What are the examination items for insufficient cerebral blood supply?
Disease description:
I have been experiencing dizziness, headache, and chest tightness recently, so I plan to go to the hospital for a checkup. I would like to know what medical examinations are available for insufficient cerebral blood supply.

Common diagnostic tests for cerebral ischemia include:
1. Neurological physical examination: The physician will carefully assess the patient's neurological responses, muscle strength, and muscle tone to make an initial evaluation of possible cerebral ischemia.
2. Cranial CT scan: X-rays are used to generate images of the head to check for abnormalities such as hemorrhage or tumors, which can help determine if cerebral ischemia is present.
3. Cerebral angiography: A radiopaque substance is injected into the carotid or femoral artery, followed by X-ray imaging to evaluate the detailed condition of the cerebral blood vessels, which plays an important role in identifying the causes of cerebral ischemia.
4. Transcranial Doppler ultrasound: This technique uses the Doppler effect to assess hemodynamic parameters of major arteries along the circle of Willis, helping to evaluate cerebral blood flow dynamics.
5. Blood tests: These include assessments of blood pressure, lipid levels, blood glucose, complete blood count, and liver and kidney function, which help rule out cerebral ischemia caused by hypoglycemia, anemia, arrhythmia, or myocardial ischemia.
6. Electroencephalogram (EEG): This records the electrical potential differences between brain cell populations via electrodes placed on the scalp and is commonly used as an auxiliary tool in diagnosing brain disorders. Characteristic EEG changes may be observed in cases of cerebral ischemia.
