Transcranial Doppler Examination Techniques

  • R. Aaslid


The first step in a transcranial Doppler examination is to localize a cranial “window” where the ultrasonic beam can penetrate without being excessively damped. It is necessary that the operator acquires the skill to optimize probe positioning and angle to achieve sufficient signal strength. The next step is that of identifying the signals from the different segments of the arterial network at the base of the skull. This identification is primarily based upon anatomical knowledge and sample volume position. The characteristics of Doppler signals from various segments and their response to compression maneuvers present further information for identification.
