 MRI Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are bilateral prominent perivascular spaces in the basal ganglia. Minimal scattered periventricular and subcortical white matter T2 hyperintensity is nonspecific. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.MRA Brain: 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. No evidence of aneurysms or vascular malformations.MRA Neck: There is a separate origin of the left subclavian artery, left common carotid artery, and brachiocephalic artery from the arch. The common carotid arteries and cervical internal carotid arteries are normal in course and caliber. There is a retropharyngeal right internal carotid artery. Both vertebral artery origins are patent. There is no evidence of stenosis or occlusion. There appears to be a right thyroid nodule that measures up to 6 mm.
1.No evidence of an acute infarct.2.Minimal scattered likely chronic small vessel ischemic disease.3.No high-grade stenosis involving the intracranial or neck arteries.4.Apparent right thyroid nodule that measures up to 6 mm. A thyroid ultrasound may be useful for further evaluation.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
