“…In conclusion, MRI‐EFW applied to a population with a high prevalence of macrosomic fetuses performed significantly better than US‐EFW in the prediction of large‐for‐dates neonates, when assessment was performed both immediately prior to and remote from delivery. More importantly, and unlike previous studies evaluating MRI‐EFW, the described method is quite simple, reproducible and therefore very promising for future clinical implementation. MRI‐EFW also seems promising in twin pregnancy.…”

“…A more accurate method of EFW could produce better outcomes by restricting interventions such as induction of labour and caesarean section to those fetuses at greatest risk of suspected macrosomia. Some publications have already demonstrated that MRI-derived EFW close to delivery is more accurate than US, with a precision superior to that of US using birth weight as a golden standard,14–23 and a recent meta-analysis has confirmed this promising accuracy 24…”

IntroductionMacrosomia refers to growth beyond a specific threshold, regardless of gestational age. These fetuses are also frequently referred to as large for gestational age (LGA). Various cut-offs have been used but for research purposes, a cut-off above the 95th centile for birth weight is often preferred because it defines 90% of the population as normal weight. The use of centiles, rather than estimated weights, also accommodates preterm macrosomic infants, although most of the complications, maternal and fetal, arise during the delivery of large babies at term. This means that accurate identification of LGA fetuses (≥95th centile) may play an important role in guiding obstetric interventions, such as induction of labour or caesarean section. Traditionally, identification of fetuses suspected of macrosomia has been based on biometric measurements using two-dimensional (2D) ultrasound (US), yet this method is rather sub-optimal. We present a protocol (V.2.1, date 19 May 2016) for the estimation of fetal weight (EFW) by MRI to PREdict neonatal MACROsomia (PREMACRO study), which is a prospective observational clinical study designed to determine whether MRI at 36 + 0 to 36 + 6 weeks of gestation, as compared with 2D US, can improve the identification of LGA neonates ≥95th centile.Methods and analysisAll eligible women attending the 36-week clinic will be invited to participate in the screening study for LGA fetuses ≥95th centile and will undergo US-EFW and MRI-EFW within minutes of each other. From these estimations, a centile will be derived which will be compared with the centile of birth weight used as the gold standard. Besides birth weight, other pregnancy and neonatal outcomes will be collected and analysed. The first enrolment for the study was in May 2016. As of September 2018, 2004 women have been screened and recruited to the study. The study is due to end in April 2019.Ethics and disseminationThe study will be conducted in accordance with the International Conference on Harmonisation for good clinical practice and the appropriate regulatory requirement(s). A favourable ethical opinion was obtained from the Ethics Committee of the University Hospital Brugmann, reference number CE2016/44. Results will be published in peer-reviewed journals and disseminated at international conferences.Trial registration numberNCT02713568.

“…The first advance was the progression from a manual technique for the assessment of FBV to a computer‐aided semiautomatic technique, which reduced the measurements times from 30 minutes down to 5 minutes but without compromising accuracy . We also showed that the number of MRI images used for the planimetric technique did not significantly affect the fetal weight estimations and that the semiautomatic technique for FBV is highly reproducible with interobserver and intraobserver agreement and intraclass coefficients (ICCs) of 0.99 and 0.98, respectively . This level of agreement was also seen when using the manual technique with almost identical ICCs .…”

Extremes of fetal growth can increase adverse pregnancy outcomes, and this is equally applicable to single and multiple gestations. Traditionally, these cases have been identified using simple two‐dimensional ultrasound which is quite limited by its low precision. Magnetic resonance imaging (MRI) has now been used for many years in obstetrics, mainly as an adjunct to ultrasound for congenital abnormalities and increasingly as part of the post‐mortem examination. However, MRI can also be used to accurately assess fetal weight as first demonstrated by Baker et al in 1994, using body volumes rather than standard biometric measurements. This publication was followed by several others, all of which confirmed the superiority of MRI; however, despite this initial promise, the technique has never been successfully integrated into clinical practice. In this review, we provide an overview of the literature, detail the various techniques and formulas currently available, discuss the applicability to specific high‐risk groups and present our vision for the future of MRI within clinical obstetrics.
