To give an overview regarding the potential usefulness of vessel wall imaging (VWI) in distinguishing various intracranial vascular diseases, their common imaging features, and potential pitfalls.
VWI provides direct visualization of the vessel wall and allows the discrimination of different diseases such as vasculitis, atherosclerosis, dissection, Moyamoya disease, and reversible cerebral vasoconstriction syndrome. Recent studies showed that concentric and eccentric involvement in the vessel wall, as well as the enhancement pattern were found important for the distinguishing these diseases and evaluating their activity.
Most of the imaging techniques currently used are based on luminal imaging. However, these imaging methods are not adequate to distinguish different diseases that can demonstrate similar radiological findings. VWI is being increasingly used as a noninvasive imaging method to offset this limitation.
介绍血管壁成像（VWI）在鉴别各种颅内血管疾病、其常见影像学特征和潜在陷阱方面的潜在作用。
VWI 可直接显示血管壁，有助于鉴别血管炎、动脉粥样硬化、夹层、烟雾病和可逆性脑血管收缩综合征等不同疾病。最近的研究表明，血管壁的同心和偏心受累以及增强模式对于鉴别这些疾病和评估其活动度非常重要。
目前使用的大多数成像技术都是基于管腔成像。然而，这些成像方法不足以区分可能表现出相似影像学发现的不同疾病。VWI 作为一种非侵入性成像方法，正越来越多地被用于弥补这一局限性。
