L3 · Multimodal grounding
L3 contains 69 pathology cases, 200 sequence questions, 2,700 structure cards from 100 patients, 400 T-stage cases and 400 N-stage cases.
T400.jsonl and N400.jsonl are the primary stage labels. requests/T400.jsonl and requests/N400.jsonl contain prompts and image paths relative to this L3 directory. Extract images_and_inputs.tar.gz here and the seven MRI shards inside extensions/.
T400 comprises 100 structure-card patients and 300 sequence-group patients; N400 is a disjoint cohort using sequence groups. T-Stg.jsonl provides the labels for the 100-patient anatomical panel used in structure-based diagnostic analyses. Path.jsonl, Seq.jsonl, Struct.jsonl and secondary_labels/ contain the other task references.
See the MRI group guide for sequences, anatomical coverage and model-specific sampling.
