What issues can be detected by transcranial Doppler ultrasound?

Transcranial Doppler ultrasound is a non-invasive diagnostic method capable of detecting various cerebrovascular disease-related issues, including intracranial vascular stenosis or occlusion, cerebral vasospasm, abnormal cerebral hemodynamics, intracranial vascular malformations, and cerebral aneurysms. If there are any concerns or further diagnosis is needed, timely medical consultation is recommended. Detailed explanations are as follows:

1. Intracranial Vascular Stenosis or Occlusion: Transcranial Doppler ultrasound can accurately measure cerebral blood flow velocity to detect whether there is arterial stenosis or occlusion, which is beneficial for the prevention and treatment of stroke.

2. Cerebral Vasospasm: In conditions such as subarachnoid hemorrhage, cerebral vessels may experience spasms that lead to cerebral ischemia. Transcranial Doppler ultrasound can monitor vasospasm in real time, providing a basis for clinical treatment.

3. Abnormal Cerebral Hemodynamics: By analyzing blood flow velocity and waveform, transcranial Doppler ultrasound can assess cerebral hemodynamic status and detect abnormalities such as those caused by cerebral arteriosclerosis or hypertension.

4. Intracranial Vascular Malformations: Transcranial Doppler ultrasound can display abnormal blood flow signals, assisting physicians in diagnosing intracranial vascular malformations such as arteriovenous malformations and cavernous hemangiomas.

5. Cerebral Aneurysms: Transcranial Doppler ultrasound can detect the presence of aneurysms—localized dilations of the vessel wall—in cerebral vessels, helping to prevent severe complications such as subarachnoid hemorrhage caused by aneurysm rupture.

It is recommended to maintain a healthy lifestyle with adequate sleep, improved dietary habits, and physical well-being to support overall health.
