Sections in panel A. were imaged at 50 × 50 µm, and in panel C. (from the left side): at 50 × 50 µm (Leuven), 17 × 17 µm (Münster), 50 × 50 µm (Dresden), and 20 × 20 µm (Münster). The impact of standard normalization on raw MSI images was evaluated using a glioblastoma mouse brain model via four different mass spectrometry platforms: timsTOF fleX MALDI-2 (Leuven, Belgium), timsTOF fleX MALDI-2 (Münster, Germany), MALDI-Q Exactive TM Orbitrap (Münster, Germany), and AP-SMALDI-Q Exactive TM Orbitrap (Dresden, Germany). All datasets were processed using LipidQMap. A . Comparison of raw MSI images of three lipid species - PC 32:0 [M+H] + , SM 40:1;O2 [M+K] + , and Cer 42:2;O2 [M-H 2 O+H] + - before and after normalization using standards PC [D9] 32:0 [M+H] + , LPC [D9] 16:0 [M+K] + , and Cer 30:1;O2 [M-H 2 O+H] + , respectively. B. Quantitative bulk HILIC-MS/MS lipidomics results from LCM-extracted ROIs as indicated in the brightfield brain scan: blue – brain cortex, orange – tumor rim, red – tumor (glioblastoma), green – corpus callosum. C . Cross-platform comparison of PC 32:0 [M+H] + images in raw ( I. ), isobaric-corrected ( II. ), and standard normalized formats ( III. ). Normalization was performed using PC [D9] 32:0 [M+H] + . The qMSI image of PC 32:0 [M+H] + acquired via MALDI-Q Exactive TM Orbitrap (Münster, Germany), contained empty pixel lines, which were corrected using LipidQMap based on the median lipid concentrations of surrounding pixels.
