For RVAWd, RVIDd, RVAWs, and RVIDs, see the LV measurement method.
X
MPA Diam, RPA Diam, and LPA Diam are measured under Aortic Valve Level in Parasternal
Short Axis View.
X
C Mode is mainly used for measuring reverse cardiac blood flow.
X
As PISA-Radius or PISA-Alias Vel. measurements require Velocity values, you have to select
color display for Velocity or Vel + Var in C Mode. For more information, see the ‘Color Doppler
Mode’ section in ‘Chapter 4. Diagnosis Mode’.
X
Tissue Doppler can be measured in TDI Mode.
