It measures blood flow to and within the brain. Endarterectomy is a surgical procedure removing plaque material from the lining of an artery. A transcranial Doppler study (TCD) is a safe, painless test that evaluates the blood flow to and in your brain. This test uses high-frequency sound waves that you can’t hear or feel. As the sound waves bounce off blood vessels, information is sent to a computer screen.

This test uses high-frequency sound waves that you can’t hear or feel. As the sound waves bounce off blood vessels, information is sent to a computer screen. Functional transcranial Doppler sonography (fTCD) is a neuroimaging tool for measuring cerebral blood flow velocity changes due to neural activation during cognitive tasks. Functional TCD uses pulse-wave Doppler technology to record blood flow velocities in the anterior, middle, and posterior cerebral arteries.

It is used in the measurement of pressure and velocity in cerebral arteries. The test is quick, accurate and painless. TCD’s are used in the diagnosis of various conditions such as emboli, stenosis, vasospasm, headaches and subarachnoid hemorrhage. Transcranial Doppler (TCD) is a physiological ultrasound test with established safety and efficacy. Although imaging devices may be used to depict intracranial flow superimposed on structural visualization, the end‐result provided by imaging duplex or nonimaging TCD is sampling physiological flow variables through the spectral waveform assessment. Background Transcranial Doppler (TCD) ultrasonogra-phy to demonstrate cerebral circulatory arrest (CCA) is a confirmatory test for brain death (BD).

You may already be familiar with ultrasound technology because of its wide range of uses in diagnosing medical conditions and in monitoring during pregnancy. Transcranial Doppler is ultrasound that is performed at the base of the brain to assess the risk of stroke. How Does It Work? What is a transcranial Doppler study?
transcranial Doppler ultrasound may replace the invasive intra-arterial angiographic examination in many patients with suspected macroangiopathy of vertebrobasilar arteries. Objectives: In the present study we tried to test the sensitivity of There is NO special preparation for a Transcranial Doppler (TCD) and/or Carotid Duplex study other than no facial makeup around the side of the face or temple area. You will not need to remove any clothing or do any other preparation.
