Objective: The aim of the study was to evaluate feasibility and reproducibility of fetal transcerebellar diameter measurement during second and third trimester ultrasound mass screening by junior and senior physicians. Materials and methods: A monocentric prospective study was conducted at the tertiary care teaching hospital in Lyon, including patients undergoing their second or third trimester planned ultrasound exam. For each patient, a resident and a senior practitioner measured each fetal transcerebellar diameter, during a blinded experiment, according to the transcerebellar plane described by the International Society of Ultrasound in Obstetrics and Gynecology. Images have been scored on 4 criteria. The inter-observer variability for transcerebellar diameter and image quality was assessed using an intra-class correlation coefficient. Image quality has been analyzed according to pregnancy term and to fetal presentation. Results: Sixty-six patients were included, 44 patients before and 22 patients after 30 weeks. Inter-observer variability of transcerebellar diameter measurement was 0.4%. Inter-observer variability of image quality was 13.5%. Image quality was not significantly different between seniors and residents (P = 0.06). Gestational age and fetal presentation did not affect significantly image quality (P = 0.42) and (P = 0.64) respectively. Conclusion: Transcerebellar diameter measurement during mass screening is simple and reliable. Posterior fossa abnormalities can be explored through its measurement. © 2015 Elsevier Masson SAS.

To establish a reference chart for estimated fetal weight (EFW) using the Hadlock formula based on recent biometric data (2012-2013). A prospective multicentric longitudinal study was carried out. Biometric parameters as the head circumference (HC), abdominal circumference (AC) and the femur length were measured in multiple areas of France from January 2012 until December 2013. EFW was calculated using the predictive formula of Hadlock using three parameters. The accurate gestational age was the main inclusion criteria calculated in weeks of gestation (WG). A polynomial regression approach was used to calculate the mean and standard deviation for every WG adjusted to raw data. Centiles of EFW were calculated from the z score that corresponds to the gˆˆ'1.88, gˆˆ'1.28, 0, +1.28, +1.88 respectively for the 3rd, 10th, 50th, 90th, et 97th percentile in order to establish a new chart of EFW. Measurements were obtained for 33,143 fetus between 17 et 38 WG. Reference charts with the 3rd, 10th, 50th, 90th et 97th percentiles were presented. The reference Chart 2014 is an in utero chart for EFW based on ultrasound measurements data reliable and homogenous from a sample of 33,143 fetus of a general population. It offers a tool to use in routine ultrasound examination for the survey of the fetal growth and to diagnose fetus that are small for gestational age or presenting a restriction in growth. © 2015 Elsevier Masson SAS.
