CT angiography of the head
Author:

Planning
Alternative investigations
Magnetic resonance angiography of the head is indicated in:
- Less emergent situations, since it is generally less readily available.
- Contraindications to intravenous contrast, since it can visualize cerebral vessels without it.
Constructions
Aneurysms are more readily visualized by thick slices such as 15mm, but thin slices such as 1.2 mm still need to be observed if there may be a focal occlusion or stenosis.
