Journal ArticleDOI
Accurate prediction of fetal hemoglobin by Doppler ultrasonography
TL;DR: Doppler measurement of the MCA‐PSV appears to be a valuable tool for estimating hemoglobin concentration in fetuses at risk for anemia, and the correlation between hemoglobin and MCA-PSV becomes more accurate as the severity of anemia increases.
