Brain Tumor Classifications Using MRI Scans with Deep Learning
Anastasija Stefanovska and Hristijan Gjoreski Abstract: This paper focuses on the detection and classification of brain tumors using MRI images and Deep Learning methods. The dataset consists of 7,023 MRI scans representing healthy brains and brains with glioma, meningioma, or pituitary tumors. We developed and evaluated Convolutional Neural Network (CNN) models of varying depth, combined with preprocessing techniques such as image resizing, limited augmentation, and validation set allocation to prevent overfitting. The study demonstrates that CNN-based approaches can achieve high accuracy in tumor classification, with the best model reaching an overall accuracy of 98.5%. Results show that the greatest misclassification occurred between glioma and meningioma, reflecting their similar MRI appearance. Further analysis confirms that these tumor types share overlapping visual characteristics, making them more challenging to separate. Overall, the findings highlight that well-designed architectures and carefully controlled preprocessing can significantly enhance automated brain tumor detection, offering valuable support for radiologists and contributing to more efficient, consistent, and reliable diagnostic workflows.
