How to Take High-Quality Images (H&N)

With advancements in technology such as narrowband imaging (NBI) and blue laser imaging (BLI), known as image-enhanced endoscopy (IEE), and improvements in magnified endoscopy, numerous cases of squamous cell carcinoma are now being detected through gastrointestinal endoscopy. In the detection and characterization of squamous cell carcinoma, NBI magnification (M-NBI) is significantly superior to white light endoscopy (WLE), making M-NBI an essential tool in daily clinical practice [1, 2].
