OBJECTIVE The purpose of this study was to compare the diagnostic performance of ultrasonographic and digital examination of the cervix in the prediction of preterm delivery in patients presenting with preterm labor and intact membranes. STUDY DESIGN Endovaginal ultrasonography was performed in 59 patients admitted with preterm labor (20 to 35 weeks) and(More)
OBJECTIVE The aim of this study was to determine the value in the prediction of spontaneous preterm delivery of ultrasonographically measured cervical length measured between 14 and 24 weeks' gestation. STUDY DESIGN A retrospective cohort study examined cervical length by means of a two-stage procedure, transabdominal ultrasonography followed by(More)
OBJECTIVE The aims of this study were to determine if there is a relationship between middle cerebral artery (MCA) peak systolic velocity (PSV) and perinatal mortality in preterm intrauterine growth-restricted (IUGR) fetuses, to compare the performance of MCA pulsatility index (PI), MCA-PSV and umbilical artery (UA) absent/reversed end-diastolic velocity(More)
OBJECTIVE This study was undertaken to describe a new technique for the examination of the fetal heart using four-dimensional ultrasonography with spatiotemporal image correlation (STIC). STUDY DESIGN Volume data sets of the fetal heart were acquired with a new cardiac gating technique (STIC), which uses automated transverse and longitudinal sweeps of the(More)
OBJECTIVES This study was designed to compare a conventional multiplanar technique for three-dimensional (3D) ultrasound measurement of fetal lung volume with a rotational method using VOCAL trade mark (Virtual Organ Computer-aided AnaLysis). METHODS Thirty-two fetuses with a variety of conditions at risk for pulmonary hypoplasia were studied. 3D volume(More)
OBJECTIVE First-trimester fetuses with simple nuchal hygromas represent a population that is different from midgestation nuchal cystic hygroma in terms of karyotype abnormalities and long-term prognosis. STUDY DESIGN Sixty-eight consecutive fetuses diagnosed with simple nuchal hygromas between 10 and 14 weeks' gestation were evaluated ultrasonographically(More)
This study was undertaken to determine the incidence of prenatally, sonographically diagnosed clubfoot; the incidence of associated anomalies; and the correlation with postnatal findings. Cases of prenatally diagnosed clubfeet were abstracted from a prospectively entered ultrasound database. Scans were reviewed for the presence of associated anomalies.(More)
OBJECTIVE Our purpose was to determine whether cerclage placement in women with a short cervix on transvaginal ultrasonography reduces the rate of preterm delivery. STUDY DESIGN A retrospective cohort study identified patients with an ultrasonographic short cervix (cervical length < or =15 mm) between 14 and 24 weeks' gestation. Cerclage placement was(More)
The prenatal or postnatal factors that predict complex gastroschisis in patients (atresia, volvulus, necrotic bowel and bowel perforation) remain controversial. We evaluated the prognostic value of prenatal ultrasonographic parameters and early postnatal factors in predicting clinical outcomes. We analyzed maternal and neonatal records of 46 gastroschisis(More)
OBJECTIVES Two-dimensional (2D) matrix array is a new technology for the performance of 3-dimensional and 4-dimensional (4D) ultrasonography. In this study, we report the use of a 2D matrix array transducer for examination of fetal structures including the fetal heart. METHODS Thirty-four fetuses without abnormalities and 19 fetuses with congenital(More)
