Angiography

Angiography is used to visualise the blood vessels. Generally speaking, contrast media are injected into the arteries being examined in order to allow the blood vessel system to be clearly visible. The structures are visualised using imaging methods such as X-rays, MRI or CT scans.

In the brain area, this diagnostic procedure is used in the surgical treatment of aneurysmsangiomas and tumours, for example. Angiography shows the location of neighbouring brain vessels, but also the blood supply to the tumour, which generally comes from the meningeal arteries.

As a result, angiography can be used with microsurgical procedures such as craniotomy to ensure surgical precision, minimising the risk of injuring healthy blood vessels.
