✦ Synopsis

The effect of the time of the initial scan and the interval between the two scans needed for Rossavik growth model specification was evaluated in 20 normally growing fetuses. Based on systematic and random prediction errors, determined by comparing predicted values to measured values obtained after 27 weeks, menstrual age, optimal results for all parameters studied were obtained with an initial scan at 18 weeks and an interval of 6 weeks between scans. For one-dimensional parameters-head circumference (HC), abdominal circumference (AC), and femur diaphysis

We studied the influence of the interval between the two scans used before 26 weeks' menstrual age to generate individual fetal growth curve standards utilizing the Rossavik growth model: P = c(tIk + '(') (model specification functions previously reported).
