PURPOSE to evaluate the embryo's volume (EV) between the seventh and the tenth gestational week, through tridimensional ultrasonography. METHODS a transversal study with 63 normal pregnant women between the seventh and the tenth gestational week. The ultrasonographical exams have been performed with a volumetric abdominal transducer.

AIM Assess vascular indices of 7-10 week embryos using three-dimensional power Doppler (3DPD) and correlate them with the crown-rump length (CRL). METHODS This cross-sectional study included 65 healthy pregnancies between 7 and 10 weeks. The three-dimensional volume of the embryo was obtained using an endocavitary volumetric transducer and the VOCAL(More)
OBJECTIVE To compare different three-dimensional (3D) methods in the assessment of gestational sac volume (GSV). DESIGN Cross-sectional study involving 74 normal pregnancies between 7 and 11 weeks. SETTING Department of Obstetrics, São Paulo Federal University (UNIFESP). METHODS GSV was measured through 3D ultrasound using the planimetric, virtual(More)
OBJECTIVE: To evaluate the interobserver reproducibility of vascular indices obtained with three-dimensional power Doppler (3D power Doppler) ultrasonography at the first trimester of gestation. MATERIALS AND METHODS: The present reproducibility study involved 32 healthy pregnant women with 7 to 10 weeks and 6 days of gestation. The VOCAL (Virtual Organ(More)
We sought to establish normative data for three-dimensional ultrasound (3DUS) first-trimester embryonic volume using the extended imaging virtual organ computer-aided analysis (XI VOCAL) technique. This cross-sectional study involved 64 normal pregnancies at 7 to 10 + 6 weeks' gestation. Embryonic volume was obtained on 3DUS using the XI VOCAL technique(More)
