Reliability of Fetal Middle Cerebral Artery Velocity Measurements

Abstract

The reliability of fetal MCA PSV measurements improved after a targeted training program.

Interobserver Variability of Sonography for Prediction of Placenta Accreta

“…Interobserver variability for other obstetric sonographic measurements (eg, amniotic fluid volume, fetal biometry, and measurements of the fetal circulation) has been shown to vary widely 37 – 41 . For example, measurements of fetal biometry tend to be very reliable, 39 , 40 whereas measurements of amniotic fluid volume 37 , 38 and the fetal circulation 37 , 41 are less reproducible. The use of sonography to predict the presence or absence of accreta is more complex.…”
