Image of the colon acquired by capsule endoscopy. Capsule endoscopy is a medical procedure used to record internal images of the gastrointestinal tract for use in disease diagnosis. Newer developments are also able to take biopsies and release medication at specific locations of the entire gastrointestinal tract. [1]
An endoscopy is a procedure used in medicine to look inside the body. [1] The endoscopy procedure uses an endoscope to examine the interior of a hollow organ or cavity of the body. Unlike many other medical imaging techniques, endoscopes are inserted directly into the organ. There are many types of endoscopies.
Chromoendoscopy. Chromoendoscopy using Lugol's iodine in the esophagus. The image on the left uses regular white light endoscopy. The image on the right stains with Lugol's iodine, and identifies a squamous cell carcinoma, which does not pick up the stain. Chromoendoscopy is a medical procedure wherein dyes (often the same stains used in ...
D019160.

It can be used to visualize the walls of these organs, or to look at adjacent structures.
