Compared to luminal angiographic techniques, high resolution magnetic resonance imaging is more helpful to the diagnosis and differential diagnosis the dissection from other vascular pathologies such as atherosclerosis or aneurysm. In this study, we present results obtained with vessel wall imaging to evaluate the characteristics of spontaneous intracranial artery dissection. We divided patients into two groups according to CE-MRA, and compared the characteristics of high resolution magnetic resonance imaging between two groups. The results of our study may be helpful to understand the lumen and wall change of different type of spontaneous intracranial artery dissection shown on luminal angiographic techniques.
