Ultrasound study of fetal stomach is multidirectionally rewarding . It can be used to detect congenital aberrations and to estimate gestational age in comparison with biparietal diamater (BPD). This study was performed in 60 pregnant women in 14-40 weeks of gestation. Maximum width and lengths of fetal stomach were measured and compared with BPD in order to determine gestational age . In 4 fetus, stomach was not visualized, This was caused by oligohydramnios in 2 and congenital neural tube defect in 1 case. Nonvisualization of fetal stomach after 14-20 weeks of gestation could be interpreted as indirect evidence of congenital abnormalities. In this study it was also noted that the measurements upleveled at 25th week of gestation resulting in the affecting parameters to intensify beyond this time. Ultrasound study was done only once without chronological repetition .
