RATIONALE AND OBJECTIVES: The American Institute of Ultrasound in Medicine (AIUM) recommends that all providers performing ultrasound-guided invasive procedures be competent in a core set of guidance skills common to all ultrasound-guided procedures, including in-plane and out-of-plane needle guidance and needle imaging optimization techniques such as probe translation, rotation, and heel-toe standoff. To allow for the practice and assessment of these core skills, we have created a novel task trainer and set of targeting tasks, and sought to obtain validity evidence in the content and response process domains for this training and assessment system according to the Standards for Educational and Psychological Testing...

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...

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)...

We describe a rare case of heterotopic pregnancy following in vitro fertilization with transferring of two embryos in a 39-year-old woman with previous bilateral salpingectomy. An ultrasound examination was performed on the day before admission showing a vital intrauterine pregnancy and no ectopic pregnancy. The woman was admitted with a ruptured cornual pregnancy at ten weeks of gestation. Laparotomy was performed on vital indication with excision of the ruptured haemorrhagic cornual pregnancy. The intrauterine pregnancy continued uneventfully with obstetric and fetal medicine specialist monitoring...

BACKGROUND: In-utero MRI (iuMRI) has shown promise as an adjunct to ultrasound but the comparative diagnostic performance has been poorly defined. We aimed to assess whether the diagnostic accuracy and confidence of the prenatal diagnosis of fetal brain abnormalities is improved with iuMRI and assess the clinical impact and patient acceptability of iuMRI. METHODS: We did a multicentre, prospective, cohort study in the UK, at 16 fetal medicine centres, of pregnant women aged 16 years or older whose fetus had a brain abnormality detected by ultrasound at a gestational age of 18 weeks or more, had no contraindications to iuMRI, and consented to enter the study...

BACKGROUND: Gastroschisis is the most common major congenital anomaly managed by paediatric surgeons. The significance of certain associated antenatal ultrasound features in determining fetal outcome is under discussion. AIM: The study aims to define if associated antenatal ultrasound features of gastroschisis are useful prognostic markers for fetal outcome. By establishing the significance of features, including extra- and intra-abdominal bowel dilatation, stomach herniation, stomach dilatation, bowel matting, growth restriction, abnormal umbilical artery (UA) Doppler ultrasounds, and abnormal amniotic fluid volume, it is hoped clinicians will have enhanced ability to counsel parents about the likely outcomes for their infant...
