Narrow-band imaging (NBI) is superior to white-light imaging (WLI) in detecting urothelial carcinoma of the bladder, according to a new study from China PLA General Hospital in Beijing, published in Urologic Oncology.

Urothelial carcinoma is a vascular cancer type, and is commonly diagnosed with WLI cystoscopy. Operating in much the same way as WLI, NBI uses modified optical filters to split white light into two bands of 415 nm and 540 nm. These wavelengths are strongly absorbed by hemoglobin, increasing the contrast between the blood vessels of the tumor and those of the submucosa.
