Comparison of Narrowband Imaging with Autofluorescence Imaging for Endoscopic Visualization of Superficial Squamous Cell Carcinoma Lesions of the Esophagus
Figure 1
Squamous cell carcinoma (SCC) in middle esophagus (mucosal invasion: carcinoma in situ; depressed type; 30 mm). (a) Narrowband imaging (NBI) endoscopy clearly revealed demarcated area brownish in color with NBI image visualization quality rated as excellent for delineating entire lesion margin circumference. (b) Autofluorescence imaging (AFI) endoscopy clearly revealed demarcated area magenta in color with AFI image visualization quality rated as excellent for delineating entire lesion margin circumference.
