Prediction of pulmonary hypoplasia in preterm prelabour rupture of membranes prior to 24+0 weeks of gestation using fetal MRI.

Among 23 fetuses included, 6 had pulmonary hypoplasia.

Earlier PPROM, earlier delivery, and severe oligohydramnios were significantly associated with pulmonary hypoplasia.

A lung-to-liver signal intensity ratio below 1.64 predicted pulmonary hypoplasia with a sensitivity of 100 % and specificity of 83.3 %.
