In vivo pilot study into superficial microcirculatory characteristics of colorectal adenomas using novel high-resolution magnifying endoscopy with blue laser imaging

Figure 1 Superficial capillaries in an adenoma and surrounding normal mucosa observed under high-resolution magnifying endoscope with blue-laser imaging, and then identified by Image-pro plus software. A: Blue laser imaging (BLI) observed the surface vessels of adenomas; B: BLI observed normal mucosal surface vessels around the adenoma; C: Image-pro plus identified the blood vessels on the surface of adenoma as red; D: Image-pro plus identified normal mucosal surface blood vessels around the adenoma as red. BLI: Blue-laser imaging.

Figure 2 The green marks represent the blood flow progression in 1/30 s. A: The green mark represents the blood flow position at a certain time; B: The green mark represents the blood flow position after 1/30 s.
