CT dense MCA
This is a head CT from a person who has recently begun to show symptoms of a severe left MCA stroke. As CT does not show tissue changes in the first several hours, the brain parenchyma appears normal even though it is infarcting. What can be seen sometimes,...

CTA Right M1 occlusion
A CT angiogram of the vessels in the brain. The vessels for the left side of the brain are on the right side of the image, and the ones for the right side of the brain are on the left side of the image. Note how the right middle cerebral artery (MCA) stops...

MRI T2 MCA ACA normal
A T2-weighted MRI image of a normal brain. In this slice, both middle cerebral arteries, both anterior cerebral arteries, and the anterior communicating arteries can be seen. Move your mouse pointer over this image to see the arteries highlighted in green.

CT Circle of willis
Both MCAs and both PCAs are visible in this CT of normal brain. Move your mouse pointer over the image to see the vessels highlighted in green.

MRI acute right MCA stroke
This shows an MRI from someone who has had an acute right middle cerebral artery infarction. The image on the left is a diffusion-weighted MRI (DWI). The area in white shows the acute infarction. The image on the right shows the ADC map corresponding to the same image...

CT left PCA stroke
A non-contrasted head CT showing a recent left posterior cerebral artery (PCA) infarction.

MRI DWI left ACA stroke
A diffusion-weighted MRI image showing an acute left anterior cerebral artery (ACA) infarction.

Left MCA stroke, whole brain
This is a photograph of whole brain, showing a left MCA stroke.

PICA stroke, whole brain photo
A photograph of whole brain showing an infarction in the right posterior inferior cerebellar artery (PICA) distribution.

ACA infarct sagittal
A photograph of the medial surface of a brain cut through the midsagittal plane. At some point during this person's life, he or she suffered a stroke in the distribution of the left anterior cerebral artery (ACA)

PCA stroke, medial surface of brain
This is a gross brain, bisected at the mid-sagittal plane. We are looking at the medial surface of the left hemisphere. The dark region at the posterior portion of the brain represents infarcted tissue. This individual suffered a left posterior cerebral artery (PCA) infarction...
