∙ 13y agoThe brain can be examined in several ways. Anatomical cross sections can be made, post-mortem, in order to characgterize an illness or determine cause of death. CT and MRI scans of the brain can assess disease processes. PET scans of the brain can track blood flow to different regions of the brain, and assess potential areas of hypoperfusion (or suboptimal oxygenation in certain portions of the brain).
