  • Abstract:
  • Accurate identification of brain tumors from magnetic resonance imaging (MRI) scans plays a significant role in supporting clinical diagnosis and treatment planning. Manual examination of large volumes of MRI images is time-consuming and may be influenced by inter-observer variability, creating a need for reliable computer-aided diagnostic systems. This study presents a deep learning-based framework for automated brain tumor classification using MRI images. The proposed work investigates the performance of a custom Convolutional Neural Network (CNN) and three transfer learning models, namely ResNet18, VGG16, and ResNet50, for the classification of four categories: glioma, meningioma, pituitary tumor, and no tumor. Image preprocessing techniques, including resizing, normalization, and data augmentation, were applied to improve model robustness and generalization. To enhance transparency in decision-making, Gradient-weighted Class Activation Mapping (Grad-CAM) was incorporated to visualize the image regions that contributed most to the model predictions. Experimental evaluation demonstrated that ResNet18 achieved superior performance compared to the other models, obtaining a test accuracy of 94.39%. The proposed framework not only provides accurate classification results but also offers visual interpretability, making it more suitable for medical imaging applications. Furthermore, a user-friendly Gradio-based interface was developed to facilitate real-time prediction of brain tumor categories from MRI scans. The findings indicate that combining transfer learning with explainable artificial intelligence can contribute to the development of effective and trustworthy computer-aided diagnostic systems for brain tumor analysis.
