| Magnifying Narrow Band Imaging (NBI) | Blue light (415 nm) and green light (540 nm) are transmitted. Typically, an option with a white-light endoscope with ability to change to NBI. Can magnify 80x and identify vascular pattern of GI mucosa. |
| Endocytoscopy | Magnification of mucosa to 50 μm in depth |
| Laser-induced fluorescence spectroscopy | Low power laser used for high-magnification and high-resolution imaging |
| Auto-florescent Endoscopy | Detection of tissue based on natural fluorescence after excited by light |
| White light Endoscopy | Standard definition or high-definition images taken from endoscope when shining standard endoscope light |
