Representative 3D intracranial vessel wall MR images acquired in two scans from a 55-year-old male healthy subjects and reformatted cross-sections (upper left in the yellow box) for each designated arterial segment in the location indicated by the dashed lines. Both scans provide exquisite vessel wall depiction for the five designated arterial segments: the distal basilar artery, distal vertebral artery (VA (V4)), the distal internal carotid artery (ICA) supraclinoid segment (C4), the middle cerebral artery (MCA) M1 segment right after the trifurcation, and the anterior cerebral artery (ACA) A1 segments
