High-resolution magnetic resonance (HR-MR) imaging in intracranial atherosclerotic disease poses a greater challenge in the neurologic fields. Because a high in-plane resolution and a high signal-to-noise ratio are required for vessel wall imaging. HR-MR can depict the morphologies of atherosclerotic plaques, arterial walls, and surrounding structures in the intracranial and cervical carotid arteries. HR-MR also can be observed with traditional luminal evaluation. Differentiating vulnerable from stable plaques and characterizing atherosclerotic plaques are vital parts of the early diagnosis, prevention, and treatment of stroke with atherosclerosis. HR-MR is the most important and popular vessel wall imaging technique for directly evaluating the vascular wall and intracranial artery disease. Intracranial artery atherosclerosis, dissection, moyamoya disease, vasculitis, and reversible cerebral vasoconstriction syndrome also can be diagnosed and differentiated by using HR-MR. Here, we review the radiologic features of intracranial artery disease and vertebral artery dissection on HR-MR.
