The primary objective of this study is to investigate the predictive value of High-resolution magnetic resonance vessel wall imaging for future stroke occurrence in patients with moderate to severe intracranial and extracranial artery stenosis. The secondary objective is to explore the predictive value of baseline high-resolution magnetic resonance vessel wall imaging for plaque progression.

Lumen Stenosis Rate
The lumen stenosis rate is calculated using the 3D TOF-MRA measurement of the vertebral-basilar artery's narrowest diameter and the normal diameter at the proximal end. The calculation follows the Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) standard formula: Lumen Stenosis Rate = \[1- (Narrowest Diameter / Normal Diameter at Proximal End)\] × 100%
