Transcranial Doppler (TCD)


Transcranial doppler (TCD) ultrasound is a 15 minute non invasive and painless test that uses sound waves to measure the rate and direction of blood flow in the arteries that feed the brain. It is used to detect medical problems that affect blood flow in the brain. It can detect stroke caused by blood clots, narrowed sections of blood vessels, vasospasm due to a subarachnoid hemorrhage, tiny blood clots and more.
