A critical analysis of the effect of view mode and frame rate on reading time and lesion detection during capsule endoscopy.

Background And Aim: Factors influencing reading time and detection of lesions include the view mode (VM) and frame rate (FR) applied during reading of small bowel capsule endoscopy images. The aims of this study were to examine the impact of VM and FR on reading time and lesion detection using a standardized, single-type lesion model.

Methods: A selected video clip containing a known number of positive images (n = 60) of small bowel angioectasias was read using nine different combinations of VM and FR (VM1, VM2, and VM4 × FR10, FR15, and FR25) in randomized order by six capsule endoscopists.
