BrainTRACE contains 7,273 scored VQA instances derived from 1,778 longitudinal patients and ~29k 3D MRI volumes. It evaluates five levels of clinical reasoning across four evidence demands: longitudinal comparison, multi-sequence integration, volumetric spatial evidence, and report-grounded references.
The benchmark uses exact closed-form scoring for specific questions and factual audit scoring for open-ended answers. Evaluation of 20 VLM configurations reveals a significant gap in composing grounded longitudinal interpretations, with the best case success rate at only 1.4%.
