 Examination is mildly motion degraded. There are mild scattered areas of narrowing in the intracranial vasculature including the right supraclinoid internal carotid artery, right distal vertebral artery, as well as mild to moderate stenosis involving the mid basilar artery. The intracranial internal carotid, anterior, and middle cerebral arteries demonstrate no high-grade stenosis. Vertebral, basilar, and posterior cerebral arteries also demonstrate no high-grade stenosis. Left posterior cerebral artery is fetal in origin. No evidence of aneurysms or vascular malformations.
Mildly motion degraded exam without evidence of high-grade stenosis or occlusion in the intracranial vasculature. There are mild scattered areas of stenoses described above with artifact limiting assessment.
