Transcranial Doppler is done for cerebral hypoperfusion, but a cranial CT may also be needed to rule out other pathologies.
Insufficient cerebral blood supply is most often caused by narrowing or blockage of the channels through which blood enters the brain, and patients may experience symptoms such as dizziness, headaches, and memory loss.
When insufficient cerebral blood supply is suspected, transcranial Doppler ultrasound may be performed to examine the carotid arteries, vertebral arteries, and other large blood vessels in the brain to check for atherosclerosis and stenosis. If there is any abnormality, further examination such as CTA of head and neck vessels can be performed to clarify the vascular condition. It is also necessary to improve the cranial CT scanning or MRI examination to exclude whether there are organic lesions in the brain.
If the patient has dizziness, headache, memory loss and other symptoms related to cerebral blood supply insufficiency, please follow the doctor’s instructions to improve the relevant examinations, to clarify the cause of the disease, and timely treatment, so as to avoid delaying the condition.
