Ultrasound in Obstetrics & Gynecology (UOG) achieved another impressive 6.3 million downloads in 2025. Take a look at the most popular items of 2025 - all of which are open access.
- ISUOG Practice Guidelines (updated): role of ultrasound in twin pregnancy by Khalil et al. This updated practice guideline addresses the role of ultrasound in the care of uncomplicated twin pregnancies and those complicated by twin–twin transfusion syndrome, selective fetal growth restriction (sFGR), twin anemia–polycythemia sequence (TAPS), twin reversed arterial perfusion (TRAP) sequence, conjoined twins and single intrauterine death (IUD). This document also provides guidance on the methods used to determine gestational age and chorionicity as well as screening for abnormalities and the risk of preterm birth.
- How to apply the 20 + 2-planes method for identification of 65 fetal abnormalities during routine second-trimester fetal ultrasound examination by Chudleigh and Cohen-Overbeek for the ISUOG Basic Training Sub-Committee. This how to article provides an overview of the 20 + 2-planes method and details how its correct application during a routine second-trimester fetal ultrasound examination can assist in the identification or exclusion of 65 fetal structural anomalies.
- Routine 36-week scan: diagnosis of fetal abnormalities by Syngelaki et al. The findings of this study provide further support for a routine 36-week anomaly scan, in addition to those performed at 12 weeks and 20 weeks' gestation.
- ISUOG Practice Guidelines: point-of-care ultrasound in obstetrics and gynecology by De Robertis et al. This practice guideline provides recommendations regarding the appropriate use of point-of-care ultrasound (PoCUS) in ob/gyn in various clinical scenarios encountered by different healthcare professionals.
- Addendum to consensus opinion from the International Deep Endometriosis Analysis (IDEA) group: sonographic evaluation of superficial endometriosis by Guerriero et al. This consensus opinion describes a standardised ultrasound protocol for the diagnosis of superficial endometriosis.
- Association between borderline amniotic fluid levels and adverse perinatal outcome: systematic review and meta-analysis by Sgayer et al. This systematic review evaluated adverse perinatal outcomes in low-risk singleton pregnancies with borderline oligohydramnios.
- Application of artificial intelligence to ultrasound imaging for benign gynecological disorders: systematic review by Moro et al. This article focusses on the various applications of artificial intelligence (AI) to gynecological ultrasound imaging, demonstrating that AI models are useful in several benign gynecological conditions and show promise for future clinical translation.
- Transvaginal ultrasound assessment of corpus callosal length in the fetus: multicenter cross-sectional study by Paladini et al. This multicentre study presents growth charts for corpus callosal (CC) length in the fetus, based on transvaginal three-dimensional (3D) ultrasound imaging.
- Transvaginal cervical cerclage: double monofilament modified Wurm vs single braided McDonald technique by Donadono et al. This prospective study reported that in high-risk women with a sonographic short cervical length, placement of a modified Wurm cervical cerclage is associated with a lower rate of preterm birth <32 weeks compared with McDonald cervical cerclage.
- ISUOG/ESGO Consensus Statement on ultrasound-guided biopsy in gynecological oncology by Fischerova et al. This joint consensus statement provides accessible guidance to clinicians to help achieve the best standards of practice in ultrasound-guided biopsy and improve patient outcomes.
