WS08: Fetal brain WS08-01Three-dimensional-ultrasound of the embryonic/early fetal brain

Clinical application of three-dimensional ultrasound in fetal brain assessment.

AIM To clarify the usefulness of three-dimensional (3D) ultrasound in the assessment of the fetal head and brain, according to 3D ultrasound surface reconstruction, multiplanar image analysis, three-dimensional angiography, and volume calculation. METHODS We examined 326 normal fetuses between 10 and 40 weeks of gestation using 3D ultrasound (Voluson, 530D, Medison, Seoul, Korea), mainly with...

Examination of the fetal brain by transabdominal three-dimensional ultrasound: potential for routine neurosonographic studies.

OBJECTIVE To evaluate the role of transabdominal three-dimensional (3D) ultrasound in the assessment of the fetal brain and its potential for routine neurosonographic studies. METHODS We studied prospectively 202 consecutive fetuses between 16 and 24 weeks' gestation. A 3D ultrasound volume of the fetal head was acquired transabdominally. The entire brain anatomy was later analyzed using the ...

The impact of COVID-19 during pregnancy on fetal brain development

The development of the brain as the most complex structure of the human body is a long process that begins in the third week of pregnancy and continues until adulthood and even until the end of life (1). Human brain myelination begins one to two months before birth in the visual system and eventually lasts until the age of two in other sensory systems and then the motor systems (4). Processes a...

Quantitative analysis of normal fetal brain volume and flow by three-dimensional power Doppler ultrasound.

BACKGROUND Assessment of the fetal brain volume and blood flow is important in the evaluation of fetal growth. We used three-dimensional (3D) ultrasound and power Doppler to assess the fetal brain volume and the blood flow index during normal gestation. The relationships of these parameters were further analyzed. METHODS We assessed the total volume and the blood flow index of the fetal brain...
