Transcranial Doppler Studies
Transcranial Doppler (TCD) is used for the noninvasive assessment of blood flow to the brain. The noninvasive test uses sound waves to determine the blood flow moving through the arteries to the brain. The study can assist in determining if the arteries are narrowed or blocked. A transducer (probe) placed at the neck or the temple sends an ultrasound signal. The signal is received and transmitted to a microcomputer that calculates how fast the blood is traveling through the artery. A complete TCD study may include assessment of anterior (front) or posterior (back) cerebrovascular circulation. Complete cerebrovascular ultrasound could include both carotid duplex and TCD.
