Objective Assessment of Visibility of Colorectal Lesions Using Eye Tracking for New Image-Enhanced Endoscopy Observation.

ABSTRACT:

Background and aim

This study aimed to objectively evaluate colorectal lesion visibility using white-light imaging (WLI), narrow-band imaging (NBI), and texture and color enhancement imaging (TXI) with an eye tracking system.

Methods

Twelve endoscopists assessed 120 images of 30 colorectal lesions (29 adenomas, one sessile serrated lesion) captured using WLI, NBI, TXI mode-1, and TXI mode-2. Eye movements were recorded to analyze the lesion detection ability and time taken. The miss rate (calculated as the ratio of missed lesions from 360 images) and detection time (defined as the time from displaying the image to the start of gaze on lesions) were compared among the four modalities.

Results

The miss rates of WLI, NBI, TXI mode-1, and TXI mode-2 were 16.4%, 6.4%, 11.7
