TCD-Profiling Using AVERAGE. A New Technique to Evaluate Transcranial Doppler Ultrasound Flow Spectra of Subjects with Cerebral Small Vessel Disease.

Background: There is an unmet need for screening methods to detect and quantify cerebral small vessel disease (SVD). Transcranial Doppler ultrasound (TCD) flow spectra of the larger intracranial arteries probably contain relevant information about the microcirculation. However, it has not yet been possible to exploit this information as a valuable biomarker.
