The anterior cerebral artery supplies most of the superior-medial parietal lobes and portions of the frontal lobes with fresh blood. Blood supply to the brain is essential to its functionality, and a ...

Anterior Cerebral Artery Infarction. Axial CT scans. Note the metal fragment (bright signal) near the midline (left upper image). In the remaining scans, note the hypodensity in the distribution of ...

Panel A shows a noncontrast computed tomographic (CT) scan of the head (transverse section) revealing slight hypodensity in the left insular cortex (arrow). Panel B shows a CT angiogram (transverse ...

Transcatheter aortic-valve replacement (TAVR) for the treatment of aortic stenosis can lead to embolization of debris. Capture of debris by devices that provide cerebral embolic protection (CEP) may ...

The posterior communicating artery (PCOM) connects to the internal carotid and helps provide blood supply to the brain. PCOM aneurysms make up about 25% of all intracranial aneurysms. They are more ...
