24-hour stroke and death rate following diagnostic cerebral angiogram

Cerebral angiography is a diagnostic test that uses X-ray to evaluate the blood vessels in the head or neck to assess for blockages or abnormalities. This minimally invasive procedure helps to diagnose and determine the best treatment for certain patients with stroke and other cerebrovascular disease.
