To develop a deep learning framework for improving spatial metabolite distribution predictions in mass spectrometry imaging.
Introduced the DeepPathMetabol (DPM) framework using optimal transport theory.
Utilized adjacent tissue section data to predict metabolite distributions in MSI sections.
Compared performance against conventional methods like Euclidean metrics and kernel-based metrics.
DPM achieved superior alignment and prediction accuracy compared to conventional methods.
Enhanced the resolution of mass spectrometry imaging without high costs.
Demonstrated potential applicability to spatial transcriptomics.
