Prenatal aneuploidy screening changed significantly in 2012 when cell-free fetal deoxyribonucleic acid (DNA) was introduced as a noninvasive prenatal test. A noninvasive prenatal test detects cell free fragments of fetal DNA from the placenta circulating in maternal blood that coexist with cell-free DNA (cfDNA) of maternal origin. Using next-generation sequencing, the noninvasive prenatal test compares maternal and fetal cfDNA ratios for chromosomes of interest (i.e., 21, 18, 13, X, and Y) to assess chromosomal aneuploidy...

Abnormal fetal growth significantly increases neonatal mortality and the risk of stillbirth. This creates the need for accurately monitoring fetal growth in all pregnancies regardless of the risk status. Several methods used in clinical practice include abdominal palpation, symphysio-fundal height measurements, and obstetric ultrasound. Of these, obstetric ultrasound remains the most reliable and objective way to monitor fetal growth. However, in most low-resource areas, access to obstetric ultrasound remains poor and this leaves the two as the only options available...

Thanatophoric dysplasia (TD) and achondroplasia (ACH) are allelic disorders caused by a constitutively active mutation in the FGFR3 gene. Because TD is a lethal disorder and ACH is non-lethal, they need to be distinguished after ultrasound identification of fetal growth retardation with short limbs. Accordingly, we have developed a noninvasive prenatal test using cell-free fetal DNA in the maternal circulation to distinguish TD and ACH. A multiplex PCR system encompassing five mutation hotspots in the FGFR3 gene allowed us to efficiently identify the responsible mutation in cell-free DNA in all examined pregnancies with a suspected TD or ACH fetus...

We present a general framework for automatic segmentation of fetal brain structures in ultrasound images inspired by recent advances in machine learning. The approach is based on a region descriptor that characterizes the shape and local intensity context of different neurological structures without explicit models. To validate our framework, we present experiments to segment two fetal brain structures of clinical importance that have quite different ultrasonic appearances-the corpus callosum (CC) and the choroid plexus (CP)...

BACKGROUND: Fetal occiput posterior position in labor is associated with more painful and prolonged labor, and an increase in both maternal and fetal morbidity. The aim of this study is to assess whether the modified Sims position on the side of the fetal spine increases the rotation to occiput anterior position in women with epidural analgesia and a fetus in persistent occiput posterior (POP) position. METHODS: This is an open, randomized controlled, clinical trial...

BACKGROUND: Absence of the CSP on prenatal imaging is historically associated with additional anomalies, however recently cases of isolated, absent CSP have also been identified. This study seeks to assess the accuracy of prenatal imaging in evaluating isolated, absent CSP and to describe the spectrum of clinical outcomes. METHODS: This is a retrospective observational study of all prenatally diagnosed absent CSP cases between 2011 and 2016 at our institution. Cases with additional structural parenchymal abnormalities were excluded...

Background: Early prediction of adverse neonatal outcome would be possible by Doppler impedance indices of middle cerebral artery (MCA), umbilical artery (UmA), and descending aortal artery (AO) that result in decrease neonatal morbidity and mortality rate. The aim of the present study was a determination of optimal value for the ratio of MCA to descending aorta blood flow (MCA/AO) impedance indices and its comparison with the ratio of MCA to UmA (MCA/UmA) impedance indices and their relationship with neonatal outcome...

Congenital aneurysms and diverticula of the heart are rare anomalies and their prenatal diagnosis is challenging. Fetuses with suspected cardiac aneurysms on ultrasound (US) screening should undergo targeted fetal echocardiography, postnatal imaging, and follow-ups. Herein, we describe the second trimester US scan and postnatal cardiac magnetic resonance imaging (MRI) findings of a baby girl with concurrent septal and right ventricular cardiac aneurysms. Other cardiac and extra-cardiac structures were normal...

BACKGROUND: Fetal cardiovascular magnetic resonance (CMR) imaging may provide a valuable adjunct to fetal echocardiography in the evaluation of congenital cardiovascular pathologies. However, dynamic fetal CMR is difficult due to the lack of direct in-utero cardiac gating. The aim of this study was to investigate the effectiveness of a newly developed Doppler ultrasound (DUS) device in humans for fetal CMR gating. METHODS: Fifteen fetuses (gestational age 30-39 weeks) were examined using 1...

Background: Limited epidemiological studies have investigated the relationship between prenatal exposure to ambient particulate matter and risk of abnormal fetal growth, and have reached inconclusive results. No study has been conducted in areas with very high air pollution levels. We investigated the hypothesis that exposure to high levels of particulate matter with aerodynamic diameter no larger than 10 µm (PM10) during pregnancy increases the risk of abnormal fetal growth. Methods: A birth cohort study was performed in Lanzhou, China, 2010-12, including 8877 pregnant women with 18 583 ultrasound measurements of four fetal growth parameters during pregnancy, including biparietal diameter (BPD), femur length (FL), head circumference (HC) and abdominal circumference (AC)...
