Abstract: Highlights•Self-supervised contrastive learning on pairs of 3D brain CTA image and radiologist’s report.•Generalizable on multiple acute stroke management tasks on data from other hospitals.•Robust performance with reduced amount of training data in fine tuning.•Combining self-supervised learning with linear probing improves generalizability.
