Summary. The accuracy of ultrasonic measurements of intra-amniotic ume using a parallel planimetric area method was assessed in 18 women by comparison against different measures of the same ume space. In nine patients undergoing second-trimester termination of pregnancy amniotic fluid ume was measured using a dye dilution method and fetal ume was measured by either water displacement or calculated from fetal weight. The estimated intra-amniotic ume by this method was not significantly different from the ultrasonic measurement. In one patient who had a hysterotomy, fetal and amniotic fluid umes showed a difference of 1.01% between ultrasonically-measured and actual intra-amniotic ume. In eight patients studied in the third trimester the mean difference between ultrasonic and estimated intra-amniotic ume at delivery was 6.2%.
