Summary Fetal biparietal diameter, transverse thoracic diameter, abdominal circumference and area were measured by ultrasound in 50 pregnant women at term not more than 48 hours before delivery. Multiple regressions correlating birth weight with all these parameters were obtained and estimated birth weight (calculated from the regressions) was compared with the actual birth weight. The error in prediction was under 200 g in 56 per cent, under 300 g in 66 per cent and under 400 g in 84 per cent of patients when all fetal measurements were used. It was under 200 g in 48 per cent, under 300 g in 66 per cent and under 400 g in 74 per cent when only the abdominal area was used; and it was under 200 g in 46 per cent, under 300 g in 56 per cent and under 400 g in 82 per cent when the abdominal circumference alone was used. Biparietal diameter and transverse thoracic diameter alone were not useful in predicting birth weight.
