Introduction

Foetal Biometric Parameters (FBP)-based pregnancy dating is vital for monitoring foetal growth. However, the FBP measurements that provide the most reliable gestational age estimations are taken during the first and early second trimesters ultrasound scans, which are often missed in resource-limited settings, necessitating alternatives. This study examined correlations between placental thickness, gestational age, and FBP measurements among pregnant women in the second and third trimesters at Muhima District Hospital and Remera Health Centre in Rwanda.

Methods

A cross-sectional study was conducted on 138 pregnant women with singleton pregnancies dated between 14 and 40 weeks. Placental thickness was measured at the umbilical cord insertion level using ultrasound. Pearson's correlation and linear regression analyses were used to evaluate the relationship between placental thickness, gestational age, and foetal biometric parameters measurements.

Results

A strong positive correlation was observed between placental thickness and gestational age (r = 0.976, p < 0.001). Significant correlations were also noted with biparietal diameter (r = 0.882), p < 0.001; head circumference (r = 0.952), p < 0.001; abdominal circumference (r = 0.967), p < 0.001; and femur length (r = 0.953), p < 0.001. The derived regression equation for gestational age estimation was PT = 0.1 + 1.05 × GA.

Conclusion

Placental thickness strongly correlates with gestational age and foetal biometric parameters, suggesting its potential as a supplementary tool for gestational age estimation. However, longitudinal studies in diverse populations are needed to validate these findings.

Implications for practice

Incorporating placental thickness measurement into routine antenatal ultrasound protocols improves the accuracy of gestational age and delivery date estimation, especially when early scans are missed or the last menstrual period is unknown or unreliable for Naegele's rule-based estimations.

胎儿生物特征参数（FBP）为基础的妊娠日期是监测胎儿生长至关重要。然而，提供最可靠的胎龄估计的FBP测量是在孕早期和孕中期超声扫描期间进行的，这在资源有限的情况下经常被遗漏，因此需要替代方法。本研究调查了卢旺达Muhima地区医院和Remera保健中心妊娠中期和晚期孕妇胎盘厚度、胎龄和FBP测量之间的相关性。方法：对138例14 ~ 40周单胎妊娠妇女进行横断面研究。超声在脐带插入处测量胎盘厚度。使用Pearson相关和线性回归分析来评估胎盘厚度、胎龄和胎儿生物特征参数测量之间的关系。结果：胎盘厚度与胎龄呈正相关（r = 0.976, p < 0.001）。与双顶叶直径也有显著相关性（r = 0.882）， p < 0.001；头围（r = 0.952）， p < 0.001；腹围（r = 0.967）， p < 0.001；股骨长度（r = 0.953）， p < 0.001。所得的胎龄估计回归方程为PT = 0.1 + 1.05 × GA。结论：胎盘厚度与胎龄和胎儿生物特征参数密切相关，可作为胎龄估计的辅助工具。然而，需要在不同人群中进行纵向研究来验证这些发现。实践意义：将胎盘厚度测量纳入常规产前超声方案可提高胎龄和分娩日期估计的准确性，特别是在错过早期扫描或最后一次月经期未知或不可靠的Naegele规则估计时。

Introduction

Informed consent is a legal requirement under The Health and Social Care Act 2008 and a vital part of patient-centred care. Despite national frameworks and guidance, there is significant variability in informed consent implementation across settings. This national service evaluation aimed to assess policies, processes, and principles guiding informed consent for gynaecological radiotherapy across United Kingdom (UK) NHS departments.

Methods

A survey exploring processes and training, principles, and values was sent to 58 NHS radiotherapy departments. Data were obtained from 38 departments (66 % response rate), representing all UK nations. Ethical approval was obtained.

Results

Variation was observed in staff training, use of best-practice guidelines, and content of consent documentation. While 71 % of departments used Royal College of Radiologists (RCR) consent forms, fewer identified professional guidance indicating a potential gap in guideline familiarity. Documentation varied in the number and detail of side-effects described but alignment was observed in core ethical principles. Respondents highlighted structural challenges, notably time and staffing constraints, which limited processes and patient support.

Conclusion

This is the first study to provide a national overview of informed consent policies and practices in NHS radiotherapy departments for gynaecological cancers. It identifies inconsistencies in training, documentation, and guideline awareness, but highlights shared professional values. Findings support the need for national guidance, standardised consent materials, and targeted staff education to ensure equitable and fully informed patient decision-making.

Implications for practice

Informed consent should be treated as an ongoing, patient-centred process that extends beyond the clinician–patient interaction. All staff should be familiar with policies and procedures to support patients’ understanding of treatment and long-term impacts. Standardised materials must be tailored to individual needs to facilitate meaningful, patient-centred discussions.

导言：知情同意是《2008年卫生和社会保健法》的一项法律要求，也是以病人为中心的护理的重要组成部分。尽管有国家框架和指导，但在不同情况下，知情同意的实施存在很大差异。这项国家服务评估旨在评估政策、流程和原则，指导英国（UK） NHS部门对妇科放疗的知情同意。方法：对58个NHS放疗科室进行流程、培训、原则和价值观调查。数据来自38个部门（66%的回复率），代表了所有英国国家。获得伦理批准。结果：在员工培训、最佳实践指南的使用和同意文件的内容方面存在差异。虽然71%的院系使用了皇家放射学院（RCR）的同意书，但较少的院系确定了专业指导，这表明在指南熟悉度方面存在潜在差距。文件中所描述的副作用的数量和细节各不相同，但核心伦理原则一致。受访者强调了结构性挑战，特别是时间和人员配备方面的限制，限制了流程和患者支持。结论：这是第一个研究提供了知情同意政策和实践的国家概述在NHS妇科癌症放疗部门。它确定了培训、文档和指南意识方面的不一致，但强调了共享的专业价值。调查结果支持需要国家指导、标准化的同意材料和有针对性的工作人员教育，以确保公平和充分知情的患者决策。对实践的启示：知情同意应被视为一个持续的，以患者为中心的过程，超出了临床与患者的互动。所有工作人员都应熟悉政策和程序，以支持患者了解治疗和长期影响。标准化的材料必须根据个人需求量身定制，以促进有意义的、以患者为中心的讨论。

Introduction

Magnetic Resonance Imaging (MRI) is the preferred modality for evaluating paediatric brain conditions due to its superior soft tissue contrast and absence of ionising radiation. However, children often require general anaesthesia (GA) to prevent motion artefacts, leading to increased waiting times and costs. The Children-centred Care (CCC) approach reduces the need for GA, but its potential impact on image quality has not been scientifically evaluated.

Methods

This retrospective cohort study included children aged 3–6 years who underwent brain MRI with or without GA in a clinical setting. Three observers performed a Visual Grading Analysis (VGA) to assess image quality on T2-weighted MRIs. The Mann–Whitney U test was used for statistical analysis, and intra- and inter-observer agreement was evaluated using Cohen's and Fleiss' kappa tests.

Results

A total of 70 brain MRIs from 68 children were included, with 22 in the GA group and 48 in the CCC group. Image quality scores were significantly higher in the GA group (mean VGA 4.32 vs. 3.71, p < 0.001). Intra-observer reliability ranged from substantial to perfect (κw = 0.64–0.84), and inter-observer agreement was fair (κ = 0.32). Slice thickness differed slightly with thinnest slices in the GA group (p < 0.001).

Conclusion

T2-weighted paediatric brain MRI under GA showed superior image quality compared to CCC. However, most CCC images were clinically acceptable, suggesting focus on balancing image quality with GA avoidance. Future studies are warranted.

Implications for practice

VGA provides a structured approach to assessing image quality and could form the basis for developing standardised paediatric brain MRI criteria. These findings support CCC as a feasible, patient-centred alternative that reduces anaesthesia use, risks and costs, while enhancing the overall patient experience.

简介：磁共振成像（MRI）是评估儿童脑部状况的首选方式，因为它具有优越的软组织对比和无电离辐射。然而，儿童通常需要全身麻醉（GA）来防止运动伪影，导致等待时间和费用增加。以儿童为中心的护理（CCC）方法减少了对遗传算法的需求，但其对图像质量的潜在影响尚未得到科学评估。方法：这项回顾性队列研究包括3-6岁的儿童，他们在临床环境中接受了有或没有GA的脑MRI。三名观察员进行视觉分级分析（VGA）来评估t2加权核磁共振成像的图像质量。采用Mann-Whitney U检验进行统计分析，采用Cohen’s和Fleiss’s kappa检验评估观察者内部和观察者之间的一致性。结果：共纳入68例儿童70张脑mri，其中GA组22张，CCC组48张。GA组的图像质量评分明显更高（平均VGA为4.32比3.71,p < 0.001）。观察者内部信度范围从相当到完美（κw = 0.64-0.84），观察者之间的一致性为一般（κ = 0.32）。GA组的切片厚度与最薄切片略有差异（p < 0.001）。结论：GA下小儿脑MRI t2加权图像质量优于CCC。然而，大多数CCC图像在临床上是可接受的，这表明应关注图像质量与GA避免的平衡。未来的研究是有必要的。实践意义：VGA提供了一种评估图像质量的结构化方法，可以形成制定标准化儿科脑MRI标准的基础。这些发现支持CCC作为一种可行的、以患者为中心的替代方案，可以减少麻醉的使用、风险和成本，同时增强患者的整体体验。

Introduction

A standardised Medical Imaging Suite (MIS) request form was developed as an educational tool to simulate real-world clinical documentation and improve radiography students’ ability to interpret and communicate medical imaging requests. This form was integrated into the radiography curriculum to support learning outcomes related to clinical reasoning, documentation, and communication. This study evaluates student perceptions of the MIS request form and its influence on their preparedness following their first clinical placement.

Methods

A closed-ended survey was administered to second-year undergraduate (n = 73) and first-year postgraduate (n = 75) diagnostic radiography students at an Australian tertiary institution. The survey captured demographic data; perceived preparedness; communication confidence; usability of the MIS form; and its impact on critical thinking. Quantitative data were analysed descriptively. Optional open-ended questions allowed participants to expand on their responses, and the frequency of each issue was counted and reported as descriptive statistics.

Results

Of 148 eligible students, 137 completed the survey (92.6 % response rate; 48 % undergraduate, 52 % postgraduate). Most respondents were female (78.1 %) and aged 18–25 (84.7 %). Over 75 % agreed that the standardised MIS request form improved their understanding of clinical requests, confidence in interpreting information, and overall preparedness for placement. The redesigned MIS request form was rated clearer and more complete by 84.7 % of students, with 94.5 % recommending its continued use in X-ray practical classes.

Conclusion

Embedding a standardised imaging request form into the radiography curriculum appears to enhance student's clinical preparedness. The form supports the development of critical thinking, documentation accuracy, and interprofessional communication.

Implications for practice

Continued evaluation and refinement of the MIS request form will help maintain strong alignment between university teaching and clinical expectations.

Introduction: Interventional radiology (IR) and interventional cardiology (IC) are rapidly evolving fields in medical imaging that require radiographers with advanced technical and clinical skills. However, education and training for these roles are not yet standardised across Europe. This study examined how undergraduate and postgraduate programmes prepare radiographers for IR and IC roles, with a focus on teaching structure, clinical exposure, graduate competence, and training needs.

Methods: A cross-sectional survey was distributed to radiography academics and clinical educators across Europe using purposive and snowball sampling methods. The online questionnaire comprised 17 items regarding programme duration, ECTS allocation, teaching approaches, clinical placements, and postgraduate study. Descriptive statistics were employed for quantitative data, while open-ended responses were analysed thematically.

Results: Twenty-seven institutions from nine countries participated in the survey. The findings revealed significant variation in programme design (60-240 ECTS) and limited content related to IR and IC. Approximately 44 % (n = 12) of respondents indicated less than 10 h of theoretical instruction, and 37 % (n = 10) provided only 1-2 weeks of clinical exposure, with 11 % (n = 3) offering none. Only 11 % (n = 3) of graduates were perceived as ready for independent practice, while 85 % (n = 23) required supervision. About 74 % (n = 20) reported the absence of postgraduate courses. Competence assessments were primarily conducted in-house, with no national guidelines in place. Identified themes included gaps in pre-registration education, inadequate access to structured training, and minimal utilisation of simulation.

Conclusion: Radiography education in IR and IC across Europe is inconsistent and fragmented hindering graduates' readiness and mobility. European stakeholders should collaborate to develop a harmonised education and competency framework for IR and IC radiographers.

Implications for practice: A harmonised framework will enhance training quality, improve patient safety, and ensure workforce mobility.

简介：介入放射学（IR）和介入心脏病学（IC）是医学成像中快速发展的领域，需要具有先进技术和临床技能的放射技师。然而，针对这些角色的教育和培训尚未在整个欧洲标准化。本研究考察了本科和研究生课程如何使放射技师为IR和IC角色做好准备，重点关注教学结构、临床暴露、研究生能力和培训需求。方法：采用有目的和滚雪球抽样的方法，对欧洲的放射学学者和临床教育工作者进行横断面调查。在线问卷包括17个项目，涉及课程期限、ECTS分配、教学方法、临床实习和研究生学习。定量数据采用描述性统计，而开放式回答则进行主题分析。结果：来自9个国家的27家机构参与了调查。研究结果显示，课程设计存在显著差异（60-240 ECTS），与IR和IC相关的内容有限。大约44% （n = 12）的受访者表示，理论指导时间少于10小时，37% （n = 10）的受访者仅提供1-2周的临床暴露，11% （n = 3）没有提供。只有11% （n = 3）的毕业生被认为准备好独立实践，而85% （n = 23）需要监督。约74% （n = 20）的人报告没有参加研究生课程。能力评估主要在内部进行，没有全国性的指导方针。确定的主题包括注册前教育的差距，获得结构化培训的机会不足以及模拟的最低利用。结论：整个欧洲的IR和IC放射学教育不一致且分散，阻碍了毕业生的准备和流动性。欧洲利益相关者应合作，为红外和集成电路放射技师制定统一的教育和能力框架。对实践的影响：统一的框架将提高培训质量，改善患者安全，并确保劳动力流动性。

Objectives

Artificial intelligence (AI) and machine learning (ML) are increasingly integrated into diagnostic imaging. This review examines how AI adoption affects malpractice risk, the legal standard of care, liability distribution, and informed consent. It also evaluates regulatory developments and ethical concerns, including explicability, autonomy, and professional accountability.

Key findings

AI-supported image interpretation can improve diagnostic accuracy and efficiency. Its integration is reshaping expectations of reasonable clinical practice, with the potential for negligence claims both when clinicians fail to use validated systems and when they rely on insufficiently tested tools. Liability is uncertain because diagnostic responsibility is distributed across clinicians, healthcare organisations, and developers. Existing negligence frameworks assume human reasoning and struggle to accommodate opaque algorithmic decision-making, limiting courts' ability to assess whether AI-assisted diagnoses meet accepted standards. “Black box” models heighten automation bias, hinder legal scrutiny of error, and complicate professional accountability. Informed consent case law suggests AI involvement should be disclosed when it introduces material differences in risk or outcome, although this remains inconsistently applied. Ethical challenges include threats to patient trust, potential clinician deskilling, and reduced transparency in clinical communication. Regulatory initiatives such as the European Union’s General Data Protection Regulation and AI Act move toward clearer governance through requirements for data quality, human oversight, and post-market monitoring, yet explicit malpractice guidance remains under-developed globally.

Conclusion

Traditional legal and ethical frameworks insufficiently address accountability for AI-driven diagnostic errors. Clarifying responsibility, decision authority, and validation requirements is essential to safeguard patient safety and clinician protection.

Implications for practice

Clinical protocols should specify approved use cases, oversight expectations, documentation of AI involvement, and management of clinician-algorithm disagreement. Training should support critical review of outputs to mitigate automation bias.

目的：人工智能（AI）和机器学习（ML）越来越多地集成到诊断成像中。本综述探讨了人工智能的采用如何影响医疗事故风险、法律护理标准、责任分配和知情同意。它还评估监管发展和道德问题，包括可解释性、自主性和专业问责制。主要发现：人工智能支持的图像解译可以提高诊断的准确性和效率。它的整合正在重塑对合理临床实践的期望，当临床医生未能使用经过验证的系统时，以及当他们依赖未经充分测试的工具时，都有可能出现疏忽索赔。责任是不确定的，因为诊断责任分布在临床医生、医疗机构和开发人员之间。现有的过失框架假设人类推理，并努力适应不透明的算法决策，限制了法院评估人工智能辅助诊断是否符合公认标准的能力。“黑匣子”模型加剧了自动化的偏见，阻碍了对错误的法律审查，并使专业问责复杂化。知情同意判例法建议，当人工智能的参与在风险或结果方面带来重大差异时，应予以披露，尽管这一点在适用上仍不一致。伦理挑战包括对患者信任的威胁，潜在的临床医生技能丧失，以及临床沟通透明度降低。欧盟的《通用数据保护条例》和《人工智能法案》等监管举措通过对数据质量、人力监督和上市后监测的要求，朝着更清晰的治理方向发展，但全球范围内明确的不当行为指导仍不完善。结论：传统的法律和伦理框架不足以解决人工智能驱动的诊断错误的问责问题。明确责任、决策权和验证要求对于保障患者安全和临床医生保护至关重要。对实践的影响：临床协议应该指定批准的用例、监督期望、人工智能参与的文档以及临床医生与算法分歧的管理。培训应支持对产出的批判性审查，以减轻自动化偏见。

Introduction

Radiographic quality is the degree to which technical requirements are met that result in clear and accurate reproduction of structures, to enable confident assessment and correct diagnosis. Radiographic image quality therefore comprises technical adequacy and diagnostic utility. It has been suggested that radiographer participation in the image interpretation process may improve their understanding of how these two elements are linked and therefore improve delivery of X-ray quality; however, this has not been directly examined. Therefore, the aim of this study was to investigate radiographers' perspectives on X-ray image quality following the implementation of radiographer commenting.

Methods

Radiographers who worked at hospitals that had implemented a Radiographer Comment and Alert model were invited to participate in one of four online focus groups recorded by Zoom in May–June 2024. The 13 participants, six females and seven males, had between two and 18 years of clinical experience across a range of modalities. Qualitative data was analysed using Braun & Clarke’s Reflexive Thematic Analysis to generate themes and subthemes relevant to the study aim.

Results

Six main themes were identified. The overarching finding was that image interpretation improved understanding and delivery of X-ray quality. The remaining five themes recognised mechanisms contributing to this; increased thought and reflection, enhanced performance expectations radiographers sought to meet, deeper knowledge-building and learning practices, improved technical decision making, and increased collaboration.

Conclusion

Introduction of formal image interpretation practices can be used as a tool to improve radiographers' understanding and production of high-quality X-rays, which provide clinical and economic healthcare benefits.

Implications for practice

Radiographer commenting is within scope for all registered practitioners and can therefore be easily and widely utilised to benefit image quality in the clinical setting.

x线摄影质量是指满足技术要求的程度，从而能够清晰准确地再现结构，从而实现自信的评估和正确的诊断。因此，放射图像质量包括技术充分性和诊断效用。有人建议，放射技师参与图像解释过程可以提高他们对这两个要素如何联系的理解，从而提高x射线的质量；然而，这一点尚未得到直接检验。因此，本研究的目的是探讨在实施放射技师评论后，放射技师对x射线图像质量的看法。方法：邀请在实施放射技师评论和警报模型的医院工作的放射技师参加Zoom于2024年5 - 6月记录的四个在线焦点小组之一。13名参与者，6名女性和7名男性，在一系列模式中有2到18年的临床经验。使用Braun & Clarke的反身性主位分析来分析定性数据，以生成与研究目标相关的主位和副主位。结果：确定了六个主要主题。最重要的发现是图像解释提高了对x射线质量的理解和传递。其余五个主题确认了对此作出贡献的机制；增加了思考和反思，提高了放射技师寻求满足的绩效期望，加深了知识建设和学习实践，改进了技术决策，加强了协作。结论：引入正式的图像解释实践可以作为提高放射技师对高质量x射线的理解和生产的工具，提供临床和经济医疗效益。对实践的影响：放射技师评论在所有注册从业人员的范围内，因此可以很容易和广泛地利用，以提高临床环境中的图像质量。

Introduction

Breast cancer is among the worldwide list of commonly diagnosed cancers and one of the leading causes of highest mortality rate worldwide. Prompt detection facilitates timely and accurate diagnostic investigations required for determining the course of disease and managing it. This meta-analysis aimed to evaluate the sensitivity, specificity, and diagnostic reliability of Axillary Ultrasound (AUS) in detecting axillary lymph node involvement in breast cancer patients.

Methods

On May 17, 2024, a systematic search was performed in PubMed and Embase in accordance with the inclusion criteria of the study. The index test consisted of ultrasonographic diagnostic methods and Fine Needle Aspiration (FNA)-guided Axillary Ultrasound, whereas the reference standard was Sentinel Lymph Node Biopsy (SLNB).

Results

Out of 4874 studies, 19 studies encompassing 9886 patients met the inclusion criteria. The summary sensitivity and specificity of axillary ultrasound were 65.25 % and 87.18 % before outlier adjustment; and 62.20 % and 88.43 % after outlier adjustment respectively. The diagnostic odds ratio (DOR) was 0.27 before outlier and 0.20 after outlier assessment indicating moderate diagnostic performance. Subgroup analysis revealed significant variation in specificity based on risk of bias but not in sensitivity or DOR. The hierarchal Summary receiver operator curve (SROC) demonstrated moderate sensitivity and high specificity in heterogenous studies.

Conclusion

Axillary ultrasound demonstrates high specificity but moderate sensitivity in detecting nodal metastasis in breast cancer. While useful as a preliminary diagnostic tool, it should not replace biopsy-based confirmation. Combining AUS with tissue sampling or advanced imaging may improve preoperative staging accuracy.

Implications for practice

Axillary ultrasound can aid early detection of nodal metastasis but should not replace biopsy confirmation. Integrating AUS with tissue sampling enhances diagnostic accuracy and surgical planning.

简介：乳腺癌是世界范围内常见的癌症之一，也是世界范围内死亡率最高的主要原因之一。及时发现有助于及时和准确的诊断调查，以确定疾病的进程并加以管理。本荟萃分析旨在评估腋窝超声（AUS）检测乳腺癌患者腋窝淋巴结累及的敏感性、特异性和诊断可靠性。方法：于2024年5月17日按照本研究的纳入标准在PubMed和Embase中进行系统检索。指标试验包括超声诊断方法和细针穿刺（FNA）引导下的腋窝超声，参考标准为前哨淋巴结活检（SLNB）。结果：在4874项研究中，19项研究包括9886例患者符合纳入标准。离群校正前腋窝超声的总灵敏度和特异度分别为65.25%和87.18%；经离群值调整后分别为62.20%和88.43%。异常值评估前的诊断优势比（DOR）为0.27，异常值评估后的DOR为0.20，表明诊断效果中等。亚组分析显示，基于偏倚风险的特异性有显著差异，但敏感性或DOR无显著差异。在异质性研究中，分级综合受试者操作曲线（SROC）表现出中等敏感性和高特异性。结论：腋窝超声检查乳腺癌淋巴结转移的特异性高，敏感性中等。虽然作为初步诊断工具有用，但它不应取代基于活检的确认。将AUS与组织取样或高级成像相结合可提高术前分期的准确性。实践意义：腋窝超声可以帮助早期发现淋巴结转移，但不应取代活检确认。将AUS与组织采样相结合可以提高诊断准确性和手术计划。

Introduction

Evaluating patient comfort and acceptance is essential when introducing new imaging technologies. The compact 3T (C3T) MRI system features a unique ergonomic design compared to conventional 60-cm bore whole-body 3T MRI systems (WB3T). This study focuses on comparing the patient experience for brain exams between the C3T and WB3T systems.

Methods

Fifty adult patients undergoing clinically indicated brain MRI exams were imaged using both the C3T and WB3T systems. After completing both scans, participants completed a 12-item questionnaire assessing various aspects of their MRI experience using a 5-point Likert scale. Key areas of evaluation included comfort, noise, vibration, and overall preference.

Results

Survey responses showed that patients reported a more favorable experience with the C3T scanner in several categories, particularly regarding the exam room environment, noise levels, perceived vibrations, and preference for future scans. Both systems were rated as “very desirable” overall, indicating high levels of patient acceptance for each platform.

Conclusion

The compact 3T MRI system offers a patient experience that is comparable to or better than conventional whole-body MRI systems for brain exams. These findings support the integration of the C3T system into clinical practice, especially in environments prioritizing patient comfort and satisfaction.

Implications for practice

By understanding the patient experience on the C3T, it will help to inform future designs and benefits for MRI systems. This study shows that patients find the C3T system comparable or superior to conventional whole-body 3T scanners in comfort, noise, and overall preference. These results suggest the C3T may support improved patient compliance, reduced motion, and greater efficiency in clinical workflows. Findings may also guide MRI manufacturers toward ergonomic, patient-centered innovations in both research and practice.

在引入新的成像技术时，评估患者的舒适度和接受度是必不可少的。与传统的60厘米口径全身3T MRI系统（WB3T）相比，紧凑的3T (C3T) MRI系统具有独特的人体工程学设计。本研究的重点是比较C3T和WB3T系统在脑部检查中的患者体验。方法：使用C3T和WB3T系统对50例接受临床指示的脑MRI检查的成年患者进行成像。在完成两次扫描后，参与者完成了一份12项的问卷，用5分李克特量表评估他们的MRI体验的各个方面。评估的关键领域包括舒适度、噪音、振动和整体偏好。结果：调查结果显示，在几个类别中，患者报告了C3T扫描仪更有利的体验，特别是在检查室环境、噪音水平、感知振动和对未来扫描的偏好方面。这两个系统总体上被评为“非常理想”，表明患者对每个平台的接受程度都很高。结论：紧凑的3T MRI系统为患者提供了与常规全身MRI系统相当或更好的脑部检查体验。这些发现支持将C3T系统整合到临床实践中，特别是在优先考虑患者舒适度和满意度的环境中。实践意义：通过了解患者在C3T上的体验，将有助于为MRI系统的未来设计和效益提供信息。这项研究表明，患者发现C3T系统在舒适度、噪音和总体偏好方面与传统的全身3T扫描仪相当或更好。这些结果表明，C3T可以改善患者的依从性，减少运动，提高临床工作流程的效率。研究结果也可能指导MRI制造商在研究和实践中朝着符合人体工程学、以患者为中心的创新方向发展。

Objectives

Imaging is used in a wide range of contexts in clinical research projects, but adds complexity to the design, conduct and analysis. This paper is the first of two in which we use a consensus approach to bring together multidisciplinary perspectives on the challenges in conducting prospective clinical trials and research studies that include imaging. In this first part we consider challenges in ethics, participant information and consent, recruitment, trial/study and site set-up, training and trial or study conduct.

Key findings

Effective communication with patients regarding the purpose, benefits and risks, and potential future use of imaging data is essential to build trust and support informed participation. Transparency around data handling, including de-identification processes and the right to withdraw consent, underpins ethical research practice. Successful recruitment requires strong collaboration between clinical and imaging teams to ensure clarity, consistency, and efficiency. To reduce participant burden, flexibility should be offered in scheduling and scan requirements, taking into account accessibility and personal commitments. Site setup and staff training benefit from feasibility assessments that evaluate equipment capabilities and identify specific imaging training needs. Clearly defined roles and responsibilities of key personnel support streamlined workflows and accountability. Communication of planned changes to procedures during the study to all stakeholders is key to avoid delays and risks to data integrity. Effective monitoring of procedures, radiation doses (where applicable) and data quality should be pre-planned.

Conclusion

These considerations derived from a multidisciplinary team will be useful for funding applications, protocol design, trial implementation, conduct, commercialisation and uptake of new imaging techniques.

Implications for practice

Many prospective imaging studies could be improved by the upfront awareness of potential challenges and understanding of real-world examples these considerations provide.

目的：影像学在临床研究项目中广泛应用，但增加了设计、实施和分析的复杂性。本文是两篇论文中的第一篇，其中我们使用共识方法将多学科观点结合在一起，讨论进行前瞻性临床试验和包括成像在内的研究的挑战。在第一部分中，我们将考虑伦理、参与者信息和同意、招募、试验/研究和站点设置、培训和试验或研究行为方面的挑战。主要发现：与患者就成像数据的目的、益处和风险以及潜在的未来用途进行有效沟通，对于建立信任和支持知情参与至关重要。数据处理的透明度，包括去识别过程和撤回同意的权利，是伦理研究实践的基础。成功的招募需要临床和成像团队之间的紧密合作，以确保清晰度、一致性和效率。为了减轻参与者的负担，应在日程安排和扫描要求方面提供灵活性，同时考虑到可访问性和个人承诺。现场设置和员工培训受益于评估设备能力和确定特定成像培训需求的可行性评估。明确界定关键人员的角色和职责，支持精简的工作流程和问责制。在研究过程中，与所有利益相关者沟通计划中的程序变更是避免延迟和数据完整性风险的关键。应预先规划对程序、辐射剂量（如适用）和数据质量的有效监测。结论：来自多学科团队的这些考虑将有助于资助应用、方案设计、试验实施、实施、商业化和新成像技术的采用。对实践的启示：许多前瞻性成像研究可以通过预先意识到潜在的挑战和理解这些考虑提供的现实世界的例子来改进。
