ISUOG's Visual Encyclopedia (VISUOG) chapter on Cervical Teratomas is open access this December. This month we have a discount code to become an ISUOG member and view VISUOG for an entire year.

The July issue of Ultrasound in Obstetrics & Gynecology includes a systematic review and meta-analysis evaluating perinatal outcome of triplet pregnancies following fetoscopic laser surgery for twin–twin transfusion syndrome, a new study exploring the role of ophthalmic artery Doppler in the prediction of pregnancy complications, a prospective study comparing fetal growth in IVF/ICSI pregnancies following frozen–thawed vs fresh blastocyst transfer and a Delphi study providing revised definitions of the MUSA features of adenomyosis. This issue also includes an Opinion providing an overview of our current understanding of monkeypox infection in pregnancy and recommendations for the management of suspected or confirmed cases.

The June issue of Ultrasound in Obstetrics & Gynecology includes a systematic review and meta-analysis evaluating the diagnostic performance of exome sequencing in fetuses with multisystem malformations, a comprehensive study evaluating the cost-effectiveness of strategies for prevention of preterm birth and a study presenting a new algorithm for stratification of monochorionic twin pregnancies with Type-III sFGR according to fetal death risk. Also in the issue are a nationwide study on postnatal outcome of late-preterm twins in South Korea and an accompanying Editorial on the optimal timing of delivery in twin pregnancies. Finally, in this issue, look out for the newly updated ISUOG Guidelines for the performance of the routine mid-trimester fetal scan and an Opinion providing recommendations for fetal cardiac imaging in patients with degraded acoustic windows.

To mark International Cesarean Awareness Month, the April issue of Ultrasound in Obstetrics & Gynecology includes a series of research papers and expert opinions on the topics of abnormally adherent placenta and Cesarean scar pregnancy. The issue also includes a study investigating predictors of fetal cerebral ischemic injury in monochorionic twin pregnancy complicated by spontaneous single intrauterine demise, a large prospective study reporting ophthalmic artery Doppler findings in non-hypertensive pregnancies with small-for-gestational-age or growth-restricted fetus, a multicenter study on the use of clinical phenotypes of small-for-gestational age for risk stratification and a short report demonstrating the positive impact of vaccination on maternal outcome during the Omicron wave of the COVID-19 pandemic.

The March issue of Ultrasound in Obstetrics & Gynecology includes a study validating a novel artificial intelligence tool for detecting CNS abnormalities and a study evaluating fetal growth patterns in monochorionic twin pregnancies complicated by Type-III selective fetal growth restriction. To coincide with Endometriosis Awareness Month, this issue also features a large prospective multicenter study evaluating the accuracy of ultrasound for detection of ovarian and deep endometriosis using #Enzian classification. Also, look out for the recently accepted State-of-the-Art Review on the strengths and limitations of diagnostic tools for endometriosis by an international group of experts in the field of endometriosis research.

The January issue of Ultrasound in Obstetrics & Gynecology is completely free to read! The issue includes a systematic review evaluating the diagnostic accuracy of first-trimester ultrasound examination in the detection of fetal cardiac abnormalities, a study reporting on clinical experience with non-invasive prenatal screening for single-gene disorders, a study developing and validating a model for prediction of placental dysfunction-related stillbirth from maternal factors, fetal weight and uterine artery Doppler at mid-gestation, an analysis of 13,062 SARS-CoV-2-positive pregnancies evaluating comorbidities and social vulnerability as risk factors of maternal death in Mexico, and a prospective study assessing first-trimester screening for placenta accreta spectrum in women with prior Cesarean delivery using transvaginal ultrasound assessment of the lower uterine segment scar.

The August issue of Ultrasound in Obstetrics & Gynecology includes an updated cohort study and meta-analysis on cell-free DNA testing in screening for trisomies in twins, a study longitudinally evaluating motor function in prenatally vs postnatally repaired open neural tube defect cases, a study on cervical electrical impedance spectroscopy to predict spontaneous preterm delivery in asymptomatic women, a study on the association between vaginal birth after Cesarean section and levator ani muscle avulsion, and newly updated ISUOG Practice Guidelines on the use of Doppler velocimetry in obstetrics.

Read the newly updated ISUOG Practice Guidelines on how to perform Doppler ultrasonography of the fetoplacental circulation.

This is a Practice Guideline on how to perform Doppler ultrasonography of the fetoplacental circulation. The aim is to describe pulsed Doppler ultrasound and its different modalities: spectral Doppler, color flow mapping and power Doppler, which are commonly used to study the maternal–fetal circulation.

The November issue of Ultrasound in Obstetrics & Gynecology includes a study on a new approach for estimating the risk of miscarriage after chorionic villus sampling, a study on the trend in ventricle size during pregnancy and its use for prediction of ventriculoperitoneal shunt in fetal open neural tube defect, a study on ophthalmic artery Doppler in the prediction of pre-eclampsia at 35–37 weeks’ gestation, a study and accompanying video abstract on follow-up ultrasound in second-trimester low-positioned anterior and posterior placentae, and a study finding that transvaginal sonography accurately measures lesion-to-anal-verge distance in women with deep endometriosis of the rectosigmoid.
