Fine-Grained Vision-Language Pretraining with Organ-Conditioned Pattern Tokens for CT Understanding

Computed tomography (CT) vision-language pretraining from paired volumes and radiology reports is a scalable yet challenging task. Existing methods commonly adopt global scan-report contrast, which is scalable but obscures heterogeneous organ evidence. Meanwhile, direct organ-level alignment remains coarse, since the s...

Learning How Much, Not Just What: Cross-Patient Burden Order for CT Vision-Language Pretraining

Volumetric CT vision-language pretraining learns 3D representations from scan-report pairs, but global and anatomy-aware objectives supervise only correspondence: they establish what is present and leave how much unconstrained. Nothing separates a mild from an extensive case of the same finding along a consistent direc...
