Intracranial artery disease (IAD) is an important but often overlooked contributor to the onset of stroke. Besides the commonly inspected luminal stenosis, intraplaque hemorrhage (IPH), as indicated by studies based on carotid artery lesions, has also been associated with increased lesion progression rate and the incidence rate of clinical events. In this study, we will validate a newly optimized Simultaneous Non-contrast Angiography and intraPlaque hemorrhage (SNAP) technique suitable for joint stenosis and IPH lesion detection for IAD patients.
