Three-dimensional ultrasound examination of the fetal hands: normal and abnormal

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 ...

Fetal Heart Assessment Using Three-dimensional Ultrasound

Cardiac anatomy is complex and often difficult to visualize or comprehend. 3D echocardiography is an area undergoing rapid development that represents a natural extension of conventional sonography methods which require integrating a series of 2D image slices to develop a 3D impression of underlying anatomy or pathology. This paper will review some of the basic concepts behind three-dimensional...

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...

Three-dimensional Ultrasound in the Assessment of Fetal Limb Volume*

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...
