Sonographer Pal on Instagram: "LINK IN BIO! Aliasing (Color + PW Doppler): the “wrap-around” that can make flow look reversed (From our SonographerPal.com SPI Doppler Ultrasound Study Guide — shown here with both Color and Pulse Wave examples.) If you’ve ever seen a mosaic / color wrap on Color Doppler and a PW waveform that looks like it jumps to the other side of the baseline… that’s aliasing. What’s happening (SPI key concept): Aliasing occurs in pulsed Doppler when the Doppler shift exceeds
