Reduce, Then Encode: Multiscale Volumetric Reduction for 2D Foundation Models in Brain MRI

Pretrained 2D foundation models offer a practical alternative to dedicated 3D pretraining for brain structural magnetic resonance imaging (sMRI), but their use on volumetric data requires bridging the mismatch between a 2D encoder and a 3D volume input. Existing methods typically encode slices independently and integra...

Toward Multimodal AI for Dementia: A Challenge-Driven Survey of LLMs and VLMs

Dementia affects over 57 million people worldwide and places an immense burden on informal caregivers, yet current AI tools remain largely fragmented across isolated tasks and modalities. Recent large language models (LLMs) and vision-language models (VLMs) offer promising capabilities for dementia support, but adaptin...
