Introduction

Artificial Intelligence (AI) is rapidly transforming radiographic practice by improving diagnostic accuracy, enhancing workflow efficiency, and supporting personalised care. Despite this growing relevance, limited research has explored radiography students' perceptions of AI, particularly within Arab academic institutions. This study examines radiography students' knowledge, attitudes, and perceptions of AI in medical imaging to identify educational gaps and guide curriculum development for effective AI integration.

Methods

A multi-national cross-sectional survey of 715 undergraduate radiography students from Egypt, Jordan, and the United Arab Emirates (UAE) was conducted using a validated 45-item questionnaire. Descriptive statistics were applied to assess knowledge, attitudes, and perceived barriers.

Results

Only 27.8 % of participants had attended AI-related training, yet most reported moderate familiarity with AI. Students recognised AI's role in improving diagnostic accuracy and patient outcomes, and 61.8 % supported integrating AI education into undergraduate curricula. Concerns about job replacement were minimal, though barriers included limited access to AI tools, insufficient training, and inadequate expertise among academic staff.

Conclusion

Radiography students demonstrated a positive perception of AI and supported structured education on AI. However, institutional and infrastructural limitations remain.

Impact on practice

These findings underscore the pressing need for structured AI curricula and academic staff training to equip students for evolving clinical roles. Policymakers should prioritize integrating AI education to ensure radiography graduates are ready for AI-enabled healthcare environments.

Introduction

Magnetic Resonance Imaging (MRI) is the most used imaging modality in patients with headaches. However, advanced imaging is often used unwarrantedly, wasting valuable health resources and reducing the quality of care. This study evaluates the outcomes of a national intervention implemented in private imaging centers, assessing differences in profession, referral quality, and justification rate for brain MRI in patients with headaches.

Methods

A before-and-after study was set up to assess referrals retrospectively. Six centers each provided 30 referrals received at the imaging center in January and February 2022, before and 30 referrals after the intervention was implemented (January and February 2023). Four radiographers and four radiologists, all experienced in referral vetting, assessed the referrals using an assessment form, blinded for the year. The chi-square test was used to compare groups (α < 0.05). Kappa statistics were used to assess interrater reliability.

Results

All assessors assessed 353 referrals. Overall, 53 % of referrals were assessed as justified. Interrater agreement was moderate. The rate of justified referrals increased by six percentage points after the intervention. Referral quality increased slightly after the intervention. The interrater agreement was good. Radiologists rated more referrals as high-quality and unjustified compared to radiographers. The interrater agreement in justification assessment was higher among radiologists compared to radiographers.

Conclusions

The intervention increased the rate of justified referrals and decreased the rate of unjustified referrals. However, even after the intervention, 33 % of referrals were rated unjustified, and 57 % were assessed as low-quality. This indicates that referral quality and vetting can be improved.

Implications for practice

To reduce unnecessary brain MRI use, and increase the overall quality of medical imaging, referral quality must be improved, and radiographers need more training in referral vetting.

简介：磁共振成像（MRI）是头痛患者最常用的成像方式。然而，先进的成像常常被毫无根据地使用，浪费了宝贵的卫生资源，降低了护理质量。本研究评估了在私人影像中心实施的国家干预的结果，评估了头痛患者在专业、转诊质量和脑MRI合理化率方面的差异。方法：建立前后对照研究，对转诊患者进行回顾性评估。六个中心分别提供了在干预实施前（2022年1月和2月）和干预实施后（2023年1月和2月）在成像中心收到的30个转诊。四名放射技师及四名放射科医生，均具有审核转介病人的经验，他们使用一份评估表格，对转介病人进行年度的盲法评估。组间比较采用卡方检验（α < 0.05）。采用Kappa统计来评估互译者的信度。结果：所有评估人员对353名转诊患者进行了评估。总体而言，53%的转诊被评估为合理。评价者之间的一致意见是温和的。干预后，合理转诊的比率增加了6个百分点。干预后转诊质量略有提高。翻译协议很好。与放射科医师相比，放射科医师认为更多的转诊是高质量的和不合理的。与放射技师相比，放射科医师在正当性评估中的一致性更高。结论：干预提高了合理转诊率，降低了不合理转诊率。然而，即使在干预之后，33%的转诊被评为不合理，57%被评估为低质量。这表明转介的质量和审查可以得到改善。对实践的启示：为了减少不必要的脑MRI使用，提高医学成像的整体质量，必须提高转诊质量，放射技师需要更多的转诊审查培训。

Introduction

Cone Beam Computed Tomography (CBCT) is essential in Image-Guided Radiation Therapy (IGRT), enabling more accurate treatments but increasing patients exposure to radiation. Despite advancements in dose reduction acquisition methods, routine daily CBCT imaging can still result in a considerable cumulative radiation dose to the patient, which should be considered and assessed.

Methods

This study aimed at estimating the radiation doses absorbed with MOSFET detectors of some radiosensitive organs (e.g. lung, stomach, liver) during thoracic CBCT examination and calculates the risk of cancer incidence and mortality with adult thorax physical phantom.

Results

The absorbed doses in the aforementioned organs ranged between 3 mGy and 8 mGy per fraction, close to the isocenter. Over 33 fractions, the cumulative absorbed dose reached approximately 260 mGy. The analysis of cancer incidence and mortality risk through BEIR VII model revealed that the lungs have the highest number of cases for each age considered (20–80 years interval). Comparing dose assessment obtained using several methods (Monte Carlo, TLDs and MOSFETs), with the same irradiation protocol, lung dose varies among 2.08 mGy and 7.60 mGy, whereas the heart varies among 4.9 Gy and 10 mGy.

Conclusion

Although surrogate dose-index methods are often used, organ absorbed doses assessment should be the preferred method to assess the magnitude of realistic organ radiation risk of populations undergoing examinations with ionizing radiation.

Implications for practice

Promoting experimental dosimetry phantom studies in a more harmonized way would increase the accuracy of organ absorbed dose assessment and consequently would improve the risk communication and decision-making for better CBCT protocols choice in clinical settings.

锥形束计算机断层扫描（CBCT）在图像引导放射治疗（IGRT）中是必不可少的，它使治疗更准确，但增加了患者的辐射暴露。尽管剂量减少获取方法取得了进步，但常规的每日CBCT成像仍然会给患者带来相当大的累积辐射剂量，这应该被考虑和评估。方法：本研究旨在估计胸部CBCT检查中某些放射敏感器官（如肺、胃、肝）的MOSFET探测器吸收的辐射剂量，并计算成人胸腔物理幻象的癌症发病率和死亡率风险。结果：上述器官的吸收剂量范围为3 ~ 8mgy /份，接近等中心。在33个组分中，累积吸收剂量达到约260 mGy。通过BEIR VII模型对癌症发病率和死亡风险的分析显示，在每个考虑的年龄（20-80岁间隔）中，肺部的病例数最多。比较使用几种方法（蒙特卡罗、TLDs和mosfet）获得的剂量评估，在相同的辐照方案下，肺部剂量在2.08和7.60 mGy之间变化，而心脏剂量在4.9和10 mGy之间变化。结论：虽然经常使用替代剂量指数法，但器官吸收剂量评估应是评估接受电离辐射检查人群实际器官辐射风险大小的首选方法。实践意义：以更统一的方式促进实验性剂量学幻象研究将提高器官吸收剂量评估的准确性，从而改善临床环境中更好的CBCT方案选择的风险沟通和决策。

Introduction

In the era of personalised medicine, tumour hypoxia (TH) is critical in radiotherapy (RT) response due to its role in tumour resistance. Positron Emission Tomography (PET) enables non-invasive assessment of TH and supports heterogeneous dose-escalation to hypoxic sub-volumes, improving treatment efficacy. This study explores Nuclear Medicine Technologists (NMT) and Radiotherapy Technologists (RTT) perceptions of PET-based TH (PET-TH) assessment and implementation in RT planning in Portugal.

Methods

We conducted an observational cross-sectional survey of RTTs and NMTs currently working in Portuguese healthcare institutions. Statistical tests were used to assess associations and compare distributions using IBM® SPSS®.

Results and discussion

A total of 66 participants, 57 (86.4 %) females, with a mean age of 33.68 (±8.13) years, were included: 23 (34.8 %) NMTs and 43 (65.2 %) RTTs. While 65.2 % of NMT departments had PET scans with RT-compatible settings, only 8.7 % had performed PET-TH studies. Among RTTs, 88.4 % reported that their treatment planning systems were compatible with PET/CT fusion, yet only 9.3 % had used PET in RT planning. RTTs received more training in TH (p = 0.006) and rated their knowledge higher than NMTs (p = 0.042). Greater professional experience and higher perceived knowledge were associated with better performance on evaluation items (p = 0.027; p = 0.037). Regardless of institution type, 92.4 % expressed interest in interprofessional collaboration to support individualised planning.

Conclusion

The assessed departments possess infrastructures for PET-TH integration, yet clinical implementation remains limited. Knowledge and professional experience are associated with competency. Targeted training for Technologists and interdisciplinary workflows may improve PET-TH adoption.

Implications for practice

Addressing knowledge and workflow could facilitate PET integration into RT planning and potentially enhance treatment outcomes. Future efforts should focus on interdisciplinary collaboration.

在个体化医疗时代，肿瘤缺氧（TH）由于其在肿瘤抵抗中的作用而在放疗（RT）反应中起着至关重要的作用。正电子发射断层扫描（PET）可以对TH进行无创评估，并支持异质性剂量递增到缺氧亚容量，提高治疗效果。本研究探讨了核医学技术人员（NMT）和放射治疗技术人员（RTT）对葡萄牙RT计划中基于pet的TH （PET-TH）评估和实施的看法。方法：我们对目前在葡萄牙医疗机构工作的rtt和nmt进行了一项观察性横断面调查。使用IBM®SPSS®进行统计检验以评估相关性并比较分布。结果与讨论共纳入66例受试者，女性57例（86.4%），平均年龄33.68（±8.13）岁，其中nmt患者23例（34.8%），rtt患者43例（65.2%）。而65.2%的NMT科室进行了rt兼容设置的PET扫描，只有8.7%进行了PET- th研究。在rtt中，88.4%的人报告他们的治疗计划系统与PET/CT融合兼容，但只有9.3%的人在RT计划中使用PET。rtt接受了更多的TH培训（p = 0.006），对其知识的评价高于nmt （p = 0.042）。较高的专业经验和较高的认知知识与较好的评估项目绩效相关（p = 0.027; p = 0.037）。无论机构类型如何，92.4%的受访者表示对跨专业合作以支持个性化规划感兴趣。结论被评估科室具备PET-TH整合的基础设施，但临床实施仍有限。知识和专业经验与能力相联系。针对技术人员和跨学科工作流程的有针对性的培训可能会提高PET-TH的采用。解决知识和工作流程可以促进PET整合到RT计划中，并有可能提高治疗效果。未来的努力应侧重于跨学科合作。

Introduction

The challenges in providing quality practice place learning in pre-registration diagnostic radiography education has seen a rising interest in the use of simulation-based education (SBE) within the UK and other countries. This study aimed to determine the current use and efficacy of SBE across UK higher education institutions.

Methods

An online survey was distributed to educators delivering pre-registration diagnostic radiography programmes within the UK via professional networks and social media in 2024.

Results

18 respondents reported use of SBE within programmes to support a range of areas within the curriculum, develop skills and prepare students for placement. Reported usage ranged from between ≥50 h and 301–350 h. Staff capacity (61.1 %) and cost of equipment (55.5 %) were highlighted as the biggest challenges to delivering SBE. The majority of respondents use pre-brief (66.6 %) and debriefs (27.7 %) or feedback (50.0 %) as part of SBE. Live radiographic imaging equipment (94.4 %) and roleplay (83.3 %) were most frequently used. Methods of evaluating the learning gain include anecdotal evidence, student self-reporting and assessment results, with increased confidence most frequently cited as the impact of SBE.

Conclusion

Despite the challenges, SBE is a widely used and accepted pedagogy in pre-registration diagnostic radiography education.

Implications for practice

Ongoing faculty training and adherence to simulation standards is important to ensure SBE provides a quality learning experience. There is an opportunity to embed more robust mechanisms for evaluating the learning gain associated with SBE.

在注册前诊断放射学教育中提供高质量实践场所学习的挑战，在英国和其他国家，人们对使用基于模拟的教育（SBE）越来越感兴趣。本研究旨在确定当前在英国高等教育机构中SBE的使用和有效性。方法于2024年通过专业网络和社交媒体向英国境内提供预注册放射诊断课程的教育工作者分发了一份在线调查。结果18名受访者报告了在课程中使用SBE来支持课程中的一系列领域，培养技能并为学生的安置做好准备。报告的使用时间从≥50小时到301-350小时不等。人员能力（61.1%）和设备成本（55.5%）是交付SBE的最大挑战。大多数受访者使用预简报（66.6%）和汇报（27.7%）或反馈（50.0%）作为SBE的一部分。现场放射成像设备（94.4%）和角色扮演（83.3%）是最常用的。评估学习收获的方法包括轶事证据、学生自我报告和评估结果，其中最常被引用的是SBE的影响，即增加了信心。结论尽管面临诸多挑战，SBE教学法在预注册诊断放射学教育中仍被广泛采用和接受。对实践的启示持续的教师培训和遵守模拟标准对于确保SBE提供高质量的学习体验非常重要。有机会嵌入更健壮的机制来评估与SBE相关的学习收益。

Introduction: CT-guided percutaneous lung biopsy remains essential for diagnosing pulmonary nodules but is frequently complicated by pneumothorax, hemorrhage, and hemoptysis. Laser-assisted CT-guided biopsy (LACT) has been proposed to enhance procedural precision and safety. This meta-analysis compared the efficacy and safety of LACT versus conventional CT-guided (CCT) lung biopsies.

Methods: A comprehensive search of six electronic databases was performed to identify studies comparing LACT and CCT lung biopsies. Statistical analyses were performed using RevMan 5.4.1, and P < 0.05 was considered statistically significant. Meta-regression was done by Open Meta-Analyst.

Results: Twelve studies involving 1353 patients were included. The LACT group demonstrated significantly higher first-puncture success (RR = 2.47, 95 % CI: 1.44-4.23, P = 00.001), fewer CT scans and needle adjustments (MD = -1.50, 95 % CI: -2.08 to -0.91, P < 0.00001), shorter procedure duration (MD = -7.69 min, 95 % CI: -9.75 to -5.64, P < 0.00001), and shorter intraoperative time (P < 0.00001). LACT also showed a lower overall complication rate, including pneumothorax, hemorrhage, and hemoptysis. Meta-regression indicated that increasing age was associated with a higher pneumothorax risk.

Conclusions: LACT-guided lung biopsy improves first-puncture success, procedural efficiency, and safety compared with the conventional approach. However, as most studies originated from a single geographic region and had variable methodological quality, these findings require confirmation through larger, multicenter randomized controlled trials.

Implications for practice: LACT may offer procedural and safety advantages over conventional CT-guided lung biopsy, with the potential to reduce risks to patients. Future considerations include the need for robust, generalizable evidence beyond the studied population and geographic setting, along with support for wider clinical implementation such as standardized device specifications, workflow and protocol optimization, professional-body guidance, and operator training.

简介：ct引导下的经皮肺活检对于诊断肺结节仍然是必不可少的，但经常并发气胸、出血和咯血。激光辅助ct引导活检（LACT）已被提出，以提高程序的准确性和安全性。这项荟萃分析比较了LACT与传统ct引导（CCT）肺活检的疗效和安全性。方法：对六个电子数据库进行全面检索，以确定比较LACT和CCT肺活检的研究。采用RevMan 5.4.1软件进行统计学分析，P < 0.05为差异有统计学意义。元回归是由Open Meta-Analyst完成的。结果：纳入12项研究，共1353例患者。LACT组首次穿刺成功率较高（RR = 2.47, 95% CI: 1.44 ~ 4.23, P = 0.00001）， CT扫描和调针次数较少（MD = -1.50, 95% CI: -2.08 ~ -0.91, P < 0.00001），手术时间较短（MD = -7.69 min, 95% CI: -9.75 ~ -5.64, P < 0.00001），术中时间较短（P < 0.00001）。LACT也显示出较低的并发症发生率，包括气胸、出血和咯血。meta回归显示，年龄的增加与气胸风险的增加有关。结论：与传统方法相比，lact引导下的肺活检提高了首次穿刺成功率、手术效率和安全性。然而，由于大多数研究来自单一地理区域，方法质量参差不齐，这些发现需要通过更大规模的多中心随机对照试验来证实。实践意义：与传统ct引导下的肺活检相比，LACT可能具有程序性和安全性方面的优势，有可能降低患者的风险。未来的考虑包括需要在研究人群和地理环境之外提供可靠的、可推广的证据，以及支持更广泛的临床实施，如标准化设备规格、工作流程和方案优化、专业机构指导和操作人员培训。

Introduction

Portable imaging in Neonatal Intensive Care Unit (NICU) is challenging due to lack of standardized protocols resulting in repeated exposures and inconsistent image quality. This study aims to explore the lived experiences of interprofessional collaboration (IPC) with implementing a standardized portable imaging protocol (SPIP) in NICU and assess its perceived impact on workflow and safety and image quality.

Methods

A purposive sampling was used to recruit participants, including radiographers, nurses, respiratory therapists, and radiologists. Semi-structured interviews were conducted, and thematic analysis was used to analyse data. Quantitative data was collected using evaluation of image quality to provide measurable trends.

Results

The thematic analysis revealed five main themes: HCPs' role before SPIP, HCPs' role after SPIP, perceived impact of IPC on patient care, safety, and radiation protection, HCPs' perception, and sustainability of SPIP. Prior to the implementation, roles were unclear, communication was minimal, and workflow inefficiencies frequently led to suboptimal image quality and repeated exposures. Following the implementation, HCPs reported enhanced efficiency, clearer role definition, better communication, and improved radiation safety. By the third month, correct positioning rose from 13 % to 68 %, proper inspiration improved from 62 % to 97 %, and suboptimal images dropped from 87 % to 31 %.

Conclusion

HCPs reported improvements in workflow efficiency, communication, and adherence to radiation safety, and image quality through role clarity and teamwork. Their experiences suggest that IPC may contribute to optimizing imaging outcomes in the NICU.

Implications for practice

Structured feedback mechanisms are recommended to foster continuous learning, supported with ongoing training, audits, and protocol updates based aligned with best practices. Further research is needed to evaluate the protocol's effectiveness, scalability, and adaptability across diverse settings.

新生儿重症监护病房（NICU）的便携式成像具有挑战性，因为缺乏标准化的协议，导致重复曝光和图像质量不一致。本研究旨在探讨在NICU实施标准化便携式成像协议（SPIP）的跨专业协作（IPC）的生活经验，并评估其对工作流程、安全和图像质量的感知影响。方法采用有目的的抽样方法，招募包括放射技师、护士、呼吸治疗师和放射科医师在内的参与者。采用半结构化访谈，并采用专题分析对数据进行分析。定量数据收集使用评价图像质量，以提供可测量的趋势。结果主题分析揭示了五个主要主题：SPIP前HCPs的作用、SPIP后HCPs的作用、IPC对患者护理、安全和辐射防护的感知影响、HCPs的感知和SPIP的可持续性。在实现之前，角色不明确，沟通很少，工作流程效率低下经常导致图像质量不理想和重复曝光。实施后，HCPs报告效率提高，角色定义更清晰，沟通更好，辐射安全性得到改善。到第三个月，正确的定位从13%上升到68%，适当的灵感从62%提高到97%，不理想的图像从87%下降到31%。结论通过角色清晰和团队合作，hcps报告了工作流程效率、沟通、对辐射安全的依从性和图像质量的改善。他们的经验表明，IPC可能有助于优化新生儿重症监护室的成像结果。对实践的启示建议采用结构化的反馈机制来促进持续学习，并支持持续的培训、审核和基于最佳实践的协议更新。需要进一步的研究来评估协议的有效性、可扩展性和跨不同设置的适应性。

Introduction

Mistakes are part of ultrasound practice, but the emotional impact of mistakes on sonographers remains poorly understood. This study explored the emotional consequences of mistakes among UK sonographers and identified strategies to mitigate their effects.

Methods

A cross-sectional online survey was conducted in the UK from December 2024 to February 2025. Fifty-three sonographers were recruited through professional networks and member platforms. The survey, hosted on the JISC platform, included quantitative items and open-ended questions. Quantitative data were analysed using descriptive statistics and non-parametric tests in SPSS 28, while qualitative data were coded thematically using Braun and Clarke's framework in NVivo 12.

Results

Thirty-nine respondents reported at least one diagnostic-type error at some point in the past year. Mistakes occurred across all settings (p = 0.107) and experience levels (p = 0.624). Guilt (45.3 %), shame (25 %), and perceptions of scapegoating (33.3 %) were common. Most participants (69 %) reported receiving emotional support after making mistakes (N = 52; no response = 1). Coping strategies varied, though none were significantly associated with setting or experience (p > 0.05). Four themes emerged from qualitative analysis: workplace culture and interpersonal dynamics, emotional and psychological impact, reporting and learning from Mistakes, and recommended support and mitigation strategies.

Conclusion

Diagnostic mistakes are common and emotionally challenging for sonographers. Existing institutional responses are perceived as insufficient. A just culture that prioritises psychological safety, non-punitive reporting, prompt debriefing, and access to counselling supports staff wellbeing, retention, and patient safety.

Implications for practice

Organisations must move beyond policy statements and provide confidential, non-punitive reporting pathways, easily accessible psychological support, and managers trained in empathetic communication to ensure responses to mistakes prioritise learning rather than fault.

错误是超声实践的一部分，但错误对超声医师的情感影响仍然知之甚少。这项研究探讨了英国超声检查人员错误的情感后果，并确定了减轻其影响的策略。方法于2024年12月至2025年2月在英国进行横断面在线调查。通过专业网络和会员平台招募53名超声技师。该调查由JISC平台主持，包括定量项目和开放式问题。定量数据在SPSS 28中使用描述性统计和非参数检验进行分析，而定性数据在NVivo 12中使用Braun和Clarke的框架进行主题编码。结果39名受访者在过去一年中至少报告了一次诊断类型错误。错误发生在所有设置（p = 0.107）和经验水平（p = 0.624）。内疚（45.3%）、羞耻（25%）和找替罪羊的感觉（33.3%）是常见的。大多数参与者（69%）报告在犯错后得到了情感支持（N = 52；无回应= 1）。应对策略各不相同，但没有一个与环境或经历显著相关（p > 0.05）。定性分析产生了四个主题：工作场所文化和人际关系动态、情绪和心理影响、报告和从错误中吸取教训，以及建议的支持和缓解战略。结论超声诊断错误是常见的，也是对超声医师情感上的挑战。现有的机构反应被认为是不够的。一种公正的文化，优先考虑心理安全、非惩罚性报告、及时汇报和获得咨询，有助于员工的福祉、留任和患者安全。对实践的启示组织必须超越政策声明，提供保密的、非惩罚性的报告途径，容易获得的心理支持，以及受过移情沟通培训的管理者，以确保对错误的反应优先考虑学习而不是错误。

Introduction

Photon-counting detector CT (PCD-CT) offers superior spatial resolution and noise characteristics compared to conventional CT. However, optimal reconstruction parameters for temporal bone imaging, especially kernel selection, remain unclear. This study aimed to identify the optimal reconstruction kernel using both objective physical image quality metrics and subjective expert assessments.

Methods

In phantom experiments, the system performance function (SPF) based on the task-based transfer function (TTF) and noise power spectrum (NPS) was calculated across 11 reconstruction kernels (Hr60–Hr98). Based on the results of the physical evaluation and clinical considerations from clinical practice, a subset of kernels was selected for visual assessment. For clinical images, two diagnostic radiologists evaluated three fine anatomical structures (i.e., stapes footplate, incudomalleolar joint, and cochlea) and overall image quality using both a ranking method and a 5-point Likert scale.

Results

TTF analysis indicated that Hr96 had the highest spatial resolution, while Hr60 showed the lowest noise in the NPS. SPF analysis identified Hr72 as providing the optimal balance between resolution and noise. Visual assessment using four reconstruction kernels (Hr60, Hr72, Hr76, and Hr84) showed that Hr76 consistently received the highest preference for overall image quality and visualization of fine structures. Statistically significant differences were observed among the kernels, with Hr60 consistently rated the lowest (p < 0.05).

Conclusion

The kernel Hr76 was found suitable for middle and inner ear diagnoses using PCD-CT, providing a good balance between spatial resolution and image noise. This finding provides a foundation for standardized reconstruction protocols in high-resolution temporal bone imaging.

Implications for practice

These findings support the use of Hr76 as a standard kernel for high-resolution temporal bone imaging and may contribute to protocol optimization in clinical PCD-CT practice.

与传统CT相比，光子计数检测器CT （PCD-CT）具有更好的空间分辨率和噪声特性。然而，颞骨成像的最佳重建参数，特别是核选择，仍不清楚。本研究旨在利用客观的物理图像质量指标和主观的专家评估来确定最佳的重建核。方法在模拟实验中，计算基于任务传递函数（TTF）和噪声功率谱（NPS）的11个重构核（hr60 ~ hr98）的系统性能函数（SPF）。根据物理评估结果和临床实践的临床考虑，选择核子集进行视觉评估。对于临床图像，两名诊断放射科医师使用排名法和5分李克特量表评估了三个精细解剖结构（即镫骨、足板、包括踝关节和耳蜗）和整体图像质量。结果sttf分析表明，在NPS中，Hr96的空间分辨率最高，Hr60的噪声最低。SPF分析确定Hr72在分辨率和噪声之间提供了最佳平衡。采用Hr60、Hr72、Hr76和Hr84四个重建核进行视觉评价，结果显示Hr76在整体图像质量和精细结构可视化方面始终获得最高的偏好。不同籽粒间差异有统计学意义，Hr60始终被评为最低（p < 0.05）。结论Hr76核磁共振成像在空间分辨率和图像噪声之间取得了很好的平衡，适用于PCD-CT中耳和内耳诊断。这一发现为高分辨率颞骨成像的标准化重建方案提供了基础。这些发现支持使用Hr76作为高分辨率颞骨成像的标准内核，并可能有助于临床PCD-CT实践的方案优化。

Introduction

Pelvic radiography is common technique for investigating hip pain, pre-operative planning and in post-surgical surveillance. Variations in anteroposterior (AP) radiographic technique have been described in the literature and are in routine practice. The aim of this study was to compare a single standardised technique (Intervention-Site 1) against individual radiographer determined techniques (Control-Site 2).

Methods

The study was prospective in design and recruited adult ambulant patients referred for pelvic radiography. Site 1 ‘Intervention’ used a single standardised AP technique and Site 2 ‘Control’ allowed radiographers to determine their own optimum technique. Comparisons between the study sites included radiation dose, image quality and repeat rates. It was hypothesised that Site 1 would have lower radiation doses and fewer repeats. Demographics including sex, age and BMI were collected to ensure comparability between sites.

Results

292 patients were recruited 161 (55 %) from Site 1 and 131 (45 %) Site 2. There were no statistically significant differences in terms of male to female ratio, age and BMI (p > 0.05). Median (IQR) DAP values were insignificantly lower at Site 2 11.4 (7.9–14.3) dGy.cm² when compared to Site 1 12.9 (8.2–18.6) dGy.cm² (p = 0.07). Repeat rates were marginally higher at Site 1 (24 %) when compared to Site 2 (19 %), but not statistically significant (p = 0.291). The missing of anatomical structures was statistically less frequent at Site 1 (12 %) when compared to Site 2 (24 %) (p = 0.009).

Conclusion

Initial evaluation of study data suggests that radiation doses and repeat rates were comparable. Opting for a standardised technique may yield more technically ‘perfect’ radiographs.

Implications for practice

Outside of radiation dose and repeat rates a standardised pelvic X-ray technique may yield improvements in technical completeness and image quality.

骨盆x线摄影是调查髋关节疼痛、术前计划和术后监测的常用技术。正位（AP） x线摄影技术的变化已经在文献和常规实践中被描述。本研究的目的是比较单一的标准化技术（interintersite - 1）和单独的放射技师确定的技术（Control-Site - 2）。方法本研究采用前瞻性设计，招募转诊骨盆x线摄影的成年门诊患者。Site 1“干预”使用单一标准化AP技术，Site 2“控制”允许放射技师确定自己的最佳技术。研究地点之间的比较包括辐射剂量、图像质量和重复率。据推测，一号站点的辐射剂量较低，重复次数较少。收集了包括性别、年龄和BMI在内的人口统计数据，以确保不同地点之间的可比性。结果292例患者入组，161例（55%）来自1区，131例（45%）来自2区。男女比例、年龄、BMI差异均无统计学意义（p > 0.05）。中位（IQR） DAP值在Site 2的11.4 (7.9-14.3)dgg处无显著性降低。与Site 1 12.9（8.2-18.6）平方英尺相比。Cm2 （p = 0.07）。重复率在第1区（24%）略高于第2区（19%），但无统计学意义（p = 0.291）。1号位点解剖结构缺失的发生率（12%）低于2号位点（24%）（p = 0.009）。结论对研究资料的初步评价表明，辐射剂量和重复率具有可比性。选择标准化的技术可能会产生技术上更“完美”的x光片。实践意义除了辐射剂量和重复率外，标准化骨盆x线技术可以提高技术完整性和图像质量。
