Transcranial doppler ultrasound (TCD) is a non-invasive ultrasound method used to examine the blood circulation within the brain. Your doctor has recommended that you have this test to determine the amount of blood flow to certain areas o

What is Transcranial Doppler (TCD) ultrasound? A Doppler machine is similar to the ultrasound machines used during pregnancy. It detects the rate of blood flow in blood vessels. 'Transcranial' means it is used to look at the vesse

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.

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. During the test: Indications for the clinical use of transcranial Doppler (TCD) continue to expand while scanning protocols and quality of reporting vary between institutions.
