Background:

Conventional radiology for glioma lacks quantitative assessment of tumor heterogeneity.
Deep learning models address complex multidimensional data through cross-modal feature fusion.
Transformer-3D CNN hybrid models with attention mechanisms are key for advanced analysis.

Purpose of the Study:

To review recent advances in multimodal MRI and deep learning fusion for glioma diagnosis and treatment.
To clarify technical development trajectories and address core bottlenecks in clinical translation.
To provide a theoretical basis for integrating these technologies into clinical practice.

Main Methods:

Utilizing multimodal MRI data combined with deep learning techniques, including Transformer-3D CNN hybrid models.
Employing cross-modal attention mechanisms for feature fusion.
Analyzing data for segmentation accuracy, molecular marker prediction, and clinical outcome prediction.

Main Results:

Achieved enhanced glioma segmentation accuracy (Dice coefficient of 0.92).
Enabled noninvasive prediction of IDH mutation and uncovered links to EGFR/PI3K-AKT pathways.
Predicted glioma recurrence 3-6 months earlier and identified primary lesions of metastatic brain tumors with 87.5% accuracy.

Conclusions:

Multimodal MRI and deep learning offer a data-driven paradigm shift for glioma care.
Challenges like data heterogeneity and model interpretability require standardized protocols for clinical translation.
Future work involves integrating multi-omics data and developing real-time decision systems for personalized glioma management.
