Title
MRA of the Brain
Clinical History
Patient-specific — populated from user input at report time. Shows "None" if not provided.
Comparison
No prior studies available for comparison.
Technique
MRA of the head was performed using 3D time-of-flight technique without intravenous gadolinium. Multiple 3D MIP reconstructions were obtained.
Findings
Evaluation of the intracranial vasculature demonstrates normal flow-related enhancement without evidence of hemodynamically significant stenosis, occlusion, or aneurysm.
Internal Carotid Arteries:
The bilateral internal carotid arteries are patent.
Anterior Cerebral Arteries:
The anterior cerebral arteries appear unremarkable bilaterally.
Middle Cerebral Arteries:
The middle cerebral arteries appear unremarkable bilaterally.
Anterior Circulation:
No evidence of hemodynamically significant stenosis or occlusion within the anterior circulation.
Posterior Communicating Arteries:
The posterior communicating arteries are patent.
Vertebral Arteries:
The distal aspects of both vertebral arteries appear patent and co-dominant.
Basilar Artery:
The basilar artery appears unremarkable.
Posterior Cerebral Arteries:
The posterior cerebral arteries appear unremarkable bilaterally.
Posterior Circulation:
No evidence of hemodynamically significant stenosis or occlusion within the posterior circulation.
Cerebral Aneurysms:
No definite evidence of cerebral aneurysm is identified.
Circle of Willis:
The circle of Willis is intact without evidence of stenosis, occlusion, or dissection.
Impression
No evidence of hemodynamically significant stenosis, occlusion, dissection, or aneurysm within the visualized vessels of the circle of Willis.
