Three-dimensional qualitative sonographic evaluation of fetal soft tissue.

I-60: Sonographic Evaluation of the Fetal SkeletalAnomalies

Two- and three-dimensional ultrasound for assessing potential airway obstruction in congenital epulis.

Epulis, or congenital granular cell tumor, is a rare benign tumor of the soft tissue in the oral cavity. Antenatal diagnosis has been reported rarely in the literature and incomplete evaluation is not uncommon1–3. Recently, a report on three clinical cases suggested that an ex-utero intrapartum treatment (EXIT) procedure may be useful when congenital epulis is diagnosed antenatally4. This proce...

Real-time three dimensional sonographic features of an early third trimester fetus with achondrogenesis.

Generalized shortening of fetal long bones detected from prenatal sonographic examination usually raise a tentative diagnosis of skeletal dysplasia. Information obtained from grey-scale scan is frequently not sufficient to provide a definite diagnosis, and the images are not readily comprehensible for the parents-to-be. Lately, three-dimensional sonography has become increasing available in obs...

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...

Prenatal diagnosis of herniated Dandy-Walker cysts.

OBJECTIVE The purpose of this series is to describe the prenatal diagnosis and pregnancy outcome of fetuses affected with Dandy-Walker malformation in which a posterior cyst herniated through a bony defect of the occipital skull, foramen magnum, or both. METHODS Two- and 3-dimensional sonography were used to examine 2 fetuses with poorly delineated cerebellar structures and a large posterior ...
