Ischemic Stroke Classification Using VGG-16 Convolutional Neural Networks: A Study on Moroccan MRI Scans

Abstract

This study presents a comprehensive exploration of deep learning models for precise brain ischemic stroke classification using medical data from Morocco. Following the OSEMN approach, our methodology leverages transfer learning with the VGG-16 architecture and employs data augmentation techniques to enhance model performance. Our developed model achieved a remarkable validation accuracy of 90%, surpassing alternative state-of-theart models (ResNet50: 87.0%, InceptionV3: 82.0%, VGG-19: 81.0%). Notably, all models were rigorously evaluated on the same meticulously curated dataset, ensuring fair and consistent comparisons. The investigation underscores VGG-16’s superior performance in distinguishing stroke cases, highlighting its potential as a robust tool for accurate diagnosis. Comparative analyses among popular deep learning architectures not only demonstrate our model’s efficacy but also emphasize the importance of selecting the right architecture for medical image classification tasks. These findings contribute to the growing evidence supporting advanced deep learning techniques in medical imaging. Achieving a validation accuracy of 90%, our model holds significant promise for real-world healthcare applications, showcasing the critical role of cutting-edge technologies in advancing diagnostic accuracy and the transformative potential of deep learning in the medical field.

Automated Ischemic Stroke Classification from MRI Scans: Using a Vision Transformer Approach

“…The ViT-b16 model demonstrated exceptional performance in classifying ischemic stroke cases from Moroccan MRI scans, achieving an impressive accuracy of 97.59% on the evaluation dataset. This result surpasses the accuracy obtained in a previous study that utilized the VGG-16 model on the same dataset [23]. For a comprehensive comparison, we present the accuracy metrics of all models, including ViT-b16 and the baseline models (VGG-16, ResNet50, InceptionV3, and VGG-19), in Table 4 below.…”
