Abstract Objective: Summarize the impact generated by the introduction of the molecular classification of breast cancer in the different specialties involved so as to offer radiologists a global view of the current management of this disease, from diagnosis to treatment. Findings: In the last two decades, molecular information based on genomic analysis has helped to understand the biological diversity of breast cancers and generated profound changes in the clinical oncological practice. With simpler and available immunohistochemical tests, it is possible to approximate the molecular classification, enabling the prediction of clinical behavior of the different subtypes (Luminal, HER2-positive, Triple-negative) and their response to different therapies, facilitating the design of personalized treatments. Although no findings absolutely pathognomonic have been described in mammography, ultrasound or magnetic resonance imaging, the molecular classification concept has already two concrete uses: for predicting Luminal A or Triple-negative phenotype on images and for evaluating the neoadjuvant chemotherapy response by magnetic resonance. A future application is expected in the area of radiogenomics. Conclusions: Radiologists dedicated to breast imaging should be familiar with the concepts of molecular classification, necessary for radio-pathological correlation of breast biopsy results and in order to provide an optimal patient care.","PeriodicalId":35339,"journal":{"name":"Revista Chilena de Radiologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48375953","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}

Abstract Artificial intelligence algorithms have developed a great advance in image recognition related tasks, being able to identify complex patterns and providing quantitative information. This paper shows the design process of two new Deep Learning models, the first one capable of classifying thoracic structures and the presence of cardiomegaly; the second one allows posterior rib arches autonomous segmentation in posterior-anterior chest X-rays. The results showed 100% accuracy for the thoracic structures classification model, while for the cardiomegaly identification model, the accuracy was 99.2 ± 0.8%. The second autonomous segmentation model showed 93 ± 29.0% accuracy. Based on these results and with the current Deep Learning development, we consider this tool will help automate processes that will facilitate the task of all those who are related to diagnostic imaging.","PeriodicalId":35339,"journal":{"name":"Revista Chilena de Radiologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43536925","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}
