Comparison between NBI-Blue1 (NBI-B1) images and squamous dysplasia with ASD. The dotted vessels were observed at 18 abnormal fluorescence sites with NBI-B1 images, at which 14 (78%) exhibited ASD. The negative dotted vessels among the vascular networks were at 49 abnormal fluorescence sites, at which 48 (98%) were without ASD. There was significant association between the frequency of dotted vessels by NBI-B1 imaging and pathologically confirmed ASD (p=0.002 by Fisher’s exact probability test).
