[Estimation of fetal weight by ultrasound (author's transl)].

[Article in German]


In attempt to estimate birth weight in utero several dimensions of fetal head and trunk cross-sections, obtained by ultrasonic A- and B-scan techniques (Kretz-Technik), were related to postnatal weights in 108 normal and abnormal pregnancies. Abdominal parameters showed better correlation with weights than did head parameters. Evaluations derived from mean diameter, circumference or area yielded more accurate estimations than those derived from single diameter. In addition, the combination of both head and abdomen measurements increased accuracy. The best results were obtained by planimetric determination of head and trunk cross-sectional areas. Using this method the standard error of estimates was 233 gm. as compared with 423 gm. employing biparietal diameter alone.
