Often pregnant women in low-middle-income countries like Nigeria register for antenatal care late in pregnancy, necessitating the need for a single, cost-effective parameter that requires minimal skills to measure gestational age accurately in late pregnancies.

Accurate diagnosis from chest X-rays is critical yet challenging due to subtle manifestations of TB, particularly in its early stages. Traditional computational methods, primarily using basic convolutional neural networks (CNNs), often require extensive pre-processing and struggle with generalizability across diverse clinical environments. This study introduces a novel Vision Transformer (ViT) model augmented with Gradient-weighted Class Activation Mapping (Grad-CAM) to enhance both diagnostic accuracy and interpretability. The ViT model utilizes self-attention mechanisms to extract long-range dependencies and complex patterns directly from the raw pixel information, whereas Grad-CAM offers visual explanations of model decisions about highlighting significant regions in the X-rays. The model contains a Conv2D stem for initial feature extraction, followed by many transformer encoder blocks, thereby significantly boosting its ability to learn discriminative features without any pre-processing. Performance testing on a validation set had an accuracy of 0.97, recall of 0.99, and F1-score of 0.98 for TB patients. On the test set, the model has accuracy of 0.98, recall of 0.97, and F1-score of 0.98, which is better than existing methods. The addition of Grad-CAM visuals not only improves the transparency of the model but also assists radiologists in assessing and verifying AI-driven diagnoses. These results demonstrate the model's higher diagnostic precision and potential for clinical application in real-world settings, providing a massive improvement in the automated detection of TB.</p>","PeriodicalId":9020,"journal":{"name":"BMC Medical Imaging","volume":"25 1","pages":"96"},"PeriodicalIF":2.9,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11934573/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
