How to interpret umbilical artery doppler flow reports

Resistance Index(RI) =
Peak systolic velocity - End diastolic velocity
Peak systolic velocity
Pulsatility Index(PI)=
Peak systolic velocity - End diastolic velocity
Peak Mean velocity
Mean velocity is not available in Nagercoil scan report, so we can't find out the pulsatility index.
SD =
End diastolic velocity
Peak systolic velocity
