Posterior Cerebral Artery (PCA) Infarction: Diffusion-weighted MRIs.Note the bright signal in the distribution of the right posterior cerebral artery. This syndrome is most often caused by a cardiac ...

Posterior Cerebral Artery (PCA) Infarction: Flair axial MRIs. Note the bright signal in the distribution of the right posterior cerebral artery. If one looks closely, one can also see a small infarct ...

Figure 1. Anterior and posterior cerebral circulations are illustrated using images from a cerebral angiographic series. On the left is a frontal view from a right common carotid artery injection.

When retrograde injection of the human brachial artery is coupled with high-speed roentgenography it provides artifact-free data regarding the complete cervical-cerebral circuit. 12 It has also ...

Symptoms and signs of moyamoya can be attributed to changes in flow resulting from stenosis of the internal carotid artery. Broadly speaking, there are two major etiologic categories of symptoms ...

The cerebral vasculature is a complex network comprising multiple arteries, most of which are deep and widely distributed inside the brain. To examine this entire network in 3D, the patch performs ...

Left: CT angiogram showing an aneurysm of 2 mm maximum diameter on the left posterior cerebral artery (arrow). Right: volume-rendered 3D reconstruction image. The aneurysm was missed in the initial ...

image: The network of arteries supplying blood flow to the brain is more likely to be incomplete in people who suffer migraine, a new study by researchers in the Perelman School of Medicine at the ...

As compared with aneurysms located in the middle cerebral arteries, those located in the posterior communicating arteries were more likely to rupture (HR, 1.90; 95% CI, 1.12 - 3.21), as were those ...

The functional roles of the nitrergic nerves innervating the monkey cerebral artery were evaluated in a tension-response study examining isolated arteries in vitro and cerebral angiography in vivo.

In a study of 170 people from three groups - a control group with no headaches, those who had migraine with aura, and those who had migraine without aura - the team found that an incomplete circle ...
