Introduction
Manual clipping in brain MR angiography (MRA) is time-consuming and depends on operator experience. This study aimed to evaluate the effectiveness of an automatic clipping function (AutoClip) in improving workflow efficiency and maintaining image quality across different experience levels.
Methods
Thirty brain MRA datasets were processed by three technologists with 12, 5, and 1 years of MRI experience using both manual and automatic clipping. Processing time was measured, and image quality was visually assessed using a five-point scale for major intracranial arteries.
Results
AutoClip significantly reduced processing time for all operators, with the largest reduction observed in the least experienced operator. Visual assessment showed comparable image quality between manual and automatic methods, independent of experience level.
Conclusion
AutoClip may maintain diagnostic image quality while substantially reducing post-processing time, particularly benefiting less-experienced operators and potentially improving overall workflow efficiency.
Implications for practice
The AutoClip function could enhance workflow efficiency and standardize MRA post-processing across operators with varying experience levels.

Introduction
Radiography students experience high stress from academic and clinical demands; ineffective coping can lead to burnout and reduced academic performance. Few studies have examined the influence of Grade Point Average (GPA) and class level on coping strategies among radiography students. This study aims to investigate stress management strategies among radiography students and assess the impact of GPA and class level.
Methods
A cross-sectional survey was conducted among 608 radiography students in Egypt, the UAE, and Jordan between April and June 2024. The questionnaire included demographics, GPA, class level, and coping strategies. Data were analyzed using SPSS version 20.0. Chi-square and Fisher's exact tests were used to evaluate associations at p < 0.05.
Result
Most participants were female (70.4 %) and aged 18–22 years. Class level did not significantly affect coping strategies (χ2 or FET as appropriate; p > 0.05). Common strategies included breaks (50.3 %) and weekly exercise (31.9 %). Overeating was reported by 47 %, decreasing from freshmen (56.1 %) to seniors (43.2 %). GPA showed significant associations. High GPA students more often took breaks (52.9 %, p = 0.010), engaged socially (39.4 %, p = 0.038), and were less likely to use drugs (p = 0.009), prescription medication (p = 0.022), or smoke (p = 0.001). Meditation was less frequent among high GPA students (30.8 %, p = 0.015).
Conclusion
Class level had little influence, while GPA strongly shaped coping. A high GPA was associated with adaptive behavior, whereas a low GPA was associated with substance use and maladaptive strategies.
Implications for practice
Institutions should promote adaptive coping, reduce harmful behavior, and tailor interventions to academic profiles to improve well-being and outcomes.

Introduction
This systematic review and meta-analysis evaluated the technical performance of dual-energy CT (DECT) in improving contrast resolution for hypovascular liver metastases.
Methods
A comprehensive literature search of MEDLINE and EMBASE was conducted from November 2024 to January 2025. Eligible studies assessed DECT for identifying hypovascular liver metastases and reported quantitative DECT metrics, including differences in Hounsfield units (ΔHU), contrast-to-noise ratio (CNR), or signal-to-noise ratio (SNR). A random-effects meta-analysis was performed to pool ΔHU, CNR, and SNR values derived from 40-keV virtual monoenergetic images and to compare them with reference single-energy CT (SECT) data.
Results
Out of 207 identified records, 12 studies met the inclusion criteria, encompassing a total of 698 patients. The pooled liver ΔHU in DECT was 164 ΔHU (95%CI 107–221 HU, p < 0.001, I2 = 80 %), significantly higher than values found in literature for SECT. Pooled CNR was 5.53 (95 % CI 4.12–6.95, p < 0.001, I2 = 72 %), comparable to that of SECT, while the pooled SNR was 9.71 (95 % CI 3.62–15.80, p = 0.002, I2 = 72 %), slightly lower than SECT.
Conclusion
Compared with SECT, DECT has not demonstrated consistent technical superiority for imaging hypovascular liver metastases. Standardized acquisition protocols are needed to minimize heterogeneity and improve reproducibility.
Implications for practice
Although DECT provides advanced post-processing options and potential for contrast dose reduction, it may entail radiation doses comparable to or slightly higher than SECT depending on the scanner platform and acquisition protocol. Its use in routine assessment of hypovascular liver metastases remains limited, underscoring the need for standardized protocols, consistent reporting, and combined evaluation of both technical and diagnostic performance to define its clinical value.

Introduction
Proper clinical management requires accurate differentiation of benign and malignant endometrial lesions. Intravoxel Incoherent Motion (IVIM) and Diffusion Kurtosis Imaging (DKI) are non-invasive MRI methods that have emerged as key tools in this differentiation. This systematic review compares the diagnostic accuracy of IVIM and DKI in evaluating endometrial lesions.
Methods
A systematic review of the literature was conducted using pertinent databases. Inclusion criteria were studies that compared IVIM and DKI for the differentiation of benign and malignant endometrial lesions and provided diagnostic performance statistics like area under the curve (AUC), specificity, and sensitivity. Meta-analysis was not performed in this review due to heterogeneity of the included studies, such as variation in b-values, magnetic field strengths of the MRI scanners, no standardized scanning parameters, and differences in Region of interest (ROI) selection as reported in the articles. The risk of bias was assessed using the QUADAS-2 tool.
Results
In total, 11 studies were included, which evaluated endometrial lesions. F, D, D∗, MD, and MK IVIM and DKI parameters had different diagnostic performances, with AUC ranging from 0.601 to 0.98. Sensitivity and specificity also differed widely between studies. The majority of studies used Echo Planar Imaging (EPI) sequences. Risk of bias assessment indicated moderate-to-high methodological quality.
Conclusion
IVIM and DKI could offer promising non-invasive methods for distinguishing endometrial lesions. Yet, differences in methodology and heterogeneity of studies emphasize the necessity for further standardization.
Implication of practice
IVIM and DKI MRI can be used as non-invasive quantitative tools to provide insights about tissue microstructure and perfusion characteristics which help clinicians in characterization of endometrial cancers.

Introduction
Breast cancer is the most frequently diagnosed cancer among Sri Lankan women, with over 3000 new cases reported annually and a mortality rate of approximately 4.7 per 100,000 women. This study evaluated breast cancer awareness among female undergraduates from government universities in Sri Lanka, on knowledge of risk factors, symptoms, screening methods and prevention.
Methods
A cross-sectional survey was conducted among 1002 female undergraduates (aged 20–28) from 12 government universities in Sri Lanka. A validated, self-administered questionnaire was used to collect data including demographics, breast cancer awareness, risk factors and screening methods. Descriptive statistics and one-way ANOVA were employed to analyse knowledge variations across faculties and age groups.
Results
The survey revealed that 98.7 % of respondents were aware of breast cancer. However, only 61.2 % recognised it as one of the most common cancers among women. Awareness of breast cancer screening methods revealed that the majority (54.5 %) were unaware of Breast Self-Examination (BSE), and only 42 % recognised the importance of mammograms even in the absence of symptoms. Knowledge scores varied by academic disciplines, with Health Sciences and Natural and Applied Sciences showing highest awareness. Additionally, awareness increased with age, peaking in the 26–28 years group compared to younger age groups.
Conclusion
The findings reveal significant knowledge gaps among female undergraduates regarding breast cancer risk factors and the importance of breast screening methods. Despite awareness, understanding of early detection methods is insufficient, highlighting the need for better education on preventive behaviours.
Implications for practice
Targeted educational programmes are essential to enhance breast cancer awareness, improve screening access, and encourage proactive behaviours such as breast self-examinations to enhance early detection and improve survival rates.

Introduction
Integrating magnetic resonance imaging (MRI) and stereotactic radiosurgery (SRS) has revolutionised cancer treatment, enhancing precision and improving patient outcomes. MRI/CT image fusion improves the visualisation of targets and surrounding tissues, supporting accurate radiotherapy planning. This study evaluates the impact of multidisciplinary cooperation between radiology and radiotherapy departments on MRI/CT image fusion, incorporating a thermomouldable cervical cushion during CT and MRI planning to optimise patient positioning.
Methods
This retrospective study analysed 200 MRI/CT co-registrations from patients treated at our institution between January 2023 and October 2024, divided into two groups: Group A (diagnostic MRI setup) and Group B (radiology/radiotherapy synergy with thermomouldable cervical cushion and laser alignment). Rotational deviations (pitch, roll, yaw) were extracted. Data were assessed for normality using the Kolmogorov–Smirnov test, and group comparisons were performed with an independent samples t-test (p < 0.05).
Results
Group B demonstrated significantly lower absolute rotational deviations than Group A across all axes (pitch, roll, yaw; p < 0.001). Mean absolute deviations were reduced from 7.44° to 3.46° for pitch (X-axis), 2.86°–1.59° for roll (Y-axis), and 4.18°–1.70° for yaw (Z-axis), confirming the impact of radiology/radiotherapy synergy on improving MRI/CT image-fusion alignment.
Conclusion
Multidisciplinary cooperation between the radiology and radiotherapy departments enabled the implementation of an improved MRI acquisition protocol for SRS planning. The introduction of a thermomouldable cervical cushion provided a simple, reproducible, and accessible solution to improve MRI/CT image-fusion quality, particularly valuable in hospitals without dedicated MRI scanners for radiotherapy.
Implications for practice
Multidisciplinary synergy between the radiology and radiotherapy departments significantly improved MRI and CT image co-registration, optimising precision in SRS planning, supported by the use of a thermomouldable cervical cushion.

Objective
To evaluate the stability of radiomic features derived from different segmentation methods in head and neck MRI of nasopharyngeal carcinoma (NPC), with a focus on the effect of the Histogram Matching Filter (HMF).
Methods
A total of 851 radiomic features, including tumor intensity, shape, and texture, were extracted from 30 manually segmented MRI scans. The same scans were also segmented using semi-automatic techniques and further enhanced using a Histogram Matching Filter (HMF) prior to segmentation. Segmentation was performed using a level tracing algorithm by two experienced radiologists. Intraclass correlation coefficients (ICC) were used to assess feature reproducibility and repeatability.
Results
Semi-automatic segmentation with HMF demonstrated the highest reproducibility. For T2-weighted images (T2WI), the ICC was 0.990 ± 0.019 (p < 0.005), and for contrast-enhanced T1-weighted images (CE-T1WI), the ICC was 0.987 ± 0.025 (p < 0.005). Conventional semi-automatic segmentation achieved lower ICCs: 0.905 ± 0.073 for T2WI and 0.922 ± 0.063 for CE-T1WI. Manual segmentation showed the lowest reproducibility with ICCs of 0.787 ± 0.134 for T2WI and 0.801 ± 0.131 for CE-T1WI (p > 0.005).
Conclusions
Incorporating HMF into the segmentation workflow significantly improves the reproducibility of radiomic features, especially in T2WI. This enhancement supports more consistent and reliable analyses in radiomic studies.
Implication of practice
The use of HMF-enhanced segmentation can reduce variability in radiomic feature extraction, promoting greater consistency in clinical decision-making and radiomic research involving NPC.

Introduction
The potential anxiety invoked by diagnostic imaging procedures intensifies in cancer diagnoses, with the term ‘scanxiety’ originating from the additional fear associated with cancer imaging. This emphasises the importance of a person-centred approach to care. This scoping review mapped the literature regarding imaging-related anxiety, ‘scanxiety’, and person-centred care.
Methods
Databases used were Cinahl Plus; Proquest; PubMed; Scopus; Web of Science; PsycINFO, and Cochrane. Broad search terms were utilised to maximise results, with specific inclusion and exclusion criteria. Limiters were English language articles within the previous 10 years. Further to systematic filtering and critical appraisal, 60 studies were included.
Results
Findings were organised in four themes: ‘Quantification and causes of anxiety’; ‘The nature of imaging procedures’; ‘Perceptions of Person-centredness’; and ‘Service and staffing factors’. MRI and PET/CT cause the highest procedural stress. Fear of results causes greater, and more sustained, anxiety in cancer patients than other groups, creating complex emotional needs. The physiological effects of anxiety can adversely affect image quality and ability to complete scans. Human interaction is central to managing anxiety, but service pressures and staff emotional labour influence care delivery. Most existing person-centred care research in imaging relates to generic populations, with limited focus on how diagnostic radiography staff can support people with cancer.
Conclusion
Although the psychosocial needs of those undergoing cancer imaging are greater than in other diagnoses, more research is needed into the benefits of a person-centred approach and the support and education needs of staff working in this field.
Implications for practice
Understanding experiences of cancer imaging, from both patient and staff perspectives, including any facilitators and barriers to care, would support development of a model for person-centred care in this specialist area.
导读：在癌症诊断中，诊断成像程序引发的潜在焦虑加剧，术语“扫描焦虑”源于与癌症成像相关的额外恐惧。这强调了以人为本的护理方法的重要性。本综述梳理了影像相关焦虑、“影像焦虑”和以人为本的护理方面的文献。方法：使用的数据库为Cinahl Plus；它;PubMed;斯高帕斯;Web of Science；PsycINFO和Cochrane。广泛的搜索词被用来最大化结果，并有特定的纳入和排除标准。限制因素是过去10年内的英文文章。经过系统筛选和批判性评价，纳入了60项研究。结果：调查结果分为四个主题：“焦虑的量化和原因”；“成像程序的性质”；“以人为中心的观念”；以及“服务和人员因素”。MRI和PET/CT引起最大的程序性应激。癌症患者对结果的恐惧导致了比其他群体更大、更持久的焦虑，产生了复杂的情感需求。焦虑的生理效应会对图像质量和完成扫描的能力产生不利影响。人与人之间的互动是控制焦虑的核心，但服务压力和工作人员的情绪劳动影响护理的提供。大多数现有的以人为中心的成像护理研究涉及一般人群，对放射诊断人员如何为癌症患者提供支持的关注有限。结论：尽管接受癌症成像的患者的心理社会需求大于其他诊断，但需要更多的研究来了解以人为本的方法的好处以及在该领域工作的工作人员的支持和教育需求。对实践的启示：从患者和工作人员的角度了解癌症成像的经验，包括任何促进因素和护理障碍，将有助于在该专业领域建立以人为本的护理模式。
