Caution advised with Doppler PSV due to high variability; leaves open needs for standardization and training thresholds.
Does operator experience affect the reproducibility of Doppler ultrasound measurements?
Doppler ultrasound measurements exhibit poor reproducibility and significant interobserver variation, questioning the reliability of the method despite improvements with operator experience.
