WebColour Doppler shows the direction of the blood flow in red or blue (either towards or away from the transducer). Meanwhile, spectral Doppler not only shows the direction of blood flow, it also shows the phases (pulsatility) and acceleration of the blood flow. Any sudden changes in direction of blood flow produces audible sounds on the ultrasound machine. WebColor Doppler echocardiography visualizes AR, then spectral Doppler is used to further interrogate the regurgitant jet. When using Doppler, beware of mistaking the normal LV inflow signal for a jet of AR because both these jets occur in diastole; AR jets tend to have a higher velocity and show more turbulence than the LV inflow signal.
