Quantitative assessment of gestational sac shape: the gestational sac shape score.
OBJECTIVE To develop a quantitative method for characterizing gestational sac shape. METHODS Twenty first-trimester gestational sacs in normal pregnancies were studied with three-dimensional (3D) ultrasonography. The 3D coordinates of surface-point sets were obtained for each sac using 30-, 15- and six-slice sampling. Cubic spline interpolation was used with the 15- and six-slice surface-poin...
متن کامل[Estimation of gestational age by ultrasonic measurements of the gestational sac].
One hundred and eighty gestational sac (GS) measurements by ultrasound echography were performed on 132 healthy pregnant women with an accurate gestational age of between five and twelve weeks. Their prenatal courses were uneventful and they delivered of babies appropriate for dates at term. The GS longest diameter in longitudinal section (LGS), the GS longest diameter making perpendicularity t...
متن کاملAutomatic Gestational Age Estimation Based on Crown Rump Length and Gestational Sac
The development of ultrasound technology allows us to see the structure and development of the fetus directly. Crown-Rump Length (CRL) and mean diameter of gestational sac (MSD) can be used to determine the age of the fetus. Both parameters are useful for measuring different aspects of the first trimester of pregnancy. This study proposes a method to obtain those parameter values automatically ...
متن کاملNormal ranges of embryonic length, embryonic heart rate, gestational sac diameter and yolk sac diameter at 6-10 weeks.
OBJECTIVES To construct normal ranges for embryonic crown-rump length (CRL), heart rate (HR), gestational sac diameter (GSD) and yolk sac diameter (YSD) at 6-10 weeks of gestation. METHODS We examined 4,698 singleton pregnancies with ultrasound measurements of CRL, HR, GSD and YSD at 6-10 weeks and CRL at 11-13 weeks resulting in the live birth after 36 weeks of phenotypically normal neonates...
متن کاملEffectiveness of early medical abortion using low-dose mifepristone and buccal misoprostol in women with no defined intrauterine gestational sac.
BACKGROUND The study was conducted to assess the effectiveness of early medical abortion (EMA) in women with early pregnancy and no defined intrauterine gestational sac (IUGS) on ultrasound. STUDY DESIGN Retrospective, multicenter, observational study of oral mifepristone 200 mg and buccal misoprostol 800 mcg administered 24-48 h later for EMA (gestations ≤ 63 days). Odds ratios (ORs) [95% co...
