Transverse slices of a T2* GE (a,b) and a fat-saturated post-contrast T1 SE (c,d) sequence at the level of the ulnar styloid process (left) and the pisiform bone (right). The ulnar artery is still patent in the proximal sections (arrowheads). Further distally, it shows intra-luminal signal void surrounded by a halo of contrast enhancement (arrows).
