Choice of standards for sonographic fetal abdominal circumference percentile

American Journal of Obstetrics & Gynecology MFM, 2022
The diagnosis of abnormal fetal abdominal circumference is based on values >90th or 1 eligible examination during the study period, a single examination was chosen at random for inclusion. Five norms of abdominal circumference were studied: the Hadlock formula, the World Health Organization Fetal Growth Curves, the International Fetal and Newborn ...

Percentile ranks of sonar fetal abdominal circumference measurements

American Journal of Obstetrics and Gynecology, 1980
We present the percentile ranks of sonar fetal abdominal circumference (AC) measurements from 18 to 41 weeks' gestation. The ACs are derived from both longitudinal and cross-sectional ultrasonic studies of 200 low-risk pregnant women. The reproducibility of sonar AC falls within 2% of the mean value; this variation permits antenatal distinction of the ...

Fetal head and abdominal circumferences: Ellipse calculations versus planimetry

Journal of Clinical Ultrasound, 1987
AbstractOne hundred twenty‐two images of fetal heads and abdomens were obtained by ultrasound. The head and abdominal circumferences and their ratios were determined by planimetry and by the ellipse method utilizing four different equations. The accuracy of these equations was assessed by regressing the circumferences and ratios obtained by the ...

Fetal abdominal circumference as a predictor of menstrual age

American Journal of Roentgenology, 1982
The relation between fetal abdominal circumference and menstrual cycle age was determined by cross-sectional analysis of 400 fetuses (15-41 weeks) examined with a linear-array real-time ultrasound scanner using specifically defined methodology. Mathematical modeling of the data demonstrated that the liner quadratic function was an optimal model (r2 ...

Characteristics and Outcome and the Omphalocele Circumference/Abdominal Circumference Ratio in Prenatally Diagnosed Fetal Omphalocele

Fetal Diagnosis and Therapy, 2011
<i>Objective:</i> To evaluate the outcome of fetuses with prenatally diagnosed omphalocele and to investigate the predictive value of the omphalocele circumference/abdominal circumference (OC/AC) ratio – a measure for the relative size of the omphalocele.

Optimal waist circumference cutoffs for abdominal obesity in Chinese

Atherosclerosis, 2008
To determine the appropriate cutoffs for visceral fat area (VFA) measured by magnetic resonance imaging linking to risk of the metabolic syndrome (MetS) and the corresponding waist circumference in Chinese.Totally 1,140 individuals (men 525, women 615) aged from 35 to 75 years were included.

Comparison of Different Sonographic Methods to Determine Fetal Abdominal Circumference

Fetal Diagnosis and Therapy, 2010
<i>Purpose:</i> In modern obstetric management, accurate estimation of fetal weight is an important prognostic parameter of neonatal morbidity and mortality, and a valuable tool for determining further treatment. Fetal abdominal measurements, mostly abdominal circumference (AC), are not only included in the majority of commonly used weight ...

Detecting fetal macrosomia with abdominal circumference alone.

The Journal of reproductive medicine, 2003
To determine if abdominal circumference (AC) can identify macrosomia (> or = 4,000 g) at or beyond 37 weeks.Prospectively, parturients at term admitted for delivery underwent sonographic mensuration of AC. A receiver-operating characteristic (ROC) curve was constructed to determine if AC can differentiate between normal (birth weight < 3,999 g) and ...
