The MRI Model Read Across Four Dimensions
Mr3D-VL combines multiple 3D MRI modalities in one language-interactive model for brain-tumor tasks.
Summary
Mr3D-VL combines multiple 3D MRI modalities in one language-interactive model for brain-tumor tasks.
The four-billion-parameter system uses a shared 3D encoder, rotational position encoding across modality and space, and multiresolution feature projection. The authors report a BERTScore of 0.856 for report generation, 0.713 question-answering accuracy and 0.912 multiple-choice accuracy, outperforming tested domain and general models. These are retrospective benchmark results and do not establish prospective clinical safety or diagnostic approval.
