Abstract
What's the motivation: -Medical vision foundation models (VFMs) should help to better clinical decision making -In medicine, prognosis can help long-term treatment planning, in addition to diagnosis Clinical use case: Use CT scan to predict probability of cardiomegaly (enlarged heart) in the next 12 month E.g. VFMs should learn to identify biomarkers through self-supervised pretraining ✅Ideal Use GradCAM to probe models * Example from paper CT input ❌ Not ideal Why fail?
