Figure 3From: Back-to-Back Comparison of Auto-Fluorescence Imaging (AFI) Versus High Resolution White Light Colonoscopy for Adenoma Detection Procedural time of HRE and AFI. The procedural time of HRE (144.5 ± 8.8 seconds) was significantly shorter than that of AFI in all participants (267.0 ± 20.8 seconds; p < 0.05) (A). An increase in the procedural time for the AFI examination was revealed in either experienced endoscopists (B) or less-experienced endoscopists (C).Back to article page
