Magnetic resonance fetal right lung volumetry and its efficacy in predicting postnatal short-term outcomes of congenital left-sided diaphragmatic hernia.

摘要: Aim We aimed to investigate whether the ratio of magnetic resonance imaging (MRI)-measured right lung volume (RLV) ultrasonography-estimated bodyweight (RLV/BW) and observed-to-expected (o/e) RLV are diagnostic value in predicting postnatal outcomes left congenital diaphragmatic hernia (CDH). Material Methods We included 32 CDH patients 34 control subjects. Manually outlined fetal areas on MRI were multiplied by slice thickness added determine entire volume. The association between RLV/BW with gestational age controls was examined using regression analysis. o/e compared surviving non-surviving neonates CDH. Results The expected derived formula (mm3) = 1.717 × (gestational weeks)2.82. In controls, nearly constant during third trimester. 27 survivors had a median 10.7 60.0, whereas five 4.3 22.6; differences statistically significant. Conclusion Assessment lungs volumetry is reliable for clinical use. potential predictors CDH.
