Caption: Image A shows DESI mass spectrometry imaging from a surgical sample of a meningioma tumor and an optical image of a stained serial section. The distribution of meningioma cells observed by microscopy correlates with that identified through the DESI analysis. Image B shows the mass spectrum of meningioma region of the tissue section and illustrates the characteristic meningioma lipid profile.
