Image interpretation by radiographers has gained widespread recognition; however, current evidence provides very limited knowledge of the state and scope of practice transnationally. This study therefore sought to explore the current state and scope of preliminary clinical evaluation (PCE) practice to further understand international best practices in terms of policy, training and education, and practice competence of radiographers when carrying out PCE.
Method
A comprehensive literature search was completed via federated electronic databases (EBSCOhost and Web of Science) and professional radiography platforms for journal articles and policy or practice guidance documents, respectively. Data were charted from eligible studies following screening of articles in accordance with the predefined eligibility criteria. Themes were generated using inductive narrative analysis.
Results
Thirty-one peer reviewed articles and 5 radiography practice policy documents were identified. Over 60% of the included studies were carried out in the United Kingdom and Australia with about 60% focused on projectional radiography of the appendicular and axial skeletons. Three main themes were developed and included: scope of PCE practice and implementation; PCE proficiency indicators; factors influencing PCE participation and performance.
Conclusion
Gaps exist around defined scope of practice, standardisation, commenting format and compliance with policy. There is very limited evidence around PCE practice in cross-sectional imaging, thus, it is difficult to ascertain the current state and scope of practice internationally. There is a need for countries to develop standard commenting frameworks as well as enforcement of compliance. Additionally, more research is required to ascertain the competence and benefits of PCE practice within cross sectional imaging.
导读：放射技师的图像解译得到了广泛的认可；然而，目前的证据提供的跨国实践的状态和范围的知识非常有限。因此，本研究旨在探讨初步临床评估（PCE）实践的现状和范围，以进一步了解国际上在政策、培训和教育方面的最佳做法，以及放射技师在实施PCE时的实践能力。通过联邦电子数据库（EBSCOhost和Web of Science）和专业放射学平台分别完成了期刊文章和政策或实践指导文件的全面文献检索。数据从符合条件的研究中绘制图表，根据预先确定的资格标准对文章进行筛选。主题是通过归纳叙事分析产生的。结果：确定了31篇同行评议文章和5份放射学实践政策文件。超过60%的纳入研究是在英国和澳大利亚进行的，其中约60%的研究集中在阑尾和轴向骨骼的投影x线摄影上。制定并包括三个主要主题：个人教育实践和实施的范围；PCE熟练度指标；影响PCE参与和绩效的因素。结论：在界定实践范围、标准化、评议格式和政策遵从性方面存在差距。关于断层成像中PCE实践的证据非常有限，因此很难确定国际上的实践现状和范围。各国有必要制定标准的评论框架以及执行合规。此外，需要更多的研究来确定PCE在横断面成像中的能力和益处。

Aims
This scoping review aimed to (1) map the global evidence on extended and advanced clinical practices (ACP) performed by radiographers, and (2) provide an overview of the pillars (clinical practice, leadership and management, education, and research) they relate to, as well as the radiology areas and the geographical location where they were developed.
Methods
Articles were searched in MEDLINE, CINAHL and Embase, and grey literature in ProQuest Dissertation and Theses. Studies concerning radiographers or healthcare professionals with an equivalent title (e.g., radiation technologist) performing extended role or an ACP, regardless of their medical imaging setting or country were included. The review was undertaken following JBI methodological guidance for scoping reviews. The titles and abstracts of the retrieved studies, and then the full texts of the selected papers were assessed by two independent reviewers.
Results
A total of 2617 records were identified, of which 174 articles were included. Most of them reported practices performed in the UK (63 %), and less in Canada (19 %) and Australia (6 %). Advanced or extended practices were linked to all four pillars, but most concerned the clinical practice pillar. The main activities for this pillar were radiograph reporting (22 %), patient assessment and management (consultation) in radiotherapy (RT; 21 %), RT treatment planning (14 %) and ultrasound practice (13 %). Studies have also shown radiographers performing breast biopsies, medication prescription, and ultrasound and CT scan reports. The main fields of radiology concerned by the changing roles were radiotherapy (42 %) and conventional radiography (36 %).
Conclusion
Extended or advanced practices are achieved through a wide variety of activities around the world. This scoping review constitutes a knowledge base on the evolution of the practices of radiographers and should contribute to their recognition and development.

Resolution 60.29 (18) of the 60th United Nations World Health Assembly urges member states to gather, verify, update, and exchange information on health technologies, especially medical devices. This study assesses Zimbabwe's MRI service availability and cost, identifies disparities, and discusses implications for patient care and healthcare equity, proposing evidence-based improvement strategies.
Methods
A cross-sectional survey was conducted to capture the specifications of all the MRI equipment, including manufacturer, type of magnet, magnetic field strength, location, and installation year. Data obtained was analyzed using the Stata 13.
Results
As of 27 April 2024, there were 11 MRI scanner units in Zimbabwe, 9 of the MRI machines were operational, while 2 were not operational. The majority of these scanners (8 [73 %]) are located in the private health sector. All the units are situated in urban provinces. Out of the 11 units, 7 (64 %) are located in the Harare Metropolitan Province, 3 (27 %) are in the Bulawayo Metropolitan Province, and 1 (9 %) is in the Midlands Province. All MRI examinations, except for head scans, were more expensive in the private sector compared to the public sector.
Conclusions
The survey on MRI equipment availability and utilization in Zimbabwe revealed major differences in access to this critical diagnostic tool. Strategies for improvement include targeted investments in MRI units, funding programs for healthcare providers, equipment-sharing initiatives, subsidy programs, standardized protocols, and strategic collaborations between Original Equipment Manufacturers and the government.

Background
Clear communication during informed consent is crucial in paediatric computed tomography (CT) procedures, particularly in resource-constrained settings. CT offers valuable diagnostic information but carries potential radiation risks, especially for paediatric patients. Parents play a critical role in decision-making, necessitating thorough risk-benefit discussions. This study aimed to explore parental experiences regarding risk-benefit communication during their children's CT scans in under-resourced healthcare facilities.
Methods
A qualitative approach with a descriptive design was employed. Semi-structured interviews were conducted with 13 purposefully selected and consenting parents accompanying paediatric patients for CT scans at two public hospitals. Data were analysed using Tesch's eight-step method and ATLAS.ti software.
Results
Participants were parents of children aged 0–10 years (8 males, 5 females), with 11 making their first visit to the CT department. Three main themes emerged: (1) Compromised consenting process, characterised by inadequate explanation of consent and limited risk-benefit communication; (2) Procedural information deficiency, including minimal communication about the procedure and lack of information on examination results; and (3) Preference for improved communication, with parents expressing a desire for comprehensive information and varied opinions on who should disseminate this information. Parents reported feeling uninformed, anxious, and unable to make well-informed decisions due to communication gaps.
Conclusions
Significant improvements are needed in risk-benefit communication during paediatric CT scans. Healthcare providers should use simplified language, visual aids, and patient-centred discussions to enhance understanding and reduce parental anxiety. Radiographers should allocate sufficient time for discussions, involve referring physicians when necessary, and document the informed consent process thoroughly. Addressing these issues can improve patient experiences and contribute to positive health outcomes in resource-constrained settings.

Introduction
This study aims to evaluate the effects of a novel noise reduction software (INR, Canon Europe, Amsterdam, NL) on image quality (IQ) in Digital Radiography (DR) pelvic phantom images.
Methods
In total, 53 pelvic phantom images and 360 technical images of a Contrast Detail Radiography phantom (CDRAD) were collected, including 8 different exposure levels (between 0.8 and 40 mAs at 70 kV) and 6 intensities of INR (ranging from settings 0–10). The pelvic images were evaluated by three reporting radiographers using absolute Visual Grading Analysis (VGA). The CDRAD images were analyzed with a CDRAD computer software.
Results
The VGA showed that the images with the INR software had higher IQ than the images with no INR. The observers gave a high VGA score to the images with INR of 3.2 mAs and higher. There was a tendency for an INR level of 5 or 7 to give the highest VGA scores. In addition, the CDRAD study showed a significant improvement in IQ with increasing INR levels at the lower exposure levels.
Conclusion
An improvement in overall IQ was seen at lower exposure levels when the INR software was used both for the VGA and the CDRAD study. Clinical tests including patient images need to be performed before implementing INR in practice to verify accurate diagnostic performance.

Introduction
The escalating use of Computed Tomography (CT) has promoted higher radiographer workload, which can contribute to an increase of risks such as stress, job dissatisfaction, and potential health and safety issues. This study aimed to assess the impact of organizational, spatial, and temporal factors on procedures and workload in a CT unit, emphasizing patient safety and radiographer well-being. Addressing time pressure and optimizing workplace ergonomics are crucial in maintaining a balance between efficiency and quality, ensuring safe practices in modern medical imaging units.
Methods
The study was conducted in a Swiss university hospital CT unit and employed the Systems Engineering Initiative for Patient Safety (SEIPS) model to analyse the radiographers' workflow and time constrains. Observations and tasks’ analysis were used to collect data, including timing and location of tasks performed by radiographers.
Results
The radiographers’ workflow in the CT department is complex, involving multiple tasks. The entire process spans from 26 to 41 min but the Machine-Time (time spent inside the CT room) ranged from 10 to 16 min. The study identified inefficiencies in the workflow, namely in time spent on patient preparation and unsuited machine-time rate. The layout of the department, including limited space in the preparation area, contributing to ergonomic challenges for radiographers. Organizational factors, such as scheduling practices, also impacted workflow. The examination durations varied by type of scan and patient, leading to time pressure and potential safety concerns.
Conclusions
The study highlighted the need for more realistic time allocation in CT examinations to improve patient and radiographer safety. Recommendations include extending machine-time rate, adapting examination durations based on the type of CT, and assigning a dedicated radiographer for order review. It is also crucial improving the working environment to accommodate ergonomic needs. Addressing these issues can enhance the efficiency and safety of CT departments, benefiting both patients and radiographers.
Implications for Practice
Healthcare organizations should consider these study recommendations to improve the efficiency and safety of CT departments.

{"title":"Time constraints and workload in the computed tomography department","authors":"Nisanthi Yoganathan , Cláudia Sá dos Reis , Florentino Serranheira","doi":"10.1016/j.jmir.2024.101799","DOIUrl":"10.1016/j.jmir.2024.101799","url":null,"abstract":"<div><h3>Introduction</h3><div>The escalating use of Computed Tomography (CT) has promoted higher radiographer workload, which can contribute to an increase of risks such as stress, job dissatisfaction, and potential health and safety issues. This study aimed to assess the impact of organizational, spatial, and temporal factors on procedures and workload in a CT unit, emphasizing patient safety and radiographer well-being. Addressing time pressure and optimizing workplace ergonomics are crucial in maintaining a balance between efficiency and quality, ensuring safe practices in modern medical imaging units.</div></div><div><h3>Methods</h3><div>The study was conducted in a Swiss university hospital CT unit and employed the Systems Engineering Initiative for Patient Safety (SEIPS) model to analyse the radiographers' workflow and time constrains. Observations and tasks’ analysis were used to collect data, including timing and location of tasks performed by radiographers.</div></div><div><h3>Results</h3><div>The radiographers’ workflow in the CT department is complex, involving multiple tasks. The entire process spans from 26 to 41 min but the Machine-Time (time spent inside the CT room) ranged from 10 to 16 min. The study identified inefficiencies in the workflow, namely in time spent on patient preparation and unsuited machine-time rate. The layout of the department, including limited space in the preparation area, contributing to ergonomic challenges for radiographers. Organizational factors, such as scheduling practices, also impacted workflow. The examination durations varied by type of scan and patient, leading to time pressure and potential safety concerns.</div></div><div><h3>Conclusions</h3><div>The study highlighted the need for more realistic time allocation in CT examinations to improve patient and radiographer safety. Recommendations include extending machine-time rate, adapting examination durations based on the type of CT, and assigning a dedicated radiographer for order review. It is also crucial improving the working environment to accommodate ergonomic needs. Addressing these issues can enhance the efficiency and safety of CT departments, benefiting both patients and radiographers.</div></div><div><h3>Implications for Practice</h3><div>Healthcare organizations should consider these study recommendations to improve the efficiency and safety of CT departments.
