 The intracranial internal carotid arteries demonstrate no significant stenosis. The middle and anterior cerebral arteries are also patent. The vertebral arteries, basilar artery, and posterior cerebral arteries also are patent with no significant stenosis. Right vertebral artery is dominant. Left vertebral artery terminates as the left posterior inferior cerebellar artery. Right posterior communicating artery and anterior communicating artery are patent. Left posterior communicating artery is not well seen and may be diminutive. No evidence of aneurysms or vascular malformations within the limits of mild motion degradation.
No significant stenosis in the intracranial vasculature.
