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.

Read the newly updated ISUOG Practice Guidelines on how to perform the routine mid-trimester fetal ultrasound scan.

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 September issue of Ultrasound in Obstetrics & Gynecology includes a study on the impact of crown–rump measurement error on assessment of fetal growth, a study on the safety and efficacy of the Pfizer/BioNTech COVID-19 vaccine in pregnant women, a study presenting reference ranges and calculators for fetal cardiac relative size and geometry parameters, and a study assessing the combination of the Proactive Molecular Risk Classifier for Endometrial cancer (ProMisE) with sonographic and demographic characteristics in the preoperative prediction of recurrence or progression of endometrial cancer.

The June issue of Ultrasound in Obstetrics & Gynecology includes a consensus opinion from the VITA group on terms, definitions and measurements to describe the sonographic features of lymph nodes, a debate on the relative merits of the SMFM and ISUOG guidelines for diagnosing and managing fetal growth restriction, a State-of-the-Art Review on controversies in the management of twin pregnancy, and a RCT on routine third-trimester ultrasound for the detection of small-for-gestational age in low-risk pregnancies.

The focus of this Guideline is to describe the protocol for the diagnostic ultrasound examination that should be performed in any case in which there is an increased risk of central nervous system (CNS) malformation.

The January 30th anniversary special issue of Ultrasound in Obstetrics & Gynecology is completely free to access. The issue includes a number of insightful Opinions from leaders in the field, including Stuart Campbell’s recollections of how ISUOG and the Journal were born, Katia Bilardo’s reflections on how the Society has evolved, Kurt Hecher’s account of how intrauterine surgery has advanced over the last three decades and Roberto Romero’s commentary on the prediction and prevention of preterm birth. Also included are high-impact research papers from influential groups which highlight the breadth of topics in which ultrasound plays an instrumental or supporting role.
