The buttons below will show the location of the vessels seen on this image with IV contrast. The anterior cerebral arteries are not really seen well, so they are shown as dotted lines. The area circled on the prior image was the top of the petrous bone.

Normal liquid flowing blood in a vessel is just a bit more dense (whiter) than brain tissue, but the difference can be subtle. The basilar artery is present on this noncontrast image, and you can use the button below to show its location.
