Abstract: A method and an apparatus for discriminating a cardiac tissue using Raman scattering are provided which enable a noninvasive discrimination of the cardiac tissue to be accurately performed. The discrimination method includes: a step of irradiating a sample containing a cardiac tissue with excitation light; a step of detecting Raman scattering light from the sample; an analysis step of analyzing the detected Raman scattering light by a multivariate analysis using as an index, Raman scattering spectra which are specific to at least a living myocardial tissue, a necrotic myocardial tissue, a granulation tissue and a fibrotic tissue, respectively; and a step of discriminating the cardiac tissue in accordance with analysis results obtained in the analysis step.
