In this work, we examined the feasibility of registering 4D-flow MRI scans with different scan sequences, and demonstrate how the incorporation of complementary, registered data can enhance characterization of hemodynamic information. Black blood (BB) and 4D-flow magnitude images demonstrated excellent registration between the pre- and post-rotation data sets, with high values of correlation and good overlap of the vessels between head rotation. Joint visualization of aneurysm 4D flow and BB shows accurate lesion depiction only after registration and is a promising technique for the comprehensive evaluation of vascular pathology.
