Key result
Transcranial Doppler is a noninvasive, inexpensive monitoring method that provides real-time physiological information about cerebral blood flow and vessels in stroke and cerebrovascular patients.
Why the study?
Transcranial Doppler relies heavily on examiner skill and experience and lacks standardized scanning protocols despite broadening clinical applications.
Transcranial Doppler is a valuable, noninvasive tool for assessing cerebrovascular hemodynamics, though its accuracy depends heavily on examiner skill.
TCD may aid bedside cerebrovascular monitoring where other imaging is limited; leaves open standardization of operator-dependent techniques.
Transcranial Doppler (TCD) was introduced in 1982 to assess intracranial arteries noninvasively, since when it has been widely used to assess and monitor cerebrovascular hemodynamics. The clinical applications of TCD are broadening to include other fields that require monitoring of the cerebral blood flow. TCD has fewer temporal and spatial restrictions than other methods, can be performed on less-compliant patients, and causes no harm to the body. However, its reliance on high levels of examiner skill and experience, as well as a lack of standardized scanning protocols are obstacles that still need to be overcome. In this report we review TCD examination techniques and interpret their findings for several conditions.

Do et al. (2019) conducted a review in Cerebrovascular hemodynamics. Transcranial Doppler (TCD) was evaluated. Transcranial Doppler is a noninvasive, inexpensive monitoring method that provides real-time physiological information about cerebral blood flow and vessels in stroke and cerebrovascular patients.
