Area of Science:

• Medical Imaging
• Artificial Intelligence
• Oncology

Background:

• Brain tumors (BT) present a significant health risk, necessitating accurate classification for effective treatment.
• Magnetic Resonance Imaging (MRI) is crucial for visualizing brain tumors, but DL models for classification often lack accuracy.
• Existing deep learning models for brain tumor diagnosis exhibit limitations in precision, potentially leading to misdiagnosis.

Purpose of the Study:

• To introduce a novel methodology, RPGFR2U++MASO(3)EGNN-SGA, for enhanced brain tumor classification.
• To improve the accuracy and reliability of brain tumor diagnosis using Contrast-Enhanced MRI (CE-MRI) and BRATS 2018 datasets.
• To address the limitations of current deep learning models in brain tumor classification.

Main Methods:

• Utilized the Iterative Robust Peak-Aware Guided Filter (RPAGF) for noise reduction and feature preservation in MRI data.
• Employed Multilayer Edge Attention (MEA-Net) for sophisticated feature extraction and refinement.
• Applied SO(3)-equivariant Graph Neural Networks for precise graph-based feature analysis.

Main Results:

• The proposed RPGFR2U++MASO(3)EGNN-SGA achieved high classification accuracy: 99.6% on the BRATS 2018 dataset and 99.7% on the CE-MRI dataset.
• Demonstrated superior performance compared to existing methods in brain tumor identification and classification.
• The methodology showed significant potential for improving diagnostic outcomes in oncology.

Conclusions:

• The RPGFR2U++MASO(3)EGNN-SGA methodology offers a robust and highly accurate approach for brain tumor classification.
• This advanced technique shows considerable promise for future breakthroughs in the early detection and precise classification of brain tumors.
• The study highlights the potential of integrating advanced image processing and deep learning for improved cancer diagnosis.
