Intracranial arterial plaque checking blood test examination, ultrasonic examination, cerebral angiography examination, etc. 1. Blood test examination: Blood test examination mainly observes the values of blood lipids and blood sugar of patients, and adjusts the treatment according to the results of the test. Hyperglycemia and hyperlipidemia are one of the main causes of intracranial arterial plaque. 2. Ultrasonography: Ultrasonography is a non-invasive way of examination, through which the presence or absence of plaque and the blood flow rate of blood vessels can be detected. 3. Cerebral angiography: It includes MRA, CTA and DSA. Cerebral angiography can more accurately observe whether the patient’s cerebral blood vessels are narrowed. Patients suspected of having intracranial arterial plaque should consult the doctor in time, standardize the examination and treatment to avoid delaying the condition.
