Mass Spectrometry Imaging
overall review score: 4.4
⭐⭐⭐⭐⭐
score is between 0 and 5
Mass spectrometry imaging (MSI) is an analytical technique that enables the spatial visualization of molecular distributions within biological tissues and samples. By combining mass spectrometry with imaging methods, MSI provides detailed maps of various compounds—such as lipids, proteins, metabolites, and drugs—without requiring labels or prior knowledge. This technique is widely used in biomedical research, pharmacology, and diagnostics to study tissue heterogeneity and molecular pathology.
