Transcranial Doppler Ultrasonography

Transcranial Doppler Ultrasonography (TCD) is a non-invasive ultrasound technique used to measure blood flow in the brain’s main arteries. Using sound waves, it detects and analyzes the speed and pattern of blood moving through these vessels. This helps doctors assess brain circulation, identify blood clots or narrowing, and monitor conditions like strokes or aneurysms. The procedure is quick, painless, and safe, providing valuable information about cerebral blood flow without the need for surgery or radiation.
