What anatomical structures are well seen with CT  


CT is also an excellent way to view the brain and contents within the skull. None of these can be seen with radiographs.

The image on the left is of the inferior part of the brain, and the image on the right is slightly more superior. Note the low density fluid of the subarachnoid space and lateral ventricles is well differentiated from the varying shades of gray of the arteries supplying the brain, and the brain parenchyma itself. CT also demonstrates the subtle differences in the gray and white matter tracts of the brain parenchyma, which have different compositions and functions. The white matter appears darker than the gray matter.
