Implementing supplementary breast cancer screening in women with dense breasts: Insights from European radiographers and radiologists.

INTRODUCTION: In response to the critical need for enhancing breast cancer screening for women with dense breasts, this study explored the understanding of challenges and requirements for implementing supplementary breast cancer screening for such women among clinical radiographers and radiologists in Europe. METHOD: Fourteen (14) semi-structured online interviews were conducted with European clinical radiologists (n = 5) and radiographers (n = 9) specializing in breast cancer screening from 8 different countries: Denmark, Finland, Greece, Italy, Malta, the Netherlands, Switzerland, United Kingdom. The interview schedule comprised questions regarding professional background and demographics and 13 key questions divided into six subgroups, namely Supplementary Imaging, Training, Resources and Guidelines, Challenges, Implementing supplementary screening and Women's Perspective. Data analysis followed the six phases of reflexive thematic analysis. RESULTS: Six significant themes emerged from the data analysis: Understanding and experiences of supplementary imaging for women with dense breasts; Challenges and requirements related to training among clinical radiographers and radiologists; Awareness among radiographers and radiologists of guidelines on imaging women with dense breasts; Challenges to implement supplementary screening; Predictors of Implementing Supplementary screening; Views of radiologists and radiographers on women's perception towards supplementary screening. CONCLUSION: The interviews with radiographers and radiologists provided valuable insights into the challenges and potential strategies for implementing supplementary breast cancer screening. These challenges included patient and staff related challenges. Implementing multifaceted solutions such as Artificial Intelligence integration, specialized training and resource investment can address these challenges and promote the successful implementation of supplementary screening. Further research and collaboration are needed to refine and implement these strategies effectively. IMPLICATIONS FOR PRACTICE: This study highlights the urgent need for specialized training programs and dedicated resources to enhance supplementary breast cancer screening for women with dense breasts in Europe. These resources include advanced imaging technologies, such as MRI or ultrasound, and specialized software for image analysis. Moreover, further research is imperative to refine screening protocols and evaluate their efficacy and cost-effectiveness, based on the findings of this study.

An exploration of factors involved in the roll out of a digital application in breast services: A case study approach.

INTRODUCTION: Acceptance of new technologies in health care, by those who use them as part of their role, is challenging with confounding contextual factors surrounding the acceptance of technology. As healthcare is rapidly digitising, stakeholder groups should be included in each stage of evaluation and implementation to allow opportunities to influence and contribute to digital health policies. This research employed a case study methodology to initiate an exploration into the factors associated with implementing a digital application into a mammography service. It examined the initial implementation and subsequent impact of the rollout of a digital application (VA) within a breast service in South Australia. METHODS: Stakeholders' opinions on team performance and feedback mechanisms of the digital application were evaluated through a staff questionnaire distributed through an online survey JISC. RESULTS: The incorporation of digitised technology into a service is evidently met with challenges. Although there is potential value in utelising automated feedback for workflow improvement and patient services, it appears imperative to provide targeted and developmental resources for educational development and staff well-being during the implementation phase. CONCLUSION: This case study approach delves into key discussion areas and serves as the initial insight into the implementation of a digital application. It could be regarded as a foundational reference for future evaluations of digital applications. IMPLICATIONS FOR PRACTICE: Research around digital fluency within the radiography profession requires further consideration. Under-utilisation or resistance may result in missed opportunities to enhance patient experiences and care outcomes and support staff wellbeing. Therefore, continued engagement and the encouragement of user feedback during the implementation phase are crucial to demonstrate future acceptance of digital applications in clinical settings.

Assessing the impact of binaural and non-binaural auditory beat intervention to pain and compression in mammography.

INTRODUCTION: Pain and discomfort has a negative impact on a patient's overall experience and may impact on subsequent re-attendance to mammography. Pain during mammography remains a significant issue. Assessment of interventions to reduce levels of pain associated with mammography are essential to increase attendance to breast services and improve user experience. METHODS: Participants (n = 60) were invited to take part in the study at one hospital Trust within the UK. Postal invitations were sent 2 weeks prior to appointment to patients older than 40 years with previous mammography attendance at the same Trust to allow for comparison of previous and current pain scores/compression values. Patients were randomised into 3 groups: Binaural music (BM), non-binaural music (NBM) and standard care (C). A numerical rating scale (NRS) was used to rate pain. RESULTS: Patient tolerance is increased by the application of both the non-binaural and binaural music. Binaural music was most effective in improving patient tolerance (p = 0.02). When applied compression increased some patients recorded less pain, which may have implications to image quality and radiation dose for patients. Binaural music reduces the perception of mammographic pain within this data set. CONCLUSION: 5 min exposure to binaural music improves patient experience and tolerance for mammography which could be utilised to improve attendance rates in screening and symptomatic services. IMPLICATIONS FOR PRACTICE: There is an indication for further research looking at application prior and during interventional biopsies. Music intervention can be offered to patients in the severe pain category who refuse mammography. It is acknowledged from these findings that the introduction of BM and NBM prior to mammography would be a low risk, cost effective intervention within the hospital setting.

A comparative study of pain experienced during successive mammography examinations in patients with a family history of breast cancer and those who have had breast cancer surgery.

INTRODUCTION: To measure mammography-related pain in two groups of women undergoing regular surveillance as a baseline for future care. METHODS: Following ethical approval, two hundred and forty two women aged 32-84 years (mean 54), were invited by written invitation to participate in the study. Two hundred women accepted the invitation, 100 women had a family history (FH) of breast cancer, 100 had undergone conservative surgery (FU) for breast cancer and were currently asymptomatic. A validated pain scale was used to score the participants' perceived pain before compression based on memory, immediately after compression and one week later. A series of baseline parameters were also captured including compression force, breast size/density, menstrual history and any adverse events following mammography to allow the investigation of relationships. RESULTS: There was a strong correlation (r = 0.79, p < 0.001) between previous pain scores and current pain scores, no significant correlations were found between breast size, breast density or total compression force and pain. Pain scores reduced between previous and current examinations and there was consistency in overall pain scores, despite variations in the compression forces applied. CONCLUSION: Physical side effects from mammography can develop and extend beyond the examination period. Patients' prior experience of pain was the only significant predictor of current pain in this study. IMPLICATIONS FOR PRACTICE: Data on past mammography experiences are essential to improve future pain outcomes. Post-mammography aftercare should be a routine feature of the examination.

Learning to look: Evaluating the student experience of an interactive image appraisal activity.

INTRODUCTION: Student radiographers have expressed difficulty in performing image appraisal tasks. The purpose of this study was to investigate the value of a workshop delivered to level 4 undergraduate students. All students completed an image appraisal activity, inputting their appraisal into software that displayed their response alongside an expert opinion. They were asked to identify and discuss any discrepancy. METHODS: All Level 4 students participated in an image appraisal workshop and were subsequently invited to take part in a focus group immediately after the activity. Twenty-three students took part in three focus groups (n = 7; n = 8; n = 8). A thematic analysis of transcripts was performed alongside validation from observations during the image appraisal activity. RESULTS: Findings demonstrate that despite teaching and resources being available, students had focused on learning a generic checklist for image appraisal, had not appreciated the application of projection specific criteria and felt underprepared. The use of specific criteria and repetition within the task was considered useful. They identified learning needs and misconceptions through peer discussion and via the expert opinion, highlighting the value of feedback. Students enjoyed the workshop and made suggestions for implementation into the curriculum. CONCLUSION: Educators must not assume that the provision of resources will result in students developing deep knowledge. Teaching and learning strategies that are task specific are recommended to avoid a surface approach to learning. Time, repetition and appropriate feedback are essential to enable learners to develop competence and confidence for complex visual tasks, such as image appraisal.

Effective lifetime radiation risk for a number of national mammography screening programmes.

BACKGROUND AND PURPOSE: The performance of mammography screening programmes is focussed mainly on breast cancer detection rates. However, when the benefits and risks of mammography are considered, the risk of radiation-induced cancer is calculated for only the examined breast using Mean Glandular Dose (MGD). The risk from radiation during mammography is often described as low or minimal. This study aims to evaluate the effective lifetime risk from full field digital mammography (FFDM) for a number of national screening programmes. MATERIAL AND METHODS: Using an ATOM phantom, radiation doses to multiple organs were measured during standard screening mammography. Sixteen FFDM machines were used and the effective lifetime risk was calculated across the female lifespan for each machine. Once the risks were calculated using the phantom, the total effective lifetime risk across 48 national screening programmes was then calculated; this assumed that all these programmes use FFDM for screening. RESULTS: Large differences exist in effective lifetime risk, varying from 42.21 [39.12-45.30] cases/106 (mean [95% CI]) in the Maltese screening programme to 1099.67 [1019.25-1180.09] cases/106 for high breast cancer risk women in the United States of America. These differences are mainly attributed to the commencement age of screening mammography and the time interval between successive screens. CONCLUSIONS: Effective risk should be considered as an additional parameter for the assessment of screening mammography programme performance, especially for those programmes which recommend an early onset and more frequent screening mammography.

Practitioner compression force variability in mammography: a preliminary study.

OBJECTIVE: This preliminary study determines whether the absolute amount of breast compression in mammography varies between and within practitioners. METHODS: Ethics approval was granted. 488 clients met the inclusion criteria. Clients were imaged by 14 practitioners. Collated data included Breast Imaging Reporting and Data System (BI-RADS) density, breast volume, compression and practitioner code. RESULTS: A highly significant difference in mean compression used by different practitioners (p<0.0001 for each BI-RADS density) was demonstrated. Practitioners applied compression in one of three ways using either low, intermediate or high compression force, with no significant difference in mean compression within each group (p=0.99, p=0.70, p=0.54, respectively). Six practitioners showed a significant correlation (p<0.05) between compression and BI-RADS grade, with a tendency to apply less compression with increasing BI-RADS density. When compression was analysed by breast volume there was a wide variation in compression for a given volume. The general trend was the application of higher compression to larger breast volumes by all three practitioner groups. CONCLUSION: This study presents an insight into practitioner variation of compression application in mammography. Three groups of practitioners were identified: those who used low, intermediate and high compression across the BI-RADS density grades. There was wide variation in compression for any given breast volume, with trends of higher compression demonstrated for increasing breast volumes. Collation of further studies will facilitate a new perspective on the analysis of practitioner, client and equipment variables in mammography imaging. ADVANCES IN KNOWLEDGE: For the first time, it has been practically demonstrated that practitioners vary in the amount of compression applied to breast tissue during routine mammography.

Sequential 3D X-ray microtomographic measurement of enamel and dentine ablation by an Er:YAG laser.

OBJECTIVE: To demonstrate the progression of crater growth during repeated sequential application of an Er:YAG laser to enamel and dentine, monitored using X-ray microtomography (XMT). DESIGN: A single centre study in which laser craters were created in blocks cut from human enamel and/or dentine under standardised and known conditions and then studied using XMT to obtain visualisation and quantification of the effects. SETTING: University setting, UK, 2001. MAIN OUTCOME MEASURES: Success was judged by an ability to obtain useful 3D XMT reconstructions of the blocks during crater development, and to make measurements from these data. These measurements were compared with data obtained from similar studies using different measurement techniques. RESULTS: Time sequences of 2D and 3D images were obtained which demonstrated the progression of laser craters in enamel and dentine. Quantitative measurements from these data enabled values to be derived for the rate of progression of crater depth per unit energy, and the volume of hard tissue removed per unit energy. These values were compared with data derived from other studies and shown to be broadly comparable. However, the present study is unique in that these values were obtained from a series of measurements of the same craters over time. CONCLUSIONS: 3D X-ray microtomography is shown to be a useful tool for quantitative measurements in dental research. For the Er:YAG laser, the relationship of laser crater depth and volume of mineral removed to applied energy was found to be linear.

Microtomographic analysis of subsurface enamel and dentine following Er:YAG laser and acid etching.

The Er:YAG laser, with or without phosphoric acid, is used to promote enamel surface changes to increase restorative material retention. However, such irradiation might induce subsurface enamel damage. In the present study, X-ray microtomography was used to compare the subsurface enamel beneath laser and acid conditioned; laser-only etched and acid-only etched surfaces. Laser and acid conditioning increased the etching depth, but did not induce significant damage in the enamel subsurface. Analysis of the laser-only etched enamel subsurface revealed a small reduction in mineral concentration suggesting an increase in porosity, allowing greater penetration of acid and resulting in an increased acid-etch depth.

X-ray microtomography: a novel technique for the quantification of effects in enamel following CO2 laser application.

X-ray microtomography (XMT) is a miniaturised version of the technique of computer axial tomography as used in medical diagnosis. As an example of the dental research applications of the technique, a pilot study is described in which the effects of a continuous wave carbon-dioxide laser on dental enamel are investigated and the use of XMT for the non-invasive measurement of mineral density changes within dental hard tissues is demonstrated. The results show clearly the ability of XMT to display graphically, and to quantify, changes in mineral density occurring within lased specimens, compared with a conventional SEM view of similar material. There have been many reports of the problems found when using lasers to cut dental hard tissues, and this paper demonstrates that XMT is of particular value in the study of the cracking induced by many lasers. We also suggest that XMT might be used in many studies investigating mineral density changes within dental hard tissues.
