Functional Imaging of Cerebral Blood Flow Using Transcranial Doppler Ultrasound

Abstract

Source: Hage, B. D. et. al., Functional Transcranial Doppler Ultrasound for Monitoring Cerebral Blood Flow. J. Vis. Exp. (2021)

This video demonstrates the use of Doppler ultrasound as a functional imaging tool to measure cerebral blood flow velocity, or CBFV in real time. It highlights how frequency shifts in the middle cerebral artery during tasks like breath-holding reveal changes in CBFV, offering insights into brain activity and vascular dynamics.

Protocol

All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board.
