Résumé:

Introduction L'intelligence artificielle (IA) est de plus en plus utilisée dans la pratique de l'imagerie médicale, mais son impact sur la pratique des radiographes n'est pas bien étudié. Le but de cette étude était d'explorer l'impact perçu de l'IA sur les activités et la profession des radiographes en Suisse. Méthodologie Une enquête menée au Royaume-Uni, a été traduite en français et en allemand et diffusée par l'intermédiaire d'organismes professionnels et des médias sociaux. Les participants étaient des radiographes suisses (cliniciens/éducateurs/chercheurs/étudiants) et des médecins travaillant dans le domaine de l'imagerie médicale (radiologie/médecine nucléaire/radio-oncologie). L'enquête comportait cinq sections : données démographiques, connaissances en matière d'IA, compétences, confiance, perceptions de l'impact de l'IA. Des statistiques descriptives et d'association ainsi qu'une analyse thématique qualitative ont été réalisées. Résultats Au total, 242 réponses ont été recueillies (89 % de radiographes, 11 % de médecins). L'IA est utilisée par 43 % des participants dans la pratique clinique, mais 64 % d'entre eux ne se sentent pas à l'aise avec la terminologie de l'IA. Les participants considèrent l'IA comme une opportunité (57 %), tandis que 19 % la considèrent comme une menace. Les opportunités étaient associées à la rationalisation des tâches répétitives, à la réduction des erreurs, à l'augmentation du temps consacré aux soins centrés sur le patient, à la recherche et à la sécurité du patient. Les principales menaces identifiées sont la réduction des postes de travail (23 %) et la diminution du niveau d'expertise des radiographes en raison du biais de l'automatisation (16 %). Les participants (68 %) ne se sentent pas bien formés/préparés à la mise en œuvre de l'IA dans leur pratique, soulignant l'absence de formation spécifique (88 %). 93 % des participants ont indiqué que l'enseignement de l'IA devrait être inclus dans les programmes de formation de premier cycle. Conclusion Bien que la plupart des participants perçoivent l'IA comme une opportunité, cette étude a identifié des domaines à améliorer, notamment le manque de connaissances, de soutien pédagogique/de formation et de confiance chez les radiographes. Une formation personnalisée doit être mise en œuvre pour améliorer la pratique clinique et la compréhension de la manière dont l'IA peut bénéficier aux radiographes.

Résumé:

Aims : To identify image quality criteria that can be applied to assess breast implant (BI) mammograms according to radiologists and radiographers’ perspectives and to explore the level of agreement about criteria priority. Methods : A two-round Delphi method using a questionnaire was applied to identify the level of agreement between experts, asking them to rank each image criteria available for mammography according to 4 possible answers (1 = need to have, 2 = nice to have, 3 = not pertinent/appropriate, 4 = do not know). Criteria for craniocaudal (CC), mediolateral-oblique (MLO) and lateral (ML), with and without Eklund manoeuvre, were included. This process was repeated after removing the less relevant criteria. Results : Between first and second rounds, different results were obtained regarding the criteria to assess CC and MLO images. Details for anatomic areas were considered the most relevant by radiographers during the first round, while general criteria were prioritised during the second round. Radiologists focused more on analysis of the spread of the breast tissue, if the breast was aligned with detector’s centre and level of contrast. The analysis of implant flow, the BI anterior edge and the maximum retropulsion of BI when Eklund manoeuvre is performed were the specific aspects of BI imaging considered as relevant for assessment. Conclusions : The importance of each criterion used to assess BI mammograms was not the same between radiographers and radiologists, suggesting the two groups of experts are looking for different requirements from the image. Further education and training is necessary to align strategies for assessing BI mammograms, and some criteria need to be adapted to reduce subjectivity.

Résumé:

Purpose : To characterise the mammography technique used in breast cancer screening programmes for breast implants (BI) and to identify if the image quality (IQ) criteria available in literature are applicable to BI imaging. Methods : The study was conducted in two phases: literature review to find IQ criteria used in mammography combining keywords in several sources; and assessment of 1207 BI mammograms using the criteria that was identified previously to see if they were achieved or not. An observation grid was used to collect information about positioning, beam energy, compression force, and exposure mode. Descriptive statistics and Student’s t test and χ2 test were performed according to the nature of the variables. Results : Forty-seven out of 2188 documents were included in the analysis, with 13 items identified to assess the quality of positioning, 4 for sharpness, 3 for artefacts, and 2 for exposure parameters. After applying the criteria to BI mammograms, retroglandular fat was not included in 37.3% of the images. The “Pectoral-Nipple-Line” criterion was achieved in 35% of MLO/ML images. The placement of the implant (subpectoral/subglandular) or performing the Eklund had significant influence on the visible anatomy (p = < 0.005), alongside whether the breast was aligned to the detector’s centre. Conclusions : Some of the criteria used to assess standard mammograms were not applicable to BI due to implant overlap. The alignment of the image with the detector’s centre seems to have an impact on the amount of visible tissue. Further studies are necessary to define the appropriate protocol, technique, and suitable quality criteria to assess BI mammograms.

Résumé:

Objectives: The aim of the study was to complete a collaborative review of Radiography continuing professional development (CPD) research material to support the production of European Federation of Radiographer Societies (EFRS) CPD recommendations. A meta-ethnography approach to literature review was applied focussing upon commonalities rather than discrepancies between research outcomes. This facilitated exploration of context across the geographical region of Europe with national variations in CPD governance. The seven phases of the meta-ethnographic approach were followed by two independent experienced researchers. A third researcher mediated the findings which were then explored collaboratively with the EFRS CPD working group for concordance. Key Findings: Phase seven of the meta-ethnography involved interpreting an expression of the synthesis from the previous stages. Six main corroborating themes emerged in this process and following mediation were expressed as themes; knowledge, skills & competency, needs/gap analysis, multi-layered/ multi-modal, barriers and drivers; regulation vs autonomy; fostering collaboration e harnessing technology. Conclusion: The primary feature of CPD activity should be the resulting impact e to patients, the service, the profession and the individual; with all stakeholders working in partnership. CPD activity must be flexible/multi-modal to support the changing growth/dynamic workforce. All stakeholders should utilise communication and technology resources and make efforts to improve collaboration between the management, regulators and educators to support Radiographers to develop meaningful CPD. Health services across Europe are under increasing stress and a principal factor going forwards will be managing increasing demands on healthcare staff whilst supporting enhancement of the knowledge, skills and competency base.
