High-resolution black-blood vessel wall imaging optimized with robust flow suppression offers reproducible, reliable, and non-invasive longitudinal evaluation of flow diversion treated aneurysms, with superior overall classification accuracy relative to conventional TOF or dynamic MRA. Aneurysm and parent vessel enhancement may persist even after angiographic occlusion during the healing phase of obliterated aneurysm.
