A central vein running through a lesion visible in the three planes (zoomed-in boxes) in a 3D FLAIR* obtained combining FLAIR and T2*-EPI acquisitions at 3 T. Resampling was applied to the magnified images for visualization purposes. FLAIR, T2*-EPI and FLAIR* are the MRI contrasts that have been used by ML approaches for CVS detection. Refer to the supplementary material for additional examples of the CVS on different susceptibility-weighted imaging sequences.
