Pulsed Wave Doppler
Advantage: Range Specificity
Disadvangtage: Aliasing
Continuous Wave Doppler
Advantage: Sample high velocities, no aliasing
Disadvantage: Range ambiguity
Color Doppler
Advantage: Determine direction of blood flow
Disadvantage: Aliasing
Power Doppler
Advantage: Sensitive to low velocitites
Disadvantage: Does not determine direction of blood flow
