Transcranial Doppler (TCD) is a non-invasive ultrasound technique, not utilizing ionizing radiation. This technique takes advantage of acoustic windows present in the skull to interrogate the intracranial vascular structures. Various vascular measurements can be determined, including cerebral blood ...Transcranial Doppler Ultrasound: Technique and …
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 …

- An extension of the non-imaging, continuous wave Dopplerassessment popular among neurointensivists, the imaging of cerebral structures with grey-scale and superimposed color flow and spectral Doppler analysis is now possible using the same windows, techniques, and diagnostic goals. Some may refer to the imaging modality to be discussed below as tra...
