Assessment of modified myocardial performance index in foetuses with growth restriction.

Aim: To evaluate the modified myocardial performance index (Mod-MPI) in foetuses with growth restriction and compare this index with appropriate for gestational age foetuses.

Material And Methods: A prospective cross-sectional case-control study was conducted involving 76 singleton foetuses between 24 and 34 weeks of gestation divided into three groups (24 appropriate growth foetuses, 30 foetuses with estimated weight between the 3rd and 10th percentiles and 22 foetuses with estimated weight < 3rd percentile, according to the Hadlock table). The Mod-MPI was obtained in the plane of the four chamber view, and the spectral Doppler sample volume was placed in the lateral wall of the aorta, close to the mitral valve.

Assessment of Intracranial Structure Volumes in Fetuses With Growth Restriction by 3-Dimensional Sonography Using the Extended Imaging Virtual Organ Computer-Aided Analysis Method.

Objectives: To assess intracranial structure volumes by 3-dimensional (3D) sonography in fetuses with growth restriction.

Methods: We conducted a prospective cross-sectional case-control study involving 59 fetuses with growth restriction (38 fetuses with estimated weight <3rd percentile and 21 fetuses with estimated weight between 3rd and 10th percentiles, according to Hadlock et al [Radiology 1984; 150:535-540]) and 54 controls between 24 and 34 weeks' gestation. The following fetal intracranial structure volumes were assessed: cerebellum, brain, and frontal region.

Fetal thigh and upper-arm volumes by three-dimensional ultrasound to predict low postnatal body mass index.

Objective: To assess the usefulness of estimating fetal upper arm and thigh volumes as predictors of low postnatal body mass index (BMI) using three-dimensional ultrasonography (3DUS) with extended imaging virtual organ computer-aided analysis (XI VOCAL).

Methods: This prospective cross-sectional study analyzed 300 singleton pregnancies between 33 and 41 weeks of gestation. The Hadlock 4 formula was used to estimate fetal weight.

Fetal thigh volume by 3D sonography using XI VOCAL: reproducibility and reference range for Brazilian healthy fetuses between 20 and 40 weeks.

Objective: To provide reference values for fetal thigh volume using three-dimensional (3D) ultrasound and the eXtended Imaging Virtual Organ Computer-aided AnaLysis (XI VOCAL) method.

Methods: This is a cross-sectional study that enrolled 425 healthy pregnant women between the 20(th) and 40(th) weeks of gestation. The XI VOCAL was performed along the axial cross-section in ten sequential areas for the volumetric calculations, having the proximal and distal echogenic diaphysis as references.

Nomogram of fetal upper arm volume by three-dimensional ultrasound using extended imaging virtual organ computer-aided analysis (XI VOCAL).

Aim: To define the reference range of the fetal upper arm volume by three-dimensional (3D) ultrasound using the eXtended Imaging Virtual Organ Computer-aided AnaLysis (XI VOCAL) method.

Methods: This prospective, cross-sectional study enrolled 425 healthy pregnant women with 20-40 weeks of gestation. The XI VOCAL technique was used for the volumetric calculations, considering 10 sequential sectional plane areas, performed along the axial plan of the fetal upper arm.
