With the increase in the number of individuals diagnosed with HBOC, the demand for breast MRI surveillance is also rising. However, the current system is inadequate, with factors such as lack of knowledge and indifference among healthcare professionals, and insufficient understanding of breast MRI surveillance being cited. This study aims to investigate the knowledge of HBOC and the awareness of breast MRI surveillance among radiological technologists, and to analyze the factors that promote these practices.Methods: A web-based survey was conducted among radiological technologists at 1278 facilities with MRI installations.Results: Responses were obtained from 433 individuals. The knowledge of HBOC was insufficient, with 49.6% unaware that breast MRI surveillance is recommended. Factors promoting awareness included the amount of knowledge about HBOC, age, and the presence of MRI specialists and mammography screening specialists.Conclusion: By enhancing the acquisition of knowledge about HBOC and raising awareness of breast MRI surveillance, it is expected that discussions towards building a robust system will deepen.","PeriodicalId":74309,"journal":{"name":"Nihon Hoshasen Gijutsu Gakkai zasshi","volume":"81 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using this model, we extracted three regions from 1544 MLO images and generated mask images. The mask of the breast silhouette was automatically created using image processing techniques, resulting in a total of four mask images per image for 1544 MG. Afterward, we annotated those mask images and developed an AI model (Score Evaluation Model) for evaluating positioning with scores. The evaluation included six items: the insertion and shape of the pectoralis major muscle, the gap between the pectoralis major and the mammary gland, the extent of the mammary region, the breast silhouette, and the direction of stretching. We developed a system that quantifies MG positioning using AI-based scoring.Results: For the mask generation model, the DICE coefficient, which indicates the concordance of region extraction, was 0.968. For the score evaluation model, the accuracy of the six models was 0.825 or higher, and the AUC values from the ROC analysis were 0.873 or higher, indicating high performance.Conclusion: A system that evaluates positioning with a score has been developed. The scores assigned to the specific items can be utilized as quantitative indicators for future technical support.","PeriodicalId":74309,"journal":{"name":"Nihon Hoshasen Gijutsu Gakkai zasshi","volume":"81 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145016888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
