 h内生成时间-活度曲线，并在规定的间隔内计算放射性计数和积累比。结果各组腮腺和下颌骨基线放射性计数差异无统计学意义（腮腺：P >； 0.05；下颌骨：P >； 0.05）。与对照组相比，在所有动态采集间隔，两种酸刺激方案都显著降低了腺体放射性（P < 0.001）。与对照组和单次刺激组相比，早期重复刺激组的累积示踪剂积累显著降低（P < 0.001）。与此同时，对照组和单刺激组之间无显著差异。结论早期反复酸刺激可显著降低小鼠唾液腺对99mTcO4-的吸收和滞留，优于延迟单次酸刺激。实践意义在131I治疗过程中，早期重复酸刺激可能有助于预防唾液腺损伤和保护DTC患者的腺体功能。

Introduction

Implementation and practice compliance of preliminary clinical evaluation (PCE) vary across national and international settings. The reason for these variations remains unclear, especially in relation to cross-sectional imaging. This study therefore explored PCE education and practice experiences of a multinational cohort of cross-sectional imaging radiographers with the aim of identifying effective training and implementation strategies, challenges, and opportunities for improvement.

Methods

A phenomenological qualitative design was used, with purposive sampling to recruit a multinational cohort of cross-sectional imaging radiographers enrolled in a UK-based postgraduate medical imaging programme. Semi-structured, in-depth interviews were conducted via Microsoft Teams between December 2024 and February 2025. Data were analysed using Braun and Clarkes’ reflexive thematic analysis approach, facilitated by NVivo™ (v.20.0).

Results

Twelve radiographers from seven different countries participated in the study. The clinical experience of participants ranged (2–8 years), with most working in public or both public and private hospitals (8/12, 67 %) and (5/12, 42 %) had multinational clinical experience. All participants had PCE as a core component of their undergraduate training, but post-qualification practice expectations vary. Four overarching themes were developed: (1) education and skill refinement, (2) drivers for practice, (3) barriers to practice, and (4) opportunities for practice.

Conclusion

The findings reveal inconsistencies in PCE education, including variable module content and teaching depth, which affect clinical preparedness and confidence. Additionally, systemic barriers and communication lapses hinder PCE integration, while engagement is driven by its perceived value for others, support for clinical decision-making and presence of PCE-specific practice frameworks.

Implications for practice

Standardisation of PCE education and training, establishment of clear practice frameworks and addressing communication gaps can enhance the integration of PCE into routine clinical workflows.

简介：临床初步评估（PCE）的实施和实践依从性因国家和国际环境而异。这些变化的原因尚不清楚，特别是与横断面成像有关。因此，本研究探讨了一组跨国横断面成像放射技师的PCE教育和实践经验，旨在确定有效的培训和实施策略、挑战和改进的机会。方法：采用现象学定性设计，有目的抽样，招募一组参加英国研究生医学影像学课程的跨国横断面成像放射技师。在2024年12月至2025年2月期间，通过微软团队进行了半结构化的深度访谈。数据分析使用Braun和Clarkes的反思性主题分析方法，并使用NVivo™（v.20.0）。结果：来自7个不同国家的12名放射技师参与了这项研究。参与者的临床经验范围为（2-8年），大多数在公立或公立和私立医院工作（8/ 12,67 %），（5/ 12,42 %）具有多国临床经验。所有参与者都将PCE作为其本科培训的核心组成部分，但获得资格后的实践期望各不相同。研究发展了四个主要主题：(1)教育和技能改进；(2)实践的驱动因素；(3)实践的障碍；(4)实践的机会。结论：PCE教育的不一致性，包括模块内容和教学深度的变化，影响了临床准备和信心。此外，系统性障碍和沟通失误阻碍了PCE整合，而参与是由其对他人的感知价值、对临床决策的支持以及PCE特定实践框架的存在所驱动的。对实践的影响：PCE教育和培训的标准化，建立明确的实践框架和解决沟通差距可以加强PCE融入常规临床工作流程。

Introduction

Ionising radiation is used extensively in medical imaging and has a demonstrated risk of causing cancer. However, the random nature of stochastic risks has resulted in ionising radiation risks being poorly disclosed to patients. This undermines the validity of a patient's provided informed consent, as without understanding stochastic risks, the consent is not informed.

This systematic review seeks to provide a risk disclosure framework for practitioners by identifying an ideal protocol to disclose stochastic risks by considering the generalisability of advocated informed consent protocols from various medical fields.

Methods

This systematic review searched three electronic databases for contemporary, peer-reviewed publications that defined and critiqued a clinically utilised informed consent protocol. Two independent researchers conducted multistage filtering, with a third researcher available to resolve conflicts. From the identified articles, clinically utilised risk disclosure tools were identified through a convergent, integrated data extraction process.

Results

1401 unique articles were identified, of which, 20 available articles satisfied the inclusion criteria and passed a quality assessment tool modelled on Joanna Briggs Institute protocols.

Risk disclosure protocols consist of two aspects: the media through which information is presented (e.g., verbal) and the method encompassing how this information is delivered (e.g., absolute statistics). This research considered the suitability of each advocated delivery media and method to disclose ionising radiation risk.

Conclusion

The most advocated protocol to disclose ionising radiation risk involves a complementary approach, using written and verbal communication to deliver contextualised risk information with visual representations, ideally through pictographs.

Implications for practice

The consent model identified in this study stands to improve the quality, accuracy and accessibility of information being disclosed around stochastic risks to better inform patients across person-centred medical imaging contexts.

简介：电离辐射在医学成像中被广泛使用，并有致癌的风险。然而，随机风险的随机性导致电离辐射风险对患者披露不足。这破坏了患者提供的知情同意的有效性，因为不了解随机风险，同意是不知情的。本系统综述旨在通过考虑各个医学领域倡导的知情同意协议的通用性，确定一个理想的协议来披露随机风险，从而为从业者提供一个风险披露框架。方法：本系统综述检索了三个电子数据库，检索当代同行评审的出版物，这些出版物定义和批评了临床使用的知情同意协议。两名独立的研究人员进行多阶段过滤，第三名研究人员可用来解决冲突。从已识别的文章中，通过聚合、集成的数据提取过程确定了临床使用的风险披露工具。结果：鉴定出1401篇独特的文章，其中20篇符合纳入标准，并通过了乔安娜布里格斯研究所方案模型的质量评估工具。风险披露协议包括两个方面：信息呈现的媒介（例如，口头）和包含信息传递方式的方法（例如，绝对统计）。本研究考虑了每一种被提倡的传送媒介和方法是否适合披露电离辐射风险。结论：最受推崇的电离辐射风险披露方案包括一种互补的方法，使用书面和口头交流，以视觉形式传达情境化的风险信息，最好是通过象形文字。实践意义：本研究中确定的同意模型旨在提高随机风险披露信息的质量、准确性和可及性，从而更好地告知以人为中心的医学成像背景下的患者。

Objectives

This review provides methodological guidance, including essential preparatory steps, for conducting systematic literature reviews (SLRs) to produce practical and evidence-based findings that influence the pillars of radiography practice. It also highlights the differences between a scoping review (ScR) and a SLR.

Key findings

SLRs differ from ScRs in their aims, scope, and methodological requirements. SLRs aim to answer specific research questions through comprehensive searches, critical appraisal, and synthesis of empirical studies, while ScRs map the extent of literature on a concept and are more flexible in methodological requirements. Essential components for both include formulation of precise research questions, protocol development, comprehensive literature search, screening and data extraction processes, and evidence synthesis. In addition, a high-quality SLR requires registration of the review protocol and specific qualitative synthesis approaches (e.g., meta-aggregation and meta-synthesis) and/or quantitative synthesis, such as meta-analysis. There are concerns about the lack of a radiography-specific database, necessitating the use of general databases (e.g., PubMed, Scopus, PsycINFO, etc) and discipline-specific sources (e.g., Radiography and related journals). There is also frequent heterogeneity of study designs in radiography research, which can limit the feasibility of meta-analysis in quantitative evidence synthesis.

Conclusion

Both SLRs and ScRs are essential for advancing evidence-based radiography practice. However, researchers need to adhere to established methodological standards to ensure transparency, reproducibility, and relevance of the findings. This will enhance research uptake in clinical practice, education, and policy and inform future research directions.

Implications for practice

Radiography researchers should select review types based on research objectives, apply rigorous and transparent methods, and consider multidisciplinary collaboration to strengthen evidence synthesis. Additionally, training in evidence synthesis methods will improve the rigour and relevance/impact of radiography review articles.

本综述提供了方法学指导，包括必要的准备步骤，用于进行系统文献综述（slr），以产生影响放射学实践支柱的实用和循证发现。它还强调了范围审查（ScR）和单反审查之间的区别。关键发现：sslr与scr在目标、范围和方法要求上有所不同。slr旨在通过综合搜索、批判性评估和综合实证研究来回答特定的研究问题，而scr则映射出一个概念的文献范围，在方法要求上更加灵活。两者的基本组成部分包括制定精确的研究问题、制定方案、全面的文献检索、筛选和数据提取过程以及证据合成。此外，高质量的SLR需要注册审查方案和特定的定性综合方法（例如，元聚合和元综合）和/或定量综合，例如元分析。人们担心缺乏放射学专用数据库，需要使用一般数据库（例如PubMed、Scopus、PsycINFO等）和特定学科来源（例如放射学和相关期刊）。放射学研究的研究设计也经常存在异质性，这限制了meta分析在定量证据合成中的可行性。结论单反和scr对推进循证放射学实践至关重要。然而，研究人员需要遵守既定的方法标准，以确保研究结果的透明度、可重复性和相关性。这将提高临床实践、教育和政策对研究的吸收，并为未来的研究方向提供信息。放射学研究人员应根据研究目标选择综述类型，采用严格和透明的方法，并考虑多学科合作以加强证据综合。此外，证据合成方法方面的培训将提高放射学综述文章的严谨性和相关性/影响力。

Introduction

This article outlines the philosophical and methodological principles and practices of co-production which we employed to co-construct a definition of compassion and conceptual framework of compassionate display.

Methods

Co-production workshops were designed to synthesise and integrate the findings from three different participant cohort focus groups: patients and carers, student therapeutic radiographers and therapeutic radiographers, providing each with a central and equal voice.

Results

A co-produced definition of compassion and conceptual framework were created. The article considers co-production’s role within qualitative research, with a focus on its relationship with participatory inquiry.

Conclusion

We outline the value of co-production across our research and reflect upon its strengths and weaknesses with the ambition to share our learning and provide recommendations for future researchers who wish to utilise this methodological approach for their own qualitative research.

Implications for practice

Co-production can be employed as a methodological approach for research which aims to centralise the patient voice. Researchers should consider and account for the potential costs associated with co-production prior to any applications for funding.

Introduction

Prostate cancer is the most frequently diagnosed male cancer in the Western world, with MRI leading role in detection. The quality of T2-weighted (T2W) sequence can be affected by motion artifacts caused by rectal peristalsis or bladder filling, potentially compromising diagnostic accuracy. Antispasmodics are commonly administered to reduce these artifacts, though their effectiveness remains unclear. This study investigates the impact of antispasmodics and bladder and rectal volumes on motion artifacts in T2W prostate MRI.

Methods

This retrospective study included patients undergoing biparametric MRI (bpMRI) without antispasmodics or multiparametric MRI (mpMRI) with antispasmodics of the prostate. Two observers assessed T2W images using a 3-point Likert scale based on PI-QUAL v2 criteria, focusing on motion artifacts. The Mann–Whitney U test was used to assess differences in Likert scores. Bladder and rectal volumes were analyzed using logistic regression to evaluate their association with Likert scores. Intra- and inter-observer reliability were calculated using Cohen's weighted kappa and Intraclass Correlation Coefficients (ICC).

Results

No significant differences in Likert scores were found between bpMRI and mpMRI groups (p > 0.05). Inter-observer reliability was substantial (k = 0.66), while intra-observer reliability ranged from moderate to almost perfect (k = 0.58 and k = 0.83). Bladder volume was not significantly associated with motion artifacts (p > 0.05), but rectal volumes were (odds ratio 1.023 p = 0.02). Inter-observer reliability was excellent for bladder measurements (ICC = 0.937) and good for rectal measurements (ICC = 0.805).

Conclusion

Administration of glucagon and hyoscine-butylbromide, as well as bladder volume, showed no significant association with motion artifacts on T2W prostate MRI. Larger rectal volume was significantly associated with motion artifacts.

Implications for practice

Routine use of antispasmodics and bladder emptying may be reconsidered in prostate MRI, potentially improving patient comfort and workflow without compromising diagnostic quality.

前列腺癌是西方国家最常见的男性癌症，MRI在诊断中起主导作用。T2W序列的质量可能受到直肠蠕动或膀胱充盈引起的运动伪影的影响，这可能会影响诊断的准确性。抗痉挛药物通常用于减少这些伪影，但其有效性尚不清楚。本研究探讨抗痉挛药和膀胱直肠容积对T2W前列腺MRI运动伪影的影响。方法回顾性研究包括接受双参数MRI （bpMRI）检查无抗痉挛药物或多参数MRI （mpMRI）检查有前列腺抗痉挛药物的患者。两名观察员使用基于PI-QUAL v2标准的3点李克特量表评估T2W图像，重点关注运动伪影。曼-惠特尼U测试用于评估李克特分数的差异。使用逻辑回归分析膀胱和直肠体积以评估其与Likert评分的相关性。使用科恩加权kappa和类内相关系数（ICC）计算观察者内部和观察者之间的信度。结果bpMRI组与mpMRI组的Likert评分差异无统计学意义（p > 0.05）。观察者之间的信度相当高（k = 0.66），而观察者内部的信度从中等到几乎完美（k = 0.58和k = 0.83）。膀胱体积与运动伪影无显著相关性（p > 0.05），但直肠体积与运动伪影有显著相关性（优势比1.023 p = 0.02）。膀胱测量的观察者间信度极佳（ICC = 0.937），直肠测量的观察者间信度良好（ICC = 0.805）。结论T2W前列腺MRI显示，胰高血糖素、海莨菪碱-丁基溴及膀胱体积与运动伪影无显著相关性。较大的直肠容积与运动伪影显著相关。在前列腺MRI中，常规使用抗痉挛药和膀胱排空可能会被重新考虑，可能会改善患者的舒适度和工作流程，而不会影响诊断质量。

Introduction

This study aimed to investigate the prevalence, contributing occupational factors, and consequences of lower back pain (LBP) among diagnostic radiographers in India, a population for whom existing data is sparse. It also assessed associations between ergonomic practices, manual handling, and the career impact of LBP.

Methods

A cross-sectional online survey was distributed to registered diagnostic radiographers across India. The validated questionnaire, covered demographics, LBP history, workload, ergonomic practices, and career impact. Data from 294 respondents were analysed using SPSS v23.0 with descriptive statistics and chi-square tests (p < 0.05).

Results

Nearly half of the participants (47.3 %) reported current LBP, and (50.3 %) had experienced it in the past year. Contributing factors included frequent bending (48.7 %), patient transfers (45.6 %), pushing/pulling equipment (46.3 %), and prolonged use of lead aprons (40.5 %). Although (53.4 %) received manual handling training, (44.6 %) reported transferring patients with inadequate staff, primarily due to time constraints or lack of help. Career impact was notable: (35 %) reported reduced work activity, and (47.3 %) feared long-term effects. Such strain may reduce efficiency, increase fatigue, and impair task performance, affecting patient care.

Conclusion

LBP is highly prevalent among Indian radiographers, linked to ergonomic strain and limited staffing. Compared with global reports (56–75 %), the rates observed in this study are consistent and significantly higher than those of the general population. Targeted ergonomic interventions, realistic training, staffing support, and access to assistive devices are essential to protect radiographers’ health, maintain performance, and support workforce

Implications for practice

Ergonomic interventions, frequent and realistic manual handling training, and better resource allocation are crucial to protect radiographers from LBP. Staffing ratios, mechanical lifting aids, and monitoring systems to evaluate compliance with safe handling practices should also be integrated.

本研究旨在调查印度诊断放射技师中腰痛（LBP）的患病率、影响职业因素和后果，该人群的现有数据很少。它还评估了人体工程学实践、手工操作和腰痛对职业的影响之间的关系。方法对印度注册放射诊断技师进行横断面在线调查。经过验证的问卷调查涵盖了人口统计、LBP历史、工作量、人体工程学实践和职业影响。294名被调查者的数据采用SPSS v23.0进行描述性统计和卡方检验（p < 0.05）。结果近一半的参与者（47.3%）报告目前有LBP， 50.3%的参与者在过去一年中有过LBP。影响因素包括频繁弯曲（48.7%）、患者转移（45.6%）、推/拉设备（46.3%）和长时间使用铅围裙（40.5%）。尽管（53.4%）接受了人工操作培训，（44.6%）报告在人员不足的情况下转移患者，主要是由于时间限制或缺乏帮助。职业影响显著：（35%）报告工作活动减少，（47.3%）担心长期影响。这种紧张可能会降低效率，增加疲劳，损害任务表现，影响病人护理。结论lbp在印度放射技师中非常普遍，与人体工程学压力和人员配备有限有关。与全球报告（56 - 75%）相比，本研究中观察到的发生率是一致的，显著高于一般人群。有针对性的人体工程学干预措施、切实可行的培训、人员支持和辅助设备的使用对于保护放射技师的健康、保持工作表现和支持工作人员至关重要。对实践的影响人体工程学干预措施、频繁和切实可行的人工操作培训以及更好的资源分配对于保护放射技师免受腰痛至关重要。人员配置比例、机械起重辅助设备和监测系统也应加以整合，以评估是否符合安全处理做法。

Survey on the use of patient contact shielding during radiological practice: The European radiographers’ perspective 在放射实践中使用病人接触屏蔽的调查：欧洲放射技师的观点。

IF 2.8 Q2 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING

Introduction

Patient contact shielding (CS) has traditionally been used to protect radiosensitive organs during imaging, however recent European guidelines recommend against its routine use across all X-ray–based modalities, including computed tomography (CT) and interventional radiology (IR), due to advances in technology and updated evidence. Nevertheless, CS continues to be reported in several clinical settings. As radiographers are responsible for applying shielding, this study explores their adherence to current guidelines and the barriers they face in adopting non-shielding practices.

Methods

As part of the EFRS Research Hub at ECR 2024, an anonymous web-based survey was distributed targeting radiographers working in radiography, CT and IR. The questionnaire, delivered via Google Forms, consisted of 20 multiple-choice questions exploring professional practices and attitudes toward patient shielding.

Results

A total of 246 radiographers from 20 European countries participated. While 70.7 % (174/246) reported that their institutions had formally discontinued shielding policies, 39.8 % (98/246) indicated that they still applied shielding in specific circumstances, despite existing departmental policies. Among those continuing its use, 61.2 % (60/98) believed it was effective in reducing unnecessary exposure to radiosensitive organs, and 44.9 % (44/98) felt it provided reassurance to patients and caregivers. Expectations from caregivers (61.2 %; 60/98) and patients (34.7 %; 34/98) were identified as the main barriers to implementation of non-shielding practices. Notably, 73.5 % (72/98) of radiographers reported continued shielding of paediatric patients.

Conclusion

Despite scientific recommendations, CS remains used in clinical practice across Europe. Ongoing efforts are required at both European and national levels to support radiographers through targeted education, communication strategies, and policy alignment, in adherence to guidelines to cease the routine use of shielding.

Implication for practice

There is a need for training, policy alignment and communication strategies to support radiographers in adopting evidence-based non-shielding practices.

患者接触屏蔽（CS）传统上用于成像期间保护放射敏感器官，然而，由于技术的进步和最新证据，最近欧洲指南建议不要在所有基于x射线的模式中常规使用，包括计算机断层扫描（CT）和介入放射学（IR）。然而，CS继续在一些临床环境中被报道。由于放射技师负责应用屏蔽，本研究探讨了他们对现行指南的遵守情况以及他们在采用非屏蔽做法时面临的障碍。方法：作为ECR 2024 EFRS研究中心的一部分，一项匿名的网络调查针对从事放射照相、CT和红外工作的放射技师进行了分发。调查问卷通过谷歌表格进行，包括20个选择题，探讨专业实践和对患者屏蔽的态度。结果：共有来自20个欧洲国家的246名放射技师参与。70.7%（174/246）的受访者表示，他们所在的机构已经正式停止了屏蔽政策，39.8%（98/246）的受访者表示，尽管有现有的部门政策，他们仍然在特定情况下使用屏蔽政策。在继续使用它的人中，61.2%（60/98）认为它有效地减少了对放射敏感器官的不必要暴露，44.9%（44/98）认为它为患者和护理人员提供了保证。来自护理人员（61.2%;60/98）和患者（34.7%;34/98）的期望被认为是实施非屏蔽做法的主要障碍。值得注意的是，73.5%（72/98）的放射技师报告继续屏蔽儿科患者。结论：尽管科学建议，CS仍然在整个欧洲的临床实践中使用。需要在欧洲和国家层面持续努力，通过有针对性的教育、沟通策略和政策协调来支持放射技师，并遵守停止常规使用屏蔽的指导方针。对实践的影响：需要培训、政策协调和沟通策略来支持放射技师采用基于证据的非屏蔽实践。

Introduction

Workforce shortages and rising demand for MRI have increased interest in clinical decision support systems (CDSSs) to standardise imaging workflows. The Prostate Imaging–Reporting and Data System (PI-RADS) committee recommends real-time radiologist input to guide MRI pathways, but workforce constraints may limit consistent implementation. This systematic review examined CDSSs used in prostate MRI, including decision tools, nomograms, and risk calculators, to identify the clinical and MRI-derived variables they incorporate and assess their relevance for future development.

Methods

A systematic search of Medline, Cochrane, CINAHL, Web of Science, and ProQuest was conducted in June 2025. Eligible studies were original research published in English since January 2015 describing development, validation, or clinical use of a CDSS using structured clinical and MRI-derived variables for prostate cancer diagnosis, pre-biopsy risk stratification, or staging. Exclusion criteria included radiomics-only studies, non-primary research, studies without MRI variables, and those lacking external validation. Two reviewers independently screened studies, extracted data, and assessed risk of bias using PROBAST. Certainty of evidence was appraised using the GRADE framework.

Results

Twenty-two studies met inclusion criteria: fifteen evaluated nomograms, five described risk calculators, and two reported predictive models. None assessed a fully implemented CDSS. Common predictors included PI-RADS (82 %), prostate-specific antigen density (64 %), age (64 %), prostate-specific antigen (41 %), and prostate volume (23 %). Most tools showed strong discriminative accuracy (AUC >0.80), though calibration and decision curve analysis were inconsistently reported.

Conclusion

Validated clinical and MRI predictors support robust CDSSs, but heterogeneity and lack of implementation limit evidence. Prospective multicentre validation is needed.

Implications for practice

Radiographer-facing tools integrating key predictors could guide contrast use, staging, and workflow decisions, improve diagnostic accuracy and reduce unnecessary contrast administration.

劳动力短缺和对MRI需求的增加增加了对临床决策支持系统（cdss）的兴趣，以标准化成像工作流程。前列腺成像报告和数据系统（PI-RADS）委员会建议实时放射科医生输入来指导MRI路径，但劳动力限制可能会限制一致性的实施。本系统综述检查了前列腺MRI中使用的cdss，包括决策工具、图和风险计算器，以确定它们所包含的临床和MRI衍生变量，并评估其与未来发展的相关性。方法于2025年6月对Medline、Cochrane、CINAHL、Web of Science、ProQuest进行系统检索。符合条件的研究是2015年1月以来发表的英文原创研究，描述了CDSS的开发、验证或临床应用，使用结构化临床和mri衍生变量进行前列腺癌诊断、活检前风险分层或分期。排除标准包括仅放射组学研究、非初级研究、无MRI变量的研究和缺乏外部验证的研究。两位审稿人独立筛选研究，提取数据，并使用PROBAST评估偏倚风险。使用GRADE框架评估证据的确定性。结果22项研究符合纳入标准：15项研究评估了nomogram， 5项研究描述了risk calculator， 2项研究报告了预测模型。没有评估全面实施的CDSS。常见的预测因素包括PI-RADS（82%）、前列腺特异性抗原密度（64%）、年龄（64%）、前列腺特异性抗原（41%）和前列腺体积（23%）。尽管校准和决策曲线分析的报告不一致，但大多数工具显示出很强的判别精度（AUC >0.80）。结论：经过验证的临床和MRI预测指标支持可靠的cdss，但异质性和缺乏实施限制了证据。需要前瞻性多中心验证。对实际应用的启示面向放射医师的工具集成了关键预测因子，可以指导对比使用、分期和工作流程决策，提高诊断准确性，减少不必要的对比管理。

Introduction

Intravenous cannulation and contrast media (IVCM) administration are diagnostic procedures that enhance the quality of medical imaging examinations. In Zambia, radiologists and nurses traditionally perform IVCM administration due to radiographers' limited scope and lack of specialised training. However, radiographers have begun assisting or performing IVCM administration amid personnel shortages despite limited scope of practice. This study explores Zambian radiographers’ perceptions of expanding their roles to include IVCM administration within diagnostic imaging.

Methods

After ethical approval, a descriptive, phenomenological approach was used to conduct this study. Eight radiographers from two government hospitals in the Lusaka Province were interviewed. Interviews were recorded, transcribed, and analysed thematically using Braun and Clarke's framework to explore the participants' experiences, competencies, and challenges related to IVCM administration.

Results

Four themes were developed: (1)Challenges and concerns related to IVCM administration, (2) Scope of practice for radiographers in Zambia, (3) Role extension and professional development in IVCM administration, and (4) Radiographer training and competence in IVCM administration. Radiographers expressed strong interest in expanding their scope to include IVCM but noted barriers such as inadequate training, limited resources, and safety concerns. They emphasised the need for institutional support and structured training to build competence and confidence.

Conclusion

The findings highlight opportunities to strengthen radiography education, training, and reform policy in Zambia, potentially improving diagnostic imaging and patient outcomes. The insights may benefit other African countries with similar healthcare settings.

Implications for practice

Radiographers’ willingness to extend their roles calls for formal recognition and support for their involvement in IVCM administration. Addressing current barriers could empower radiographers, improve service delivery, and enhance patient safety aligned with international standards.

静脉插管和造影剂（IVCM）给药是提高医学影像学检查质量的诊断程序。在赞比亚，由于放射技师的范围有限和缺乏专业培训，传统上由放射科医生和护士执行IVCM管理。然而，在人员短缺的情况下，尽管实践范围有限，放射技师已经开始协助或执行IVCM管理。本研究探讨了赞比亚放射技师对扩大其角色的看法，将IVCM管理纳入诊断成像。方法经伦理批准后，采用描述性现象学方法进行本研究。采访了卢萨卡省两家政府医院的八名放射技师。使用Braun和Clarke的框架对访谈进行记录、转录和主题分析，以探索参与者与IVCM管理相关的经验、能力和挑战。结果共发展了四个主题：(1)与IVCM管理相关的挑战和关注；(2)赞比亚放射技师的执业范围；(3)IVCM管理中的角色扩展和专业发展；(4)放射技师在IVCM管理方面的培训和能力。放射技师对将其范围扩大到包括IVCM表示了强烈的兴趣，但注意到培训不足、资源有限和安全问题等障碍。他们强调需要体制支助和有组织的培训，以建立能力和信心。结论研究结果强调了加强赞比亚放射学教育、培训和改革政策的机会，有可能改善诊断成像和患者预后。这些见解可能对具有类似医疗保健环境的其他非洲国家有益。对执业放射技师扩展其角色的意愿的影响要求对他们参与IVCM管理的正式认可和支持。解决目前的障碍可以增强放射技师的能力，改善服务提供，并根据国际标准加强患者安全。
