ANSWERS AND EXPLANATIONS
A) CT of a stroke in the territory of right PCA
This answer is incorrect.
This is an MRI diffusion weighted image. The bright area represents diffusion restriction, which can be seen in acute stroke. The area of diffusion restriction corresponds to the right posterior cerebral artery (PCA) territory. (

B) MRI diffusion-weighted image of a stroke in the territory of right PICA
This answer is incorrect.
This is an MRI diffusion weighted image. The bright area represents diffusion restriction, which can be seen in acute stroke. The area of diffusion restriction corresponds to the right posterior cerebral artery (PCA) territory.
The posterior inferior cerebellar artery (PICA) does not supply the territory where this stroke occurred.

E) MRI diffusion-weighted image of a stroke in the territory of left SCA
This answer is incorrect.
This is an MRI diffusion weighted image. The bright area represents diffusion restriction, which can be seen in acute stroke. The area of diffusion restriction corresponds to the right posterior cerebral artery (PCA) territory. The stroke in this image is on the right, not the left.
The superior cerebellar artery (SCA) does not supply the territory where this stroke occurred.
