In this fetus (see ultrasound images above), the size of the fetal head is normal , as are the lateral ventricles. However, the anteroposterior width of the cisterna magna is greater than 10 mm ( here it measures 12 mm) in the axial plane. In addition, the fetal cerebellum and the ...
Ultrasound images Faster R-CNNAnatomical structure detectionClinically, the transthalamic plane of the fetal head is manually examined by sonographers to identify whether it is a standard plane. This examination routine is subjective, time-consuming and requires comprehensive understanding of fetal anatomy...
These ultrasound images show a normal early fetus of 9 weeks gestational age (1st trimester) and are taken via the transabdominal route. Among the structures seen are the fetus with the bulkier head (cephalic part) and the fetal heart on Color Doppler and Power Doppler imaging. Spectral Doppler...
Early in the use of fetal ultrasound, clinicians could only detect the baby's head, Nicolson said. "But gradually, with developing expertise, they could discern fine structures in the fetus," he said. Is it safe? One of the main advantages of ultrasound is that it's noninvasive. The pro...
Automatic evaluation of fetal head biometry from ultrasound images using machine learning Ultrasound-based fetal biometric measurements, such as head circumference (HC) and biparietal diameter (BPD), are commonly used to evaluate the gestational...

Accurate estimation of gestational age is an essential component of good obstetric care and informs clinical decision-making throughout pregnancy. As the date of the last menstrual period is often unknown or uncertain, ultrasound measurement of fetal siz
Congenital heart disease (CHD) is one of the most common birth defects in the world. It is the leading cause of infant mortality, necessitating an early diagnosis for timely intervention. Prenatal screening using ultrasound is the primary method for CHD
Segmentation of a fetal head from three-dimensional (3-D) ultrasound images is a critical step in the quantitative measurement of fetal craniofacial structure. However, two main issues complicate segmentation, including fuzzy boundaries and large variations in pose and shape among different ultrasound ...
At least two cine clips were acquired through the head in an axial and coronal orientation, and through the chest and abdomen in an axial orientation. Doppler ultrasound of the middle cerebral artery was performed to evaluate the flow through the brain. Amniotic fluid index was calculated by ...
