Background technique

Cerebral angiography is a X-ray examination technique that has been widely used in clinic since 1990. It first selects an access artery, usually the right femoral artery, and places an arterial sheath through the right femoral artery. Different catheters were selected, and under the guidance of the guide wire, the artery to be displayed was selected, and iodine-containing contrast agent was injected. Continuous imaging of the blood vessel trajectory through which the contrast agent passes, and digital subtraction angiography (DSA) of the cerebral blood vessels through computer-aided imaging, which can specifically understand the morphological changes of blood vessels, such as changes in course, distribution, displacement, thickness and circulation time. Wait. It is of special value for the diagnosis of cerebrovascular disease to finally determine whether the lesion is the blood vessel itself or whether the lesions in other parts of the brain cause vascular changes.

However, when performing cerebral angiography on a patient, the patient needs to lie flat on the imaging bed with the head fixed.
