Laminar flow assessment. a) CD and PW showing a flow pattern with parabolic profile (arrows) and minor spectral broadening (*), respectively. b) VFI at the peak systole shows the maximum velocity vectors. Low-velocity vectors (*) of the previous diastole. Maximum velocity point (void arrow). Yellow line (arrowhead): the moment the VFI frame was acquired. CCA = Common carotid artery
