Donald and Brown were the first users of ultrasound for measuring the fetal biparietal
Fetal cerebellar diameter in normal gestation is also highly correlated with fetal growth indices, such as biparietal
diameter, head circumference and abdominal circumference5.
Para la toma del diametro biparietal
se uso un ecografo SonoAce Pico (Samsung Medison, Corea) con transductor microconvexo de 4-9 MHz.
The ultrasound machine formula for estimating fetal weight was that devised by Hadlock on the basis of biparietal
diameter (BPD), head circumference (HC), abdominal circumference (AC), and femoral length (FL).
Table 4 shows that the majority of respondents consumed about 50-70 g protein per day, and the foetal growth measurements, such as abdomen-circumference, femur length, biparietal
diameter, and head-circumference, on average, were higher in the same group compared to the first and the third group.
Kopta MM, May RR, Crane JP A comparison of the reliability of the estimated date of confinement predicted by crown-rump length and biparietal
Gestational age can be assessed by accurate measurements of biparietal
diameter, head circumference, femur length and abdominal circumference.
A los 15 dias se midio, en al menos 2 embriones de cada cuerno, la longitud total del feto (CRL), el diametro biparietal
(DBP) y longitud occipito-nasal (LON), el diametro toracico (DTC) y el grosor de la placenta.
En esa oportunidad, se diagnostico un TEC cerrado con fractura craneal biparietal
de tipo lineal y contusion hemorragia subyacente.
In the last week pf pregnancy or before delivery an obstetrician should confirm by ultrasound the numbers of fetus, fetal position, presentation, position of placenta, measurement of the biparietal
dimension and femoral length, fetal heart frequency and fetal movements and amount of amniotic fluid which is maximum at 20-30 weeks.
Facial abnormalities incude macrocephaly, broad facies, frontal and biparietal
bossing, mild mandibular prognathism, odontogenic keratocysts ofjaws, misshapen and/or carious teeth, cleft lip and palate, ectopic calcification of falx cerebri.
After 13 weeks of gestation, the foetal age may be estimated by the biparietal
diameter (the transverse diameter of the head), the head circumference and the length of the femur (the longest bone in the body).
