Plus, the fundal height was almost 1cmshort of what it should be. Objective: The fetal abdominal circumference is the most sensitive ultrasound biometric measurement for predicting intrauterine growth restriction, which is associated with an increased risk of intrapartum fetal distress. Dolicocephaly is defined when the AP diameter is longer than the transverse diameter and the CI is <70% (> 2 SD). Used between 15-42 weeks. So the head measurements show my boy was now 33 weeks, so roughly 2 weeks ahead, where the abdominal measures at end of 29wk/beginning of 30 week, so a week and half behind.

The CI is an index or ratio which is used to evaluate the shape of the head. Incorrect imaging of AC. I mean, if a sono technician saw the brain anatomy being abnormal, he/she has to list it out, right? Biparietal diameter/femur length ratio, cephalic index, and femur length measurements: not reliable screening techniques for Down syndrome. In addition, head circumference tended to be 2.3 cm (95% CI: 20.0, 4.6 cm) larger when mothers consumed .3 glasses/d. At my practice the overall fetal weight would have to be less than the 10th percentile to be considered IUGR. 2011;284(4):827836.

Should I call again to ask for additional evaluation? The measurements that are used in equations to estimate weight usually include biparietal (head) diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur (thigh bone) length (FL). It is calculated by measuring the maximum width (BPD) of the cranium divided by its maximum length (occipital frontal diameter, OFD). in detecting the macrosomic fetus. Baby's growth was all within the normal parameters, but its abdominal circumference was on the higher side of normal, where as its head and femur sizes both showed as either in the middle or just . and transmitted securely. -, Boulet S L, Alexander G R, Salihu H M, Pass M. Macrosomic births in the united states: determinants, outcomes, and proposed grades of risk. The specialist uses the combination of the measurements mentioned above in a formula to calculate the fetus's weight and . 1.
