Deep MultiModal MRI Fusion Model for Brain Tumor Grading
Glioma is a type of brain tumor that occurs in glial cells and is classified into two types: high grade glioma(HGG) with a poor prognosis and low grade glioma(LGG).
We developed a Multimodal & Multiview (MmMv)
model that applied input-level fusion to MRI of four modalities (T1, T1Gd, T2, T2-FLAIR) for glioma grading.
