<b><i>Introduction:</i></b> The purpose was to compare thymus size measured during second trimester screening of fetuses who were subsequently small for gestational age at birth (weight below 10th percentile, SGA group) with normal weight (control group). We hypothesized that measuring the fetal thymic-thoracic ratio (TT-ratio) might help predict low weight. <b><i>Methods:</i></b> Using three-vessel view echocardiograms from our archives, we...

Abstract Objective To compare the adrenal gland size of fetal growth restricted (FGR) and normal control fetuses. Study design In this prospective study 63 FGR fetuses 343 controls was measured between 20 41 weeks gestation.
