Which of the following is NOT a correct method for handling pulsed wave Doppler aliasing?

Using a higher frequency probe is not a correct method for handling pulsed wave Doppler aliasing. Doppler aliasing occurs when the Doppler frequency shift exceeds half the pulse repetition frequency, leading to inaccuracies in velocity measurement. Increasing the frequency of the transducer does not solve the issue of aliasing; in fact, it can heighten the potential for aliasing because higher frequencies can lead to greater Doppler shifts, particularly in fast-moving structures.

Alternatively, shifting the baseline can effectively help in visualizing the waveform better in the presence of aliasing. This method adjusts the displayed baseline to accommodate higher velocities. Using continuous wave Doppler is another solution, as it allows for the measurement of higher velocities without the limitations imposed by the pulse repetition frequency. Finally, decreasing the sample volume can also reduce aliasing by allowing the detection of signals from a smaller area, thus potentially avoiding excessively high velocity readings that lead to aliasing.
