Endoscopic Raman Spectroscopy for Molecular Fingerprinting of Gastric Cancer: Principle to Implementation

Figure 7

Comparison of mean near-infrared Raman spectra of 70 normal stomach samples, (a) 18 intestinal-type adenocarcinomas and 12 diffuse-type adenocarcinomas. (b) Difference spectra were calculated from the mean Raman spectra among the three gastric tissue types (adopted from Teh et al. Br J Surg 2010; 97: 550–557) [42].
