Cambridge's SAM-Brain3D surpasses existing methods for early brain disease detection
lawrennd · x · 2026-10-01
Zhongying Deng, postdoc at Cambridge's Accelerate Programme, developed SAM-Brain3D, a brain foundation model that outperforms current methods for detecting brain diseases like Alzheimer's. Supported by the Accelerate-C2D3 funding call.
- Brain diagnosis requires integrating heterogeneous data from MRI, PET, genetic profiles and cognitive scores; existing brain foundation models are limited by task/data homogeneity and poor generalization
- SAM-Brain3D pairs with a lightweight Hypergraph Dynamic Adapter (HyDA) for multi-task performance: tumor segmentation, disease classification and more
- Goal: predict diagnoses from baseline visit data to enable earlier treatment; Alzheimer's accounts for 60-80% of dementia cases
