etermining normal fetal size and weight is one of the key points in assessing its development and normal course of pregnancy. With intrauterine growth restriction, as well as with macrosomia, the frequency of obstetric and neonatal risks increases significantly. Estimated fetal weight is one of the main factors that affects pregnancy management, timing and method of delivery. Currently, in obstetric practice, two main approaches are used to determine fetal weight: clinical and ultrasound. However, the accuracy of these methods in some cases is quite limited. Magnetic resonance imaging (MRI) has been used in obstetrics for many years, mainly as an additional to ultrasound for congenital anomalies. MRI can potentially be used as the most accurate modality for determining fetal weight. However, this modality has not found wide application due to the availability and cost. In this review, we describe in detail various methods and formulas, discuss the applicability of approaches to specific groups at highest risk and present our vision for the future of MRI in obstetric practice.


Keywords: estimated fetal weight, prenatal diagnosis, fetal MRI, macrosomia, fetal growth restriction.
