• one cannot measure both speed and location at the same time
• pulse wave doppler measures speed at certain location but is limited by the Nyquist limit
• aliasing occurs when velocity exceeds Nyquist limit on pulse wave doppler
• continuous wave doppler measures peak velocity. Use continuous wave to measure high velocity flows¹
