High resolution 1H NMR spectroscopy is performed to compare amniotic fluid from fetuses with congenital diaphragmatic hernia undergoing temporary tracheal occlusion or its reversal against healthy controls. Principle Component Analyses and Multidimensional Scaling are separately applied in combination with various automated classification techniques for differentiating the complicated pregnancies. Results show that dimensionality reduction methods in combination with automated classifiers when analyzing 1H NMR spectra have a high potential in identifying complicated pregnancies. Thus, it can represent an attractive tool which combined with routine fetal magnetic resonance imaging could help to obtain a more detailed picture of the fetal status.
