Growth of the fetal biparietal diameter in different types of pregnancies.

Radiology, 1980
A total of 24,560 fetal biparietal measurements were made using the B-scan technique. The increase in biparietal diameter was compared in normal pregnancies, in those complicated by diabetes or toxemia, and in fetuses thought to be small for dates. Only the last of these groups demonstrated a statistically significant difference.

Growth of the biparietal diameter of the fetal head in diabetic pregnancy

American Journal of Obstetrics and Gynecology, 1973
Abstract The biparietal diameter of the fetal head was measured by means of ultrasound in pregnancies complicated by diabetes mellitus. There were no differences in biparietal diameter between the fetuses of diabetic mothers and normal fetuses from the thirtieth through the thirty-seventh weeks. After this time, the measurements in diabetic pregnancy

GROWTH OF THE FETAL BIPARIETAL DIAMETER DURING NORMAL PREGNANCY

BJOG: An International Journal of Obstetrics & Gynaecology, 1971
SummaryThe fetal biparietal diameter was measured by ultrasound during normal pregnancy. The range of biparietal diameter values for each week of pregnancy from 13 weeks until term (1029 measurements) was determined and longitudinal data (646 measurements) were used to illustrate the variation in growth rate according to fetal maturity, head size and ...

A coded cephalometer for interactive multiple measurements of biparietal diameter

Ultrasound in Medicine & Biology, 1980
Abstract A coded cephalometer is described which allows multiple interactive independent measurements of the fetal biparietal diameter at one examination and comparative multiple measurement trials on the same patient using different equipments. The principles of the system are described, and in particular the methods of coding the displayed values ...

Reproducibility of Biparietal Diameter Measurements Obtained with a Real-Time Scanner

Obstetrical & Gynecological Survey, 1980
SummaryIn 80 patients, multiple measurements of the fetal biparietal diameter were made during one examination using a real‐time scanner equipped with a coded cephalometer. From the sets of data, the means and standard deviations for the group of 80 patients were calculated.

OCCIPITOFRONTAL‐BIPARIETAL DIAMETER RATIO

Medical Journal of Australia, 1979
The cephalic index of the fetal head was determined by the ultrasonic measurement of the occipitofrontal-biparietal diameter (OF-BPD) ratio in a pilot study of 53 patients at risk of Down's syndrome. The mean value of the OF-BPD ratio was 1.24, and a linear correlation between the occipitofrontal diameter (OFD) and the biparietal diameter (BPD) was ...

A COMPOSITE CURVE OF ULTRASONIC BIPARIETAL DIAMETERS FOR ESTIMATING GESTATIONAL AGE

Obstetrical & Gynecological Survey, 1977
A composite curve of biparietal diameters at various gestational ages was constructed from previous reports from five large centers. Estimates of the mean gestational age using the composite curve compared favorably with other reporting institutions. This suggests that the newly established echography department may employ the composite curve of mean ...

Ethnic Considerations in Ultrasonic Scanning of Fetal Biparietal Diameters

Australian and New Zealand Journal of Obstetrics and Gynaecology, 1981
Summary: Biparietal diameters (BPD) were determined by ultrasonography on 86 Caucasians and 107 Polynesians at different gestations. Analysis of variance showed a highly significant (p<0.01) difference between groups. At any gestational age, Polynesian fetuses had BPDs 1.89 mm greater than Caucasian fetuses and this fact must be taken into ...

Biparietal diameter in the Australian aboriginal fetus.

British journal of obstetrics and gynaecology, 1986
Fetal biparietal diameters (BPD) were measured by real time scanning on 657 occasions in 206 Aboriginal women attending for antenatal care in Arnhemland in the Northern Territory of Australia. Gestational age was estimated at birth for 202 of their infants and correlated with BPD measurements. Birthweights and BPD are compared with those for Aboriginal
