Head Circumference of the fetus: table

Content: The research is conducted by specialist from several perspectives to obtain the most accurate result. In addition to the diagnosis of head circumference the doctor diagnoses geometricheskih such factors as the biparietal (BDP) and sagittal size, bone length of femur, abdominal circumference, frontal-occipital (LZR) size and others. A table of rules, applied to diagnostics, a technician can determine the development of the fetus and of potential bias. If the doctor detects a significant deviation from the norm, the woman offer to do an abortion. The Formula for the calculation
Head Circumference of the fetus by weeks is determined according to the same principle as the biparietal size: measured by this method as computed planimetry, or by formula. Pre-determined and LZR biparietal head size. The formula is as follows: OG = 1/2 * (LZR + BDP) * 3,1416. This indicator is rarely used to calculate fetus weight and does not depend on the shape of his head.
