BACKGROUND: Zika virus has spread through the Americas and the Caribbean since early 2015 and was rapidly declared a Public Health Emergency of International Concern by WHO because of the potential association with fetal anomalies. We analysed fetal and maternal fluids and tissues in fetuses with confirmed Zika virus infection prospectively monitored in Martinique, a French Caribbean island. METHODS: Since the beginning of the Zika virus outbreak in Martinique, all pregnant women undergo monthly fetal ultrasound examination surveillance...

BACKGROUND: Pentalogy of Cantrell (POC) is an extremely rare and complex congenital anomaly. Ultrasound is a valuable, safe, nonionizing, cost effective, widely available, and easily reproducible imaging tool and is indispensible in the diagnosis of POC. Despite the rarity of POC, it is imperative for a radiologist to be aware of its wide spectrum of presentation on ultrasound in first trimester of gestation. Most reported cases in literature till now have been sporadic. In this paper, we aimed to report for the first time in literature, a recurrent case of POC detected in the first trimester in a mother whose previous pregnancy also was terminated in the second trimester medically due to the ultrasound diagnosis of POC...

BACKGROUND: The neonatal development stage of the cerebellum in rats is equivalent to a human foetus in the third trimester of pregnancy. In this stage, cell proliferation, migration, differentiation, and synaptogenesis occur. Clinical and experimental findings have shown that ethanol exposure during brain development causes a variety of disruptions to the brain, including neurogenesis depression, delayed neuronal migration, changes in neurotransmitter synthesis, and neuronal depletion...

BACKGROUND: Prenatal alcohol exposure leads to impaired fetal growth, brain development, and stillbirth. Placental impairment likely contributes to these adverse outcomes, but the mechanisms and specific vasoactive effects of alcohol that links altered placental function to impaired fetal development remain areas of active research. OBJECTIVE: Recently, we developed magnetic resonance imaging techniques in nonhuman primates to characterize placental blood oxygenation through measurements of T2* and perfusion using dynamic contrast-enhanced magnetic resonance imaging...

Women of reproductive age with pelvic pain, vaginal bleeding, and a positive pregnancy test often require evaluation with pelvic ultrasound. In these situations, the primary role of pelvic ultrasound is to differentiate an ectopic pregnancy from either a normal or abnormal intrauterine pregnancy. While an accurately performed and interpreted pelvic ultrasound results in rapid diagnosis and management, numerous diagnostic pitfalls can lead to negative outcomes. Therefore, familiarity with the appropriate laboratory tests, sonographic technique, and imaging features of ectopic pregnancy is essential for all radiologists...

Congenital heart disease (CHD) occurs in 4-13 per 1000 births in the United States. While many risk factors for CHD have been identified, more than 90% of cases occur in low-risk patients. Guidelines for fetal cardiac screening during the second trimester anatomy ultrasound have been developed by the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) in order to improve antenatal detection rates and to standardize the fetal cardiac screening examination. Patients found to be at increased risk of CHD because of risk factors or an abnormal screening examination should be referred for second trimester fetal echocardiography...

OBJECTIVES: To predict likelihood of spontaneous resolution during fetal life and postnatal outcome of fetal megacystis, diagnosed in all trimesters in pregnancy. METHODS: This was a national retrospective cohort study. Fetal megacystis was defined in the first trimester as a longitudinal bladder diameter (LBD) ≥ 7 mm, and in the 2(nd) and 3(rd) trimester as an enlarged bladder failing to empty during the entire extended ultrasound (US) examination. LBD and GA at resolution were investigated as of likelihood of resolution and of postnatal outcome, respectively...

Rudimentary horn could be a rare congenital uterine anomalies result from incomplete fusion of the two Müllerian ducts throughout embryo-genesis. Pregnancy in an exceedingly rudimentary horn is rare and typically terminates in rupture throughout the late of first or second trimester of pregnancy. We tend to present a rare case of a gravida within the trimester (31 weeks) presented with complain of abdominal pain, nausea, and vomit for 3 days. On presentation, the patient was pale and irritable. Ultrasound scan showed fetus at (30 weeks) with cardiac activity...

Ectopic pregnancy is commonly seen as a differential diagnosis of first-trimester vaginal bleeding. Often the diagnosis is made based on a combination of exam findings, transvaginal ultrasound, and a positive pregnancy test. Our case describes a patient with a history of ectopic pregnancy treated with methotrexate and serial human chorionic gonadotropin measurements that were decreasing appropriately. At the time of evaluation, her urine pregnancy test was negative; however, she was confirmed to have a ruptured tubal ectopic pregnancy...

In this paper we propose a new methodology to support the physician both to identify automatically the nuchal region and to obtain a correct thickness measurement of the nuchal translucency. The thickness of the nuchal translucency is one of the main markers for screening of chromosomal defects such as trisomy 13, 18 and 21. Its measurement is performed during ultrasound scanning in the first trimester of pregnancy. The proposed methodology is mainly based on wavelet and multi resolution analysis. The performance of our method was analysed on 382 random frames, representing mid-sagittal sections, uniformly extracted from real clinical ultrasound videos of 12 patients...

Zika virus is an emerging mosquito-borne (Aedes genus) arbovirus of the Flaviviridae family. Following epidemics in Micronesia and French Polynesia during the past decade, more recent Zika virus infection outbreaks were first reported in South America as early as May 2013 and spread to now 50 countries throughout the Americas. Although no other flavivirus has previously been known to cause major fetal malformations following perinatal infection, reports of a causal link between Zika virus and microcephaly, brain and ocular malformations, and fetal loss emerged from hard-hit regions of Brazil by October 2015...

Use of non-ionizing radiation (NIR) for diagnostic purposes allows non-invasive assessment of the structure and function of the human body and is widely employed in medical care. ICNIRP has published previous statements about the protection of patients during medical magnetic resonance imaging (MRI), but diagnostic methods using other forms of NIR have not been considered. This statement reviews the range of diagnostic NIR devices currently used in clinical settings; documents the relevant regulations and policies covering patients and health care workers; reviews the evidence around potential health risks to patients and health care workers exposed to diagnostic NIR; and identifies situations of high NIR exposure from diagnostic devices in which patients or health care workers might not be adequately protected by current regulations...

BACKGROUND: Missed abortion (MA) can be managed expectantly, medically or surgically. Surgical management has been performed safely in the office setting by suction dilation and curettage (D&C). Prior studies suggest that intraoperative ultrasound guidance (USG) may reduce complications for first-trimester therapeutic abortion. The aim of this study was to evaluate the safety of office D&C for MA using real-time USG. METHODS: This retrospective cohort study included 255 patients who underwent office D&C under USG for first trimester MA at a single university-affiliated fertility clinic during January 2011-December 2013...

BACKGROUND: The term "cesarean scar pregnancy" (CSP) refers to placental implantation within the scar of a prior cesarean delivery. The rising numbers of cesarean deliveries in the last decades have lead to an increased incidence of CSP. Complications of CSP include: morbidly adherent placenta, uterine rupture, severe hemorrhage, and preterm labor. It is suspected that CSPs implanted within a dehiscent scar ("niche") behave differently compared to those implanted on top of a well healed scar...

The introduction of cell-free DNA (cfDNA) screening for aneuploidy into obstetric practice in 2011 revolutionized the strategies utilized for prenatal testing. The purpose of this document is to review the current data on the role of ultrasound in women who have undergone or are considering cfDNA screening. The following are SMFM recommendations: 1) in women who have already received a negative cfDNA screen, ultrasound at 11-14 weeks of gestation solely for the purpose of NT measurement (CPT code 76813) is not recommended (GRADE 1B); 2) we recommend that diagnostic testing should not be recommended to patients solely for the indication of an isolated soft marker in the setting of a negative cfDNA screen (GRADE 2B); 3) in women with an isolated soft marker without other clinical implications (ie, choroid plexus cyst or echogenic intracardiac focus) and a negative cfDNA screen, we recommend describing the finding as "not clinically significant" or as a "normal variant" (GRADE 2B); 4) in women with an isolated soft marker that has no other clinical implication (ie, choroid plexus cyst or echogenic intracardiac focus) and a negative first or second trimester screening result, we recommend describing the finding as "not clinically significant" or as a "normal variant" (GRADE 2B); 5) we recommend that all women in whom a structural abnormality is identified by ultrasound should be offered diagnostic testing with chromosomal microarray (GRADE 1A); 6) we recommend against routine screening for microdeletions with cfDNA (GRADE 1B)...
