Validated criteria for interpretation of volumetric laser endomicroscopy Images of gastroesophageal tissue[12]

Diagnosis	Imaging criteria on volumetric laser endomicroscopy
Squamous epithelium	Layered horizontal architecture
	Absence of glands
Gastric cardia	Vertical pit architecture
	Regular glandular architecture
	Poor image penetration
	Homogeneous scattering
	Regular, broad gastric rugae
Metaplasia	Lack of layered or vertical pit architecture
	Heterogeneous scattering
	Irregular surface
	Atypical glandular structure
