Echo Modalities and their Main Uses
Echocardiography provides both anatomical and haemodynamic information:
- Heart chamber size
- Chamber function (systolic and diastolic)
- Valve motion and function
- Cardiac masses (intra and extra) and fluid collection
- Direction of blood flow and haemodynamic information by Doppler
echo.
Echocardiography includes both imaging (2-D and M-mode) and Doppler
modalities (continuous wave, pulsed wave and colour flow mapping).
