Integrated Endoscopic System Based on Optical Imaging and Hyperspectral Data Analysis for Colorectal Cancer Detection.

Background/aim: Two-dimensional hyperspectral data systems with enhanced area detection and diagnostic abilities are now available in gastrointestinal endoscopy for colorectal cancer. We evaluated a new hyperspectral system for diagnosis of colorectal cancer.

Patients And Methods: A resected-specimen spectrum observation module (stereoscopic macroscope, hyperspectral camera, and xenon lamp) was used to evaluate 21 resected colorectal cancer specimens (ex vivo experiment).
