WHO multicentre study for the development of growth standards from fetal life to childhood: the fetal component.

Background: In 2006 WHO presented the infant and child growth charts suggested for universal application. However, major determinants for perinatal outcomes and postnatal growth are laid down during antenatal development. Accordingly, monitoring fetal growth in utero by ultrasonography is important both for clinical and scientific reasons.

Cervical sonography in women with symptoms of preterm labor.

In the last few years, ultrasound of the cervix during pregnancy has been the focus of much research. Significant advances have been made in its technique and in understanding the proper role of this procedure in several clinical settings. This article reviews the evidence for the clinical role of transvaginal cervical assessment in women with symptoms of preterm labor.

Reproducibility of fetal lung volume measurements with 3-dimensional ultrasonography.

Objective: To build a nomogram of normal fetal lung volumes and to assess the reproducibility of measurements using 3-dimensional ultrasonography.

Methods: Inclusion criteria were healthy women, singleton normal pregnancies, reliable dating, and 20 to 30 weeks' gestation. Exclusion criteria were discordance between clinical and ultrasonographic dating, patients lost to follow-up, and birth weight disorders.

Three-dimensional ultrasonography in gynecology: technical aspects and clinical applications.

Objective: The aim of this work was to review the technical aspects and clinical applications of three-dimensional ultrasonography in gynecologic imaging.

Methods: With the use of a computerized database (MEDLINE), articles on three-dimensional ultrasonography were reviewed. Other pertinent references were obtained from the references cited in these articles.
