TCD (Transcranial Doppler Sonography)

TCD is a diagnostic procedure using ultrasound to assess the arteries located at the base of the brain. The purpose of this test is to detect any narrowing or blockage in these arteries that may decrease or stop the flow of blood to the brain.

A small hand-held, wand-like probe covered with a conductive gel will be placed and held at various areas on your head, usually at each temple, over each eye, and at the base of the skull. This enables us to image the blood flow in the arteries and to record the flow in each artery. The procedure should take 20 to 60 minutes and is painless. You may resume normal activity immediately following the test.
