In vivo Raman spectroscopy reveals biochemical composition of the esophageal tissue in pediatric eosinophilic esophagitis.

Real-time intra-endoscopy Raman spectroscopy is an effective method for identifying spectral markers reflective of the esophageal biochemical composition in children with EoE. This technique may aid in the diagnosis and monitoring of EoE and help to elucidate EoE pathogenesis.
