High resolution cine-MRI was applied for examining aortic valve function and atherosclerotic plaque accumulation in the valves in mice on a high fat diet. The end systolic images of the aortic valves of these mice showed clear signs of atherosclerotic fat accumulation and dysfunction of the valves. This implies that the cine-MRI method provides a noninvasive tool for monitoring atherosclerotic plaques in the mouse aortic valves.
