Quantitative assessment of brain sparing effect in fetal growth restriction: structural evidence from fetal MRI
Objective To differentiate brain-sparing patterns in fetal growth restriction (FGR) versus small-for-gestational-age (SGA) fetuses using MRI volumetry. Methods This retrospective study analyzed whole-body MRI data from 378 fetuses (28–40 weeks’ gestation) collected between 2018 and 2025, comprising 308 normal controls,...
