Impaired fetal thymic development in preeclampsia. a Nepean cohort 1: Virtual organ computer-aided analysis calculation of the fetal thymus volume at 26 weeks of gestation, showing three orthogonal planes (left top: transverse, right top: coronal, left down: sagittal) and reconstructed thymus volume (right down). b Dot plot showing fetal thymus volumes in different gestational weeks in both non-preeclamptic (n = 50, black dots) and preeclamptic (n = 50, red dots) groups. Mean ± SD: 2.6 ± 1.3 mL and 1.6 ± 1.2 mL, respectively (p < 0.001, unpaired t-test). c Nepean cohort 2: Fetal thymus diameter measurement: an axial view of the fetal thymus was obtained, within a standard image of the right ventricular outflow tract (RVOT). Then a line was drawn connecting the fetal spine and sternum (I). Fetal thymus diameter was measured as its greatest diameter (II), perpendicular to line I. Sp = spine, S = superior vena cava, A = aorta, P = pulmonary artery. Scale bar = 5 mm. d Dot plot showing fetal thymus diameter in different gestational weeks in both non-preeclamptic (n = 863, black dots) and preeclamptic (n = 24, red dots) groups, adjusted means were 18.3 mm and 16.5 mm, respectively (p < 0.001, unpaired t-test)
