Overview. In 1982, Aaslid et al 1 authored a paper with the title “Noninvasive transcranial Doppler ultrasound recording of flow velocity in basal cerebral arteries,” describing the successful insonation and blood flow velocity (FV) measurement of the basal cerebral arteries with a range-gated Doppler transducer.

Transcranial Doppler ultrasound remains the only imaging modality that is capable of real-time measurements of blood flow velocity and microembolic signals in the cerebral circulation. We here assessed the repeatability and reproducibility of transcranial Doppler ultrasound in healthy volunteers and patients with symptomatic carotid artery stenosis.

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. Transcranial Doppler ultrasound allows measurements of blood flow velocity to be made from the basal intracerebral vessels. The major advantages of transcranial Doppler ultrasound are that it is non-invasive, relatively cheap, can be performed with portable machines, allows monitoring for prolonged periods, and has a high temporal resolution Transcranial​ ​Doppler ​ ​ (TCD)​, also known as transcranial colour-coded duplex sonography (TCCS) is a sonographic study of intracranial structures and blood vessels, used most commonly to identify the haemodynamic state present in the vertebrobasilar circulation and the circle of Willis. 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 of your brain.
