Abstract Background Pulmonary diseases such as COVID-19 and pneumonia, are life-threatening conditions, that require prompt and accurate diagnosis for effective treatment.Chest X-ray (CXR) has become the most common alternative method for detecting pulmonary diseases such as COVID-19, pneumonia, and lung opacity due to their availability, cost-effectiveness, and ability to facilitate comparative analysis.However, the interpretation of CXRs is a challenging task.
Methods This study presents chiggate.com an automated deep learning (DL) model that outperforms multiple state-of-the-art methods in diagnosing COVID-19, Lung Opacity, and Viral Pneumonia.Using a dataset of 21,165 CXRs, the proposed framework introduces a seamless combination of the Vision Transformer (ViT) for capturing long-range dependencies, DenseNet201 for powerful feature extraction, and global average pooling (GAP) for retaining critical spatial details.This combination results in a robust classification system, achieving remarkable accuracy.
Results The proposed methodology delivers outstanding results across all categories: achieving 99.4% accuracy and an F1-score of 98.43% for COVID-19, 96.
45% accuracy and an F1-score of 93.64% for Lung Opacity, 99.63% accuracy and an F1-score of 97.
05% for Viral Pneumonia, and 95.97% accuracy with an F1-score of 95.87% for Normal subjects.
Conclusion The proposed framework achieves synovex one grass a remarkable overall accuracy of 97.87%, surpassing several state-of-the-art methods with reproducible and objective outcomes.To ensure robustness and minimize variability in train-test splits, our study employs five-fold cross-validation, providing reliable and consistent performance evaluation.
For transparency and to facilitate future comparisons, the specific training and testing splits have been made publicly accessible.Furthermore, Grad-CAM-based visualizations are integrated to enhance the interpretability of the model, offering valuable insights into its decision-making process.This innovative framework not only boosts classification accuracy but also sets a new benchmark in CXR-based disease diagnosis.
