OP21.10: Three-dimensional sonographic fetal spleen volume measurement

Three-dimensional sonographic measurement of normal fetal brain volume during the second half of pregnancy.

OBJECTIVES This study was undertaken to develop a three-dimensional (3D) ultrasound method of measuring fetal brain volume. STUDY DESIGN Serial 3D sonographic measurements of fetal brain volume were made in 68 normal singleton pregnancies at 18 to 34 weeks of gestation. A comparison was made with fetal brain volume estimates from two-dimensional (2D) sonographic measurement of head circumfere...

Three-dimensional qualitative sonographic evaluation of fetal soft tissue.

Even though fetal growth restriction and macrosomia remain as major problems currently facing obstetricians, there is still no modality for the assessment of fetal soft tissue deposition and muscle mass in utero. A total of 52 fetuses from 29 to 41 weeks gestation were studied within 1 week before delivery using a transabdominal three-dimensional (3D) transducer (3.5 MHz). Their birth weights v...

Sonographic measurement of gallbladder volume.

Sonographic images of the gallbladder enable satisfactory approximation of gallbladder volume using the sum-of-cylinders method. The sum-of-cylinder measurements, however, are moderately cumbersome and time consuming to perform. In this investigation, in vitro and in vivo testing was done to determine that a simple ellipsoid method applied to sonographic gallbladder images yields reasonable vol...

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

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...
