What is rheoencephalography used for?

Cerebral blood flow chart is also called transcranial Doppler. It uses the principle similar to B-ultrasound to check intracranial blood flow. It is used clinically, especially in outpatient clinics. If the patient shows symptoms of cerebrovascular disease or even headache or dizziness, the patient can be examined. After cerebral blood flow chart examination, it can be found whether the blood flow of the internal carotid artery system and vertebrobasilar artery system of the patient increases or decreases. If the blood flow is increased, it means that there is a stenosis in the blood vessel. If all the blood vessels are increased, it is necessary to look for systemic diseases. If the patient's blood flow shows a slowdown, it is often not very significant. There is also a disease called steal blood syndrome. This is a relatively special type of vascular stenosis. After examination of the cerebral blood flow chart, steal blood syndrome can be found. If an abnormality is detected on the rheogram, CTA or MRI may be further performed to observe the patient's vascular stenosis, and surgery may even be considered.
