Narrow-band imaging (NBI) flexible cystoscopy


NBI is an optical image
enhancement technology in which the
narrow bandwidth of light is strongly
absorbed by haemoglobin and penetrates only
the surface of tissue, increasing the visibility
of capillaries and other delicate tissue surface
structures by enhancing contrast between
the two.

Examples of the differences between tumours visualized with WLI cystoscopy (upper) and NBI
cystoscopy (down).
