High resolution magnetic resonance vessel wall imaging (MRVWI) is now widely used for the risk evaluation of patients with ischemic stroke. The use of MRVWI with and without contrast agent is a diagnostic criterion from expert consensus recommendations. However, patients with renal insufficiency who receive gadolinium-based contrast agents are at risk for developing a debilitating and potentially fatal disease known as nephrogenic systemic fibrosis. The study proposes a method based on adversarial generation network to obtain enhanced MR vessel wall image without using contrast agent. The results show the enhancement effect is consistent with the contrast-enhanced MRVWI images.
