Retrospective Examination of Vessel Wall Imaging in Intracranial Arterial Structures in Cases with Acute or Chronic Cerebral Ischemia

Magnetic resonance angiography (MRA) is a good screening tool with minimal invasiveness and no ionizing radiation, and the vessel wall can also be evaluated with additional sequences.High-resolution magnetic resonance imaging (HR-MRI) has been introduced for direct assessment of the vessel wall beyond only luminal information, such as the severity of stenosis in the vessel walls (5).HR-MRI can reveal characteristic radiological features associated with vessel wall pathologies in diseases such as intracranial artery involvement, such as atherosclerosis, dissection, Moyamoya disease, and vasculitis (6,7).Black-blood HR-MRI is recently used in the evaluation of cerebrovascular diseases (2).Contrast-
