U.S. researchers have used stimulated Raman scattering microscopy to distinguish healthy tissue from tumors in the brains of live mice. The technique uses a noninvasive laser to generate a signal from tissue that is used to develop images of living tissue in the brain. The study, published in Science Translational Medicine, also showed that SRS and H&E staining are similarly accurate, but SRS offers benefits H&E doesn't such as real-time data that could be used during surgery to see the margins of a tumor.
