Brain MRI is normal. Do I need an angiogram?

Angiography is a non-invasive examination that can show the shape, structure and blood flow of cerebral vessels and help to detect cerebral vascular stenosis, aneurysms, cerebral vascular malformations, etc.

If there are symptoms such as headache, dizziness, blurred vision, unclear speech, weakness of limbs, or risk factors for cerebrovascular diseases, such as hypertension, diabetes, hyperlipidemia, smoking, etc.

, you should seek medical attention promptly and conduct relevant examinations and treatment according to the doctor's advice.
