Abstract
We report a novel simultaneous fingerprint (FP) and high-wavenumber (HW) fiber-optic Raman spectroscopy developed for in vivo diagnosis of intestinal metaplasia (IM) in the stomach under wide-field endoscopic imaging. The FP/HW Raman endoscopy technique was performed to differentiate IM from normal tissues with sensitivity of 89% and specificity of 83%. This study shows the great potential of the FP/HW Raman endoscopic technique for early diagnosis of non-neoplastic gastric disease in vivo during routine endoscopic examination.
