Background The aim of the study was to examine the impact of three‐dimensional power Doppler ultrasound (3D‐PDU) in fetal abnormalities involving the vascular system. Method Eighty seven selected pregnancies were included in the study. ATL HDI‐3000 and 5000 ultrasound equipment with integrated 3D‐Color Power Angio ® software were used. Data acquisition was done by the free‐hand‐technique and images were reconstructed online. Results Reconstruction was only possible in 56 out of the 87 (64%) considered pregnancies. These were abnormalities of placenta and umbilical vessels (n = 26), intra‐abdominal and intrathoracal anomalies (n = 12), renal malformations (n = 9), central nervous system (n = 4) as well as cardiac defects (n = 5). The main reasons for failure were fetal position and movements, overlapping with signals from neighboring vessels as well as the reduced attempts in 3D in an on‐line system. Details and figures of the potential field of interest in prenatal diagnosis are presented. Conclusions The study shows that 3D‐power Doppler can be applied in prenatal diagnosis. The method enables the visualization of main parts of the fetal vascular system under abnormal conditions with the exception of the fetal heart where a trigger system is still needed.
