Fetal lung volumetry by three-dimensional ultrasound

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...

Measurement of fetal nuchal translucency thickness by three-dimensional ultrasound.

OBJECTIVE To investigate the feasibility and repeatability of nuchal translucency thickness measurement using three-dimensional ultrasound. METHODS Forty consecutive women with uncomplicated singleton pregnancies attending for Down syndrome screening at 11-14 weeks' gestation were included in this prospective crossover trial. Nuchal translucency thickness was measured using both two-dimension...

Prenatal imaging of facial clefts by two-dimensional and three-dimensional ultrasound and fetal magnetic resonance

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...

An introduction to fetal neurosonography using three-dimensional ultrasound

Multiplanar mode: nomenclature The multiplanar mode is probably the most useful tool for assessment of the fetal central nervous system (CNS). With this mode of display, the plane parallel to the acquisition plane or “start” appears in the upper left corner of the screen and is identified with the letter A. The plane perpendicular to A, but parallel to the ultrasound beam, is identified with th...
