Ultrasound elastography is a low-cost, accessible, and noninvasive diagnostic tool capable of estimating liver elasticity in patients with HCC. However, due to the heterogeneity of the articles included in this review, further prospective studies are needed in order to confirm and standardize a cutoff stiffness value for early HCC screening, which could improve patient outcomes, particularly in resource-limited settings.","PeriodicalId":20842,"journal":{"name":"Radiologia Brasileira","volume":"58 ","pages":"e20240108"},"PeriodicalIF":0.0,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12157276/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144275838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the decades, various classifications have been developed to categorize these anomalies. Based on a classification proposed by Kaufmann and Jarcho in 1946, the classification devised by the American Fertility Society in 1988 was considered simple and practical; although it faced criticism for its subjectivity and limitations in classifying complex anomalies, it was widely adopted. In 2013, the European Society of Human Reproduction and Embryology and the European Society for Gynaecological Endoscopy introduced a more detailed classification, which, albeit more complex and with a risk of overdiagnosis, also included cervical and vaginal anomalies. In 2021, the American Society for Reproductive Medicine updated the classification with the aim of simplifying and improving diagnostic accuracy, expanding the categories, and defining more objective criteria. This new classification seeks to facilitate communication among professionals and enhance clinical management, emphasizing the importance of continuous updates to improve reproductive outcomes and the quality of life for patients affected by these anomalies. This article aims to discuss the strengths and limitations of each of these classifications, offering a critical analysis of their impact on the diagnosis and treatment of müllerian anomalies. It also seeks to highlight aspects that may be refined in future revisions to achieve greater diagnostic precision and clinical applicability.","PeriodicalId":20842,"journal":{"name":"Radiologia Brasileira","volume":"58 ","pages":"e20240096"},"PeriodicalIF":0.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12139404/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144234956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was pretrained on 28,506 CT images from The Cancer Image Archive, a private database, and validated on 2,015 of those images. To develop the classification algorithm, we used a VGG16-based network, modified for better performance, with 3,080 images of adenocarcinoma and SCC from the Instituto Nacional de Câncer database.Results: The algorithm achieved an accuracy of 84.5% for detecting adenocarcinoma and 89.6% for detecting SCC, with sensitivities of 91.7% and 90.4%, respectively, which are considered satisfactory when compared with the values obtained in similar studies.Conclusion: The system developed appears to provide accurate automated detection, as well as tumor segmentation and classification of NSCLC subtypes of a local population using deep learning networks trained using public image data sets.

Five axial MRF slices of the bladder were obtained before and after voiding. Regions of interest were annotated on MRF T1 maps: one on the anterior bladder wall, and one on a lateral wall. Annotations made on T1 maps were subsequently copied to coregistered T2 maps. Student's t-tests for paired samples were employed to compare the T1 and T2 values obtained before voiding with those obtained after voiding.Results: Eight volunteers were included. The mean preand post-void T1 relaxation times were 1,575 ± 93 ms and 1,476 ± 138 ms, respectively. The mean preand post-void T2 relaxation times were 55 ± 21 ms and 53 ± 8 ms, respectively.
