2024年4月15日 · In this study, an automatic, objective and reliable determination of fetal sex was aimed at using deep transfer learning techniques on USG images. For the study, a dataset containing 4400 fetal USG images, of which sexes were labeled by a gynecologist expert in the field, was created.

2006年2月21日 · Ultrasound determination of fetal sex can benefit decision-making regarding invasive prenatal testing in pregnancies at risk of sex-linked genetic abnormalities. The aim of this study was to assess the accuracy of fetal sex determination by ultrasound at 12–14 weeks of gestation in a large cohort.

2023年5月22日 · Fetal ultrasonography is an essential element in the evaluation of anomalies and fetal well-being throughout pregnancy. The increasing incidence of morbid obesity, hypertension, and gestational diabetes within the reproductive age group places this high-risk population at increased adverse fetal events such as stillbirth and fetal anomalies.

2019年5月29日 · Determination of fetal sex is an integral part of routine second trimester ultrasound examination in pregnancy, and it is usually accomplished (Figure 1), despite the occasional challenge presented by unfavorable fetal presentation, position and …

2004年1月1日 · Ultrasonography (US) is performed during early pregnancy for dating, determination of the number of fetuses, assessment of early complications, and increasingly for evaluation of the fetus, including measurement of the thickness of the nuchal translucency (NT).

Key measurements can include the crown-rump length (CRL), biparietal diameter (BPD), femur length (FL), head circumference (HC), occipitofrontal diameter (OFD), abdominal circumference (AC), and humerus length (HL). Additionally, they can help calculate the estimated fetal weight (EFW). What Fetal Measurements can be Calculated During Pregnancy?
