Abdominal CT datasets have dozens to a couple thousand tumor masks. In contrast, hospitals and new public datasets have tens/hundreds of thousands of tumor CTs with radiology reports. Thus, we ask: how can radiology reports improve tumor segmentation?
We present R-Super, a training strategy that transforms radiology reports (text) into direct (per-voxel) supervision for tumor segmentation AI. Before training, we use LLM to extract tumor information from radiology reports. Then, R-Super introduces new loss functions (Volume Loss & Ball Loss), which use this extracted information to teach the AI to segment tumors that are coherent with reports, in terms of tumor count, diameters, and locations. R-Super can train AI on large-scale CT-Report datasets (e.g., Merlin) plus small or large CT-Mask datasets (e.g., AbdomenAtlas, PanTS). In comparison to traditional training with masks only, using R-Super to train with masks and reports improved the performance of tumor segmentation AI by up to +16% in sensitivity, F1, AUC, DSC and NSD.

[!NOTE]
Extension: Learning from 100,000 CT Scans and Reports, to Segment 7 Understudied Tumor Types
We have assembled more than 100,000 CT-Report pairs and trained R-Super to detect 7 tumor types missing from public CT-Mask datasets. Our preprint is available here.
