Brain metastasis: A cross-section through a patient's brain after administration of intravenous contrast shows the contrast accumulating in the periphery of a cancerous deposit that has traveled to the brain, giving a characteristic ring-enhancing appearance.

A CT cross-section through a patient's brain shows an intraparenchymal hemorrhage (arrow), meaning blood within the substance of the brain. Also shown is a subarachnoid hemorrhage (arrowhead), or blood surrounding the surface of the brain; and edema (asterisk), or swelling of the brain.

Bleeding within the brain (a hemorrhagic stroke, arrows). The blood is white, and there is slightly darker than normal areas surrounding this, due to local brain swelling (edema).
G = normal brain gray matter
W = normal brain white matter (darker on CT scans than gray matter)
Arrows = blood
