Chemical imaging brings cancer tissue analysis into digital age
Mass spectrometry imaging (MSI) uses technologies that reveal how hundreds or thousands of chemical components are distributed in a tissue sample. Scientists have proposed using MSI to identify tissue types for many years, but until now, no method has been devised to apply such technology to any type of tissue. In this week’s Proceedings of the National Academy of Sciences, researchers at Imperial College London have outlined a recipe for processing MSI data and building a database of tissue types…
