Transcranial Doppler (TCD) ultrasound provides rapid, noninvasive, real-time measures of cerebrovascular function. TCD can be used to measure flow velocity in the basal arteries of the brain to assess relative changes in flow, diagnose focal vascular stenosis, or to detect embolic signals within these arteries. Transcranial doppler ultrasound (TCD) is a diagnostic test. It measures blood flow to and within the brain.

Transcranial Doppler “Stethoscope to the brain” TCD is a non-invasive ultrasound method used to examine the blood circulation within the brain. This is similair to the well-known carotid ultrasound study that is used to exam the arteries in the neck Transcranial Doppler Ultrasound. Doppler ultrasound scanning measures blood flowing through the carotid arteries or the arteries at the base of the brain. This test assesses the risk of stroke. This technique shows different speeds of blood flow in different colors on a computer screen. It also can show blocked or reduced blood flow in the arteries Transcranial Doppler Ultrasound Device (TCD) - Non-Invasive Diagnostic Tool For Ultrasound Imaging of Head & Neck.

Ultrasound imaging of the head uses sound waves to produce pictures of the brain and cerebrospinal fluid. It is most commonly performed on infants, whose skulls have not completely formed. A transcranial Doppler ultrasound evaluates blood flow in the brain's major arteries. Ultrasound is safe, noninvasive, and does not use ionizing radiation.
Your doctor has recommended that you have this test to determine the amount of blood flow to certain areas of your brain. Here at Regional Neurology we have specialized technician to perform this procedure. Transcranial Doppler ultrasonography (US) is a noninvasive technique that allows accurate and sensitive evaluation of the cerebral vessels for vasospasm without requiring the use of a contrast medium, exposure of the patient to ionizing radiation, or transport of the patient out of the intensive care unit (6 – 8). Select the Transcranial Doppler model that best meets your needs! Dolphin/ 4D The next generation Transcranial Doppler (TCD) All-In-One system that will exceed everything you know and expect from a TCD system.
Transcranial Doppler (TCD) ultrasonography is a noninvasive ultrasound (US) study, which was introduced in clinical practice in 1982, since then it has been extensively applied on both outpatient and inpatient settings.
