Ductus venosus waveform analysis has become increasingly affected by technical errors; however, these errors could be avoided if more attention was paid during sampling and analysis. The most common misevaluations include incorrect tracing, under‐ or overestimation of the peak systolic velocity, overestimation of the end‐diastolic velocity, and, as a consequence, incorrect calculation of the pulsatility index facilitated either by human or software error. This article proposes practical suggestions to avoid technical errors in ductus venosus waveform analysis. © 2008 Wiley Periodicals, Inc. J Clin Ultrasound, 2008
