ULTRASOUND MEASUREMENT OF THE FETAL HEAD TO ABDOMEN CIRCUMFERENCE RATIO IN THE ASSESSMENT OF GROWTH RETARDATION

Campbell, S., Thoms, Alison·1977·BJOG: An International Journal of Obstetrics & Gynaecology

Abstract

Summary: Fetal head and abdomen circumference measurements have been made using pulsed ultrasound techniques. The mean head to abdomen (H/A) circumference ratio with 95 per cent confidence limits was determined in 568 normal pregnancies from 17 to 41 weeks menstrual age. The mean ratio was 1·18 at 17 weeks, but decreased slowly until 29 weeks when the ratio was 1·11; thereafter there was a sharp fall in the mean ratio to 1·01 at 36 weeks and 0·96 at 40 weeks. The H/A circumference ratio was also determined in 31 small‐for‐dates fetuses within one week of delivery. In all cases the fetal weight as predicted from the fetal abdomen circumference measurement was below the 5th centile weight for gestation. The ratio was above the 95th centile limit in 22 (71 per cent) of these fetuses and evidence is presented to suggest that the H/A circumference ratio can be used to distinguish between symmetrical and asymmetrical growth retardation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
