Many regression equations are available using various combinations of parameters to estimate the gestational age. in mm Diastolic MV in mm IVC in mm In most cases, BPD [Biparietal diameter], HC [Head circumference], AC [Abdominal circumference] and FL [Femur length] are used. The measurements of fetal HC, AC and FL are plotted on the reference range with gestational age reported by: Snijders RJ, Nicolaides KH. Put the measurements in the Baby 2 see calculator and BPD came out as 22 weeks so a week ahead, the others days ahead so I'm not worried. The gestational age calculator allows you to use the gestational sac or crown-rump length for first-trimester measuring. In order to calculate fetal length, you will need only the FL measurement, which represents the length of the femur. In the second trimester this may be extrapolated to an estimate of gestational age and an estimated due date (EDD). The results should be used as examples of gestational age determination and fetal size and growth calculation and only for the gestational age ranges indicated in the respective publications.

BPD: biparietal diameter (the diameter between the 2 sides of the head … It is common to make at least 2 and often 4 or 5 measurements to estimate gestational age. The fetal biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL) and foot length were measured. - BabyCenter Canada from the work of Koenker [26,27]. Just look at the ultrasound report that you get from the doctor. HC - Head Circumference The accuracy of gestational age calculated from HC is sligtly better than that derived from BPD. To calculate the estimated fetal weight, four measurements (AC, BPD, HC, FL) are entered into a mathematic formula. The BPD, HC, AC, and FL measurements were obtained and the mean gestational ages of combinations of these parameters were averaged to obtain a mean gestational age. The weight of the fetus at any gestation can also be estimated with great accuracy using polynomial equations containing the BPD, FL, and AC. The most commonly used measurements for gestational age assignment are the biparietal diameter (BPD), occipitofrontal diameter (OFD), head circumference (HC), abdominal diameter (AD), abdominal circumference (AC), and femur length (FL). Results. The fetal FL/BPD, FL/AC and FL/foot ratios were calculated in both the study and the control groups. Since all of these measurements are strongly related to gestational age, it is not usually important how they are combined. How to use the BPD, HC, AC, FL calculator?
