“…The distinction between hypoplastic and healthy lungs with less than 25 weeks of gestation was less definitive. Terui et al [28] evaluated the signal intensity of fetal lungs using MRI as a predictor of prognosis in fetuses with congenital diaphragmatic hernia. Twelve fetuses with congenital diaphragmatic hernia between 29-37 weeks of gestation were evaluated, and the relationship between lung and spinal fluid signal intensities was calculated using the analysis of the region of interest in T2-weighted images.…”

Objective To assess the applicability of magnetic resonance imaging (MRI) to complement ultrasound in the diagnosis of fetal urinary tract anomalies. Methods This was a retrospective cohort study that included 41 women between 19 weeks and 37 weeks and 6 days of gestation carrying fetuses with malformations of the urinary tract which were initially diagnosed by ultrasound and then referred for MRI. In all cases, the diagnosis was confirmed after birth either through imaging or autopsy. A surface coil was positioned over the abdomen and T2-weighted sequences were obtained in the axial, coronal, and sagittal planes; T1 in at least one plane; and three-dimensional (3-D) TRUFI in fetuses with dilatation of the urinary tract. Results Mean gestational age at the time of MRI examination was 28.21 weeks. The rapid T2 sequences allowed all the anomalies of the fetal urinary tract to be assessed, whereas 3-D TRUFI sequencing proved very useful in evaluating anomalies involving dilatation of the urinary tract. The signs of pulmonary hypoplasia characterized by hypointense signal in the T2-weighted sequences were identified in 13 of the 41 fetuses. Conclusion MRI confirmed and added information to the ultrasound regarding fetal urinary tract anomalies, as well as information related to the other associated malformations, their progress in the prenatal period, and possible postnatal prognosis.

“…The ratio of the lung signal intensity to the spinal fluid signal intensity (L/SF) were significantly larger in survivors compared with deaths (0.82 vs 0.61, P<0.05). This ratio correlated with duration of tracheal intubation (P<0.01) (Terui et al, 2011).…”
