Advanced imaging diagnosis in gastrointestinal endoscopy

The imaging technologies of gastrointestinal endoscopy have gained rapid advancement in recent years as the need of early diagnosis. Image-enhanced endoscopy, including chromoendoscopy, high-definition endoscopy, magnifying endoscopy, and narrow band imaging, are now applied in daily practice. The other emerging technologies, such as autofluorescence imaging, spectroscopy, confocal laser endomicroscopy, optical coherence tomography, endocytoscopy, and molecular imaging, are still under research setting. In the future, an "all-in-one" endoscope integrated several technologies will be developed to accomplish complete diagnosis in one procedure. The advance in molecular imaging will move forward the personalized medicine. The continued development of imaging technology in endoscopy will attain perfection in the diagnosis of gastrointestinal diseases.
