The MALDI-MSI workflow employed here for the analysis of excised tissue (a) post-MRI consisted of freeze thaw mounting of cryosectioned tissue (b), on tissue digestion for peptide analysis (omitted for lipids) prior to matrix application, and finally generation of MALDI-MSI (c) to enable the mapping and co-registration of peaks of interest found in the corresponding MALDI spectrum (d)
