OBJECTIVE: To describe the prenatal imaging features enabling diagnosis of developmental venous anomalies (DVA). METHODS: Four fetuses with unexplained persistent echogenic parenchymal brain lesions were studied. The evaluation included dedicated neurosonography, fetal MRI, serology for intrauterine infection, screening for coagulation abnormalities, and chromosomal microarray. Postnatal neurodevelopmental follow-up or autopsy results were assessed. RESULTS: DVA presented as very slowly growing echogenic brain lesions without cystic components, calcifications, or structural changes on otherwise normal neurosonographic scans performed at 2- to 3-week intervals...

The aim of this study was to characterize the clinically relevant genital tract disorders of dromedary camels. Reproductive tract examinations were performed via transrectal palpation, ultrasonography and vaginal exploration. The ultrasonic appearance of the reproductive pathology was described and compared with its morphology at laparotomy, after surgical removal, during postmortem examination or upon slaughter. Diagnosis was also confirmed by histopathology. The most frequently encountered follicular structures were larger than typical follicles (56/338, 16...

In this issue of BJOG, Kapur and colleagues call for all European women to undergo screening for gestational diabetes (GDM) as recommended by FIGO (Kapur et al., BJOG 2017 XX). They rightly note the adverse fetal, neonatal, and maternal effects of GDM as well as possible downstream implications for the mother and child. Their recommendations echo those of several leading organizations including FIGO. However, despite these recommendations, some European countries, communities, hospitals and clinicians do not screen all women for GDM...

BACKGROUND: D-transposition of the great arteries (D-TGA) is one of the most common critical neonatal heart defects. Although there are clinical advantages to a prenatal diagnosis, D-TGA has had low prenatal detection internationally. Recent obstetrical ultrasound guidelines incorporating screening of cardiac outflows may improve prenatal detection of D-TGA. We sought to evaluate trends in the prenatal detection of D-TGA with/without ventricular septal defect (VSD) in Alberta over the past 13 years, examining the potential impact of enhanced ultrasound guidelines in 2009-2010 and 2013 and factors impacting detection...

BACKGROUND: Coarctation of the aorta (CoA) is difficult to diagnose by fetal echocardiogram (F-Echo), often requiring multiple F-Echos during gestation and neonatal echocardiograms (N-Echos) after birth. Furthermore, CoA is the most common ductal-dependent lesion missed on routine physical exam. OBJECTIVES: We sought to determine the most cost-effective diagnostic approach in caring for infants in whom an initial F-Echo is concerning for CoA. METHODS: Four paradigms for management after initial F-Echo could not rule out CoA were compared, with a single paradigm involving additional F-Echos: (1) multiple F-Echos for diagnostic clarity and performance of N-Echo on neonates with remaining high suspicion for CoA on F-Echos (prenatal-multiple), (2) no further F-Echo and performance of N-Echo on neonates with high suspicion for CoA on initial F-Echo (postnatal-selective), (3) no further F-Echo and performance of N-Echo on all neonates (postnatal-all), and (4) no further F-Echo or N-Echo with reliance on routine physical exam to identify afflicted infants (postnatal-none)...

OBJECTIVE: A fine structure of the corpus callosum (CC), consisting of radial lines, is seen in historical anatomical atlases as far back as that of Vicq d'Azyr (1786). This study examines a similar pattern observed in vivo using high-resolution MR images at 7 T. METHODS: 8 healthy subjects were examined with 7.0-T MRI. Anatomical images were collected with a gradient echo scan with 0.5-mm isotropic resolution, which were rated for visibility of the radial pattern...

OBJECTIVE: Prenatal congenital heart disease classification system specify critical d-TGA with restriction of the foramen ovale (which requires Rashkind procedure) and planned d-TGA. However, current prenatal diagnostic criteria for post-delivery foramen ovale (FO) restriction in d-TGA are inadequate, resulting in a high false negative rate. We aim to find an echocardiographic features to predict the need for Rashkind procedure. METHODS: 98 patients from 2 European centers diagnosed prenatally with fetal d-TGA from 2006 to 2013 were analyzed and two groups were compared: 1) those in which the Rashkind procedure was performed within the first 24 hours of life; and 2) those who did not undergo a Rashkind procedure before cardiac surgery...

BACKGROUND: The fetal heart at term is exposed to an increase in hemodynamic work as a consequence of fetal growth, increased circulating volume, and alteration in loading patterns due to maturational changes in fetoplacental circulation. The extent to which these cardiovascular changes influence human fetal and neonatal cardiac adaptation has not been fully elucidated. The aim of this study was to evaluate perinatal cardiovascular changes in ventricular geometry and myocardial performance in normal term fetuses...

Maternal diabetes has teratogenic effects on the evolution of the fetal cardiovascular system; as a consequence, cardiovascular malformations are the most common anomalies in infants of diabetic mothers. The present study focuses on the association of all types of diabetes in mothers with the incidence of congenital cardiovascular malformations in their infants. In this retrospective case-control study performed between the years 2008 and 2010, 35 infants of diabetic mothers were selected as a case group, and another 35 infants of mothers with normal blood glucose levels were selected as a control group...

BACKGROUND: Magnetic resonance imaging (MRI) studies have consistently demonstrated disproportionately smaller corpus callosa in individuals with a history of prenatal alcohol exposure (PAE) but have not previously examined the feasibility of detecting this effect in infants. Tissue segmentation of the newborn brain is challenging because analysis techniques developed for the adult brain are not directly transferable, and segmentation for cerebral morphometry is difficult in neonates, due to the latter's incomplete myelination...

PURPOSE: To present a method for spatiotemporal alignment of in-utero magnetic resonance imaging (MRI) time series acquired during maternal hyperoxia for enabling improved quantitative tracking of blood oxygen level-dependent (BOLD) signal changes that characterize oxygen transport through the placenta to fetal organs. MATERIALS AND METHODS: The proposed pipeline for spatiotemporal alignment of images acquired with a single-shot gradient echo echo-planar imaging includes 1) signal nonuniformity correction, 2) intravolume motion correction based on nonrigid registration, 3) correction of motion and nonrigid deformations across volumes, and 4) detection of the outlier volumes to be discarded from subsequent analysis...

FOXC1 loss contributes to Dandy-Walker malformation (DWM), a common human cerebellar malformation. Previously, we found that complete Foxc1 loss leads to aberrations in proliferation, neuronal differentiation and migration in the embryonic mouse cerebellum (Haldipur et al., 2014). We now demonstrate that hypomorphic Foxc1 mutant mice have granule and Purkinje cell abnormalities causing subsequent disruptions in postnatal cerebellar foliation and lamination. Particularly striking is the presence of a partially formed posterior lobule which echoes the posterior vermis DW 'tail sign' observed in human imaging studies...

PURPOSE: The characteristics of fetal thyroid on magnetic resonance (MR) imaging, including normal thyroid and disorders other than goiter have not been fully evaluated. Our aim was to assess fetal thyroid using three dimensional (3D) gradient echo (GRE) T1-weighted MR imaging and to examine the usefulness of this modality. MATERIALS AND METHODS: The study included 27 3D GRE T1-weighted images from 26 fetuses. The largest possible region of interest (ROI) within the thyroid at the slice level depicting the thyroid was manually defined and three circular ROIs on neck muscle were manually defined on the image slices showing the highest signal intensity (SI) of the thyroid...

OBJECTIVE: Fetuses exposed to anti-SSA (Sjögren's) antibodies are at risk of developing irreversible complete atrioventricular block (CAVB), resulting in death or permanent cardiac pacing. Anti-inflammatory treatment during the transition period from normal heart rhythm (fetal heart rhythm (FHR)) to CAVB (emergent CAVB) can restore sinus rhythm, but detection of emergent CAVB is challenging, because it can develop in ⩽24 h. We tested the feasibility of a new technique that relies on home FHR monitoring by the mother, to surveil for emergent CAVB...

BACKGROUND: Prenatal diagnosis of complex congenital heart disease (CHD) has been shown to improve newborn outcomes. The rate of prenatal diagnosis and access to fetal echocardiography vary widely across the United States. INTRODUCTION: A clinical fetal tele-echo service was established at King's Daughters Medical Center (KDMC) in Ashland, KY, a region in eastern Kentucky that is 3 h from the nearest congenital heart surgeon. The aim of this study was to determine if fetal tele-echo utilizing local sonographers at a small regional hospital can accurately and efficiently identify fetuses with complex CHD...
