Distinguishing patients with celiac disease by quantitative analysis of videocapsule endoscopy images
Abstract: Background: Although videocapsule endoscopy images are helpful in the evaluation of celiac disease, their interpretation is subjective. Quantitative disease markers could assist in determining the extent of villous atrophy and response to treatment.Method: Capsule endoscopy images were acquired from celiac patients with small bowel pathology (N=11) and from control patients (N=10). Image resolution was 576×576 pixels in dimension, 256 grayscale levels, and had a 2s−1 frame rate. Pixel brightness and image texture were measured over 10×10 pixel subimages and then averaged for 56×56 subimages per frame. Measurements were obtained at five locations from proximal to distal small intestine in each patient. At each location, measurements were calculated using 200 consecutive image...MedWorm Message: Register for MedMatcha, MedWorm's medical advertising network, and receive $5 free advertising.
