By using a 1–2-MHz pulsed Transcranial Doppler (TCD), it is possible to penetrate the skull bone at special sites (windows) and register the flow velocity (FV) in the insonated artery at well-defined depts. In this way, the FV can be registered in the central arteries as well as in some of the veins.

Der Einsatz der transkraniellen Dopplersonographie ist auch bei der niedrigen Sendefrequenz von 2 MHz und der hohen emittierten Ultraschallenergie von bis zu 35o mW nur an Stellen niedrigerer Knochendichte bzw. bei der Beschallung durch Weichteile moglich.

Abstract Introduction: The multicenter phase 3 randomized clinical trial TCD With Transfusions Changing to Hydroxyurea (TWiTCH, NCT01425307) investigated whether hydroxyurea could maintain TCD velocities and prevent stroke in children with sickle cell anemia and abnormal TCD velocities.
