Development of Gestational Age-Specific Nomograms for Fetal Splenic Artery Doppler Parameters Between 18 and 40 Weeks of Gestation
OBJECTIVE: To characterize the gestational age-related behavior of fetal splenic artery (SA) Doppler parameters and to establish appropriate reference models for the systolic/diastolic (S/D) ratio, pulsatility index (PI), peak systolic velocity (PSV), and time-averaged maximum velocity (TAMV) in normal singleton pregna...
