Brain Tumor (BT) is a critical neurological disorder that requires early and accurate diagnosis to improve patient survival and treatment outcomes. Recent advancements in deep learning and medical imaging have enabled automated analysis of Magnetic Resonance Imaging (MRI), offering a reliable alternative to manual interpretation, which is often time-consuming and dependent on radiologist expertise. This project proposes a comprehensive deep learning–based framework for multi-class brain tumor classification using MRI images, categorized into four classes: glioma, meningioma, pituitary tumor, and no tumor. The dataset was collected from publicly available medical imaging repositories and preprocessed to enhance image quality and model performance. We conducted an extensive evaluation using multiple state-of-the-art architectures, including EfficientNet variants (B0–B6), VGG16, Xception, and transformer-based models such as MaxViT, to identify the most effective model for tumor classification. Experimental results demonstrate that the proposed framework achieves a high classification accuracy of 97%, indicating strong generalization and robustness across all tumor categories. To ensure clinical interpretability, Explainable AI (XAI) techniques such as Grad-CAM were employed to visualize the regions of interest influencing model predictions. This approach emphasizes the potential of deep learning–based systems as scalable and cost-effective tools for assisting radiologists in early brain tumor detection and classification, enabling timely clinical decision-making. Furthermore, the system can be enhanced by integrating patient clinical data and deploying it as a web-based application for real-time diagnostic support in healthcare environments.
