ABSTRACT: After analyzing similar data, the National Institutes of Health Consensus Task Force on Ultrasound in Pregnancy and the comparable British body reached opposite conclusions on the value of routine early pregnancy ultrasonography. Ultrasound appears useful in various clinical situations and as a screening technique in early pregnancy. Of five controlled trials of routine late-pregnancy ultrasound screening, four failed to show a benefit and a fifth may have shown decreased perinatal mortality. A study of late-pregnancy ultrasound screening where the product of fetal crown-rump length and trunk area was calculated was highly effective in predicting small-for-dates infants, although no outcome or management benefits were shown.
