Prediction of Gestational Age According to Fetal Femur Length
SUMMARY Determination of gestational age have several usages in obstetrics and gynecology. The relation between fetal femur length and gestational age has determined in this research using real time sonography. 1000 iranian pregnant women between 12-40 weeks of gestation with accuratic last menstrual period and with out the history of diabetes lllellitus, hypertension, renal disease and fetal ...
متن کاملCorrected formula for uncertainty in estimations of gestational age from fetal head circumference measurements.
Over recent years, numerous publications have proposed methods for estimating gestational age (GA) using fetal measurements, including biparietal diameter, head circumference (HC) and crown–rump length, among others. The paper by Altman and Chitty1 presented statistical modelling of data from 663 fetuses to produce charts and tables for pregnancy dating based upon such measures. The resulting o...
متن کاملPostnatal Prediction of Gestational Age Using Newborn Fetal Hemoglobin Levels
INTRODUCTION In many parts of the developing world procurement of antenatal gestational age estimates is not possible, challenging provision of appropriate perinatal care. This study aimed to develop a model for postnatal gestational age estimation utilizing measures of the newborn hemoglobin levels and other metabolic analyte data derived from newborn blood spot samples. METHODS We conducted...
متن کاملUltrasonographic fetal scapular length measurement for assessment of gestational age
one of the major goals of antenatal care is estimation of gestational age.the most widely used parameters for evaluation of fetal growth are biparietal diameter (BPD),femoral length (FL) and adbominal circumference (AC).to determine the value of prenatal ultrasonographic scapula measurements for fetal growth and gesattional age a prospective ultrasonographic cross-sectional study was conducted ...
متن کاملLearning-based prediction of gestational age from ultrasound images of the fetal brain
We propose an automated framework for predicting gestational age (GA) and neurodevelopmental maturation of a fetus based on 3D ultrasound (US) brain image appearance. Our method capitalizes on age-related sonographic image patterns in conjunction with clinical measurements to develop, for the first time, a predictive age model which improves on the GA-prediction potential of US images. The fram...
