Artificial intelligence and the analysis of multi-platform metabolomics data for the detection of intrauterine growth restriction.
<h4>Objective</h4>To interrogate the pathogenesis of intrauterine growth restriction (IUGR) and apply Artificial Intelligence (AI) techniques to multi-platform i.e. nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) based metabolomic analysis for the prediction of I...
