OC078: Three-dimensional ultrasound fetal volume measurement: a study comparing the multiplanar technique with the rotational (VOCAL) technique

Is portable three-dimensional ultrasound a valid technique for measurement of postpartum urinary bladder volume?

OBJECTIVE To determine the accuracy of bladder volume (BV) measurement and to identify factors that influenced the ultrasound bladder scanner (UBS) measurement of BV in postpartum women compared with transurethral catheterization. MATERIALS, METHODS AND RESULTS A total of 190 paired measurements were performed on 190 women aged between 16 and 47 years. Majority of the women (36.9%) were in th...

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...

Reference intervals of fetal cisterna magna volume by two-dimensional method using the multiplanar mode of three-dimensional ultrasonography*

OBJECTIVE To establish reference intervals for the fetal cisterna magna volume by means of two-dimensional (2D) method using the multiplanar mode of three-dimensional ultrasonography. MATERIALS AND METHODS Cross-sectional study with 224 healthy pregnant women between the 17th and 29th gestational weeks. The volume was automatically obtained by multiplying the three major axes in axial and sag...

Three-dimensional ultrasound STIC-HDlive rendering: new technique to assessing of fetal heart

Congenital heart diseases (CHD) are the most common fetal congenital malformations, corresponding to an incidence six higher than chromosome anomalies and four higher than neural tube defects [1]. The prevalence of CHD in newborns ranges from 0.6% to 5% [2]. It's too known that the prenatal diagnosis can modify the outcome of some types of CHD [3,4]. The two-dimensional echocardiography is the ...
