The mean GA at first MRI was 28.0 ± 2.1 wks and at the second 33.2 ± 1.3
wks. The mean GA in controls was 30.7 ± 4.2 wks. At 28 weeks CDH fetuses
displayed abnormal maturation grading (p<0.003) and fissure
depth (p<0.05). By 33 wks, the brain grading indices were
still abnormal (p<0.01), but fissure depth measurements were
in the normal range (p>0.05). Also, the extra-axial fluid
and the ventricular volume were increased (resp. p 0.0054 and p 0.0243).
There was no difference in white matter or cerebellum volume
(p>0.05).
