Figure 3

Representation of the peak systolic, end diastolic and mean CBFVs. Envelope of two waves of CBFV derived by a TCD scan of the left MCA of a healthy subject. The figure reports the indications of the peak systolic velocity value (PV), of the end diastolic value (EDV), and of the mean velocity value (MV) that are used for the calculation of BHI V and of the pulsatility index.
