Figure 4From: Capsule endoscopy with flexible spectral imaging color enhancement reduces the bile pigment effect and improves the detectability of small bowel lesions Evaluation of the lesion detection rate according to the bile pigment condition. The lesion detection rate under the conventional CE setting and FICE setting 2 were significantly reduced in the presence of bile pigments in the small bowel (*). On the other hand, the lesion detection rate under FICE setting 1 was not affected by the presence of bile pigments. In the bile-pigment-positive condition, the lesion detection rate under FICE setting 1 was significantly higher than that by conventional CE (†).Back to article page
