Cerebral angiography

Cerebral angiography is a new technique of X-ray examination widely used in clinical practice since the 1990s. It first selects an access artery, usually the right femoral artery, and places an arterial sheath through the right femoral artery. Different catheters are used. Under the guidance of the guide wire, the artery to be displayed is selected and an iodine-containing contrast agent is injected. The trajectory of the blood vessels passing by the contrast agent is continuously photographed, and the digital subtraction angiography (DSA) of the cerebral blood vessels is imaged by computer-assisted imaging.
