Brain aneurysm treatment. Coloured angiogram (blood vessel X-ray), in frontal view, of the head of a 49-year-old patient undergoing treatment for a brain aneurysm. A brain aneurysm is a dangerous swelling in a brain blood vessel. This treatment involves inserting metallic coils (black, centre) into the aneurysm. The X-ray is used to show the position of the coils, placed by electromagnetic controls, and a contrast medium shows the blood vessels (red). The coils cause clotting of blood in the aneurysm, and eventually the blood vessel reforms its wall. This technique is an alternative to direct surgery. The blood vessel being treated here is the basilar artery that supplies the base of the brain.
Bat skull, X-ray: note the developed organs of the inner ear used for echolocation; on either side of the base of this bat skull are large coiled cochlea, the organs of hearing.

This is a sterogram, to be viewed in crossview technique: cross your eyes, relax your vision until there are three images, then focus on the center image.
Stereoscopic cross view photos can be viewed in three dimension (3D) without special glasses. Most people can learn how to view a cross view photo in just a few minutes:

Stroke. Coloured angiogram of the brain of a 48 year old patient after a stroke. There are fewer blood vessels visible compared to normal. This is due to a blocked middle cerebral artery causing areas of ischaemia to parts of the brain. Strokes can be instantly fatal, or may pass unnoticed. Symptoms can include muscle weakness, behavioural changes or paralysis.
