A three-dimensional dark-blood cine magnetic resonance imaging pulse sequence capable of displaying the human arterial wall is described. The method is applied to the carotid arteries and demonstrates the ability to display the arterial wall and its motion with fine temporal resolution and submillimeter spatial resolution over the cardiac cycle.
