Biparietal diameter and femur length discrepancies: are maternal characteristics important?

Fetal biparietal diameter, head circumference, abdominal circumference and femur length. A comparison by race and sex.

Biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) were compared by race and sex in 5,405 ultrasound examinations done on 2,831 women. Black fetuses had significantly longer FL than white fetuses; male fetuses had larger BPD, HC and AC than females. The differences in BPD, HC and AC correlated with the different birth weights observed between ...

Ultrasound assessment of fetal biparietal diameter and femur length during normal pregnancy in Iranian women.

OBJECTIVES To determine the pattern of intrauterine growth and predicted biparietal diameter (BPD) and femur length (FL) at point in gestation of Iranian fetuses. METHODS In an extensive and long-standing prospective study in Tehran, Iran 15693 BPD and 15594 FL measurements were obtained from the fetuses of 1324 normal pregnant women. Weekly mean values and the standard deviations (S.D. ) wer...

Automatic Detection and Measurement of Fetal Biparietal Diameter and Femur Length—Feasibility on a Portable Ultrasound Device

An automatic method able to recognize a presented section through the biparietal plane of the fetal head and a section through the fetal femur in ultrasound images is developed. Once the correct anatomical section for measurement is identified by the machine, the placement of the measurement calipers is automatically determined by fitting an active contour model to the structure of interest. Th...

Use of fetal biometry in the assessment of gestational age in South East Nigeria: Femur length and biparietal diameter.

BACKGROUND Fetal growth is influenced by many factors such as race, socioeconomic status, genetics, geographical location, maternal diseases, and number of babies. Consequent upon these, fetal growth charts may vary from one location to another even within the same geographical entity. OBJECTIVE This study was designed to establish the fetal growth chart in antenatal women who had ultrasound ...
