In an earlier study we presented a method of determining fetal weight from ultrasound
measurements of abdominal circumference (AC) and biparietal diameter (BPD). From an
equation with these two measurements as independent variables we generated tables
of estimated fetal weights (E1). Although these tables have been very useful, we had
the impression we were underestimating fetal weight. Therefore, we reconsidered an
earlier unpublished table generated from a different equation (E2). While most estimates
from E1 and E2 were likely to be within 10% of actual weight, there was significant
underestimation with E1. E2 provides a better balance between the distribution of
overestimations and underestimations.
