AI Model Improves Differentiation of Brain Tumor Progression from Radiation Necrosis on MRI
A York University-led study shows a novel AI using advanced MRI can distinguish between progressive brain tumors and radiation necrosis more accurately than human assessment.
Key Details
- 1AI model uses attention-guided deep learning with chemical exchange saturation transfer (CEST) MRI.
- 2Study included over 90 patients with brain metastases treated by stereotactic radiosurgery (SRS).
- 3AI achieved over 85% accuracy in distinguishing tumor progression from necrosis, compared to ~60% for standard MRI and ~70% for advanced MRI alone.
- 4Published December 2025 in International Journal of Radiation Oncology, Biology, Physics.
- 5A crucial clinical challenge as treatment decisions for tumor progression vs necrosis are substantially different.
