“…This suggests that enhancing the color tone improves the visibility of pharyngeal and esophageal cancers, rather than emphasizing the structure. TXI mode2 did not contain an algorithm to emphasize the color tone, and the ∆E value was improved by the value of ∆L (Table 2, Figure 4) [13]. The lower ∆E value in TXI mode2 was sufficient, but the visibility score was lower than that of TXI mode1.…”

Texture and color enhancement imaging (TXI) has been developed as an image-enhanced endoscopy technology. TXI mode2 enhances texture and brightness, and TXI mode1 also enhances color. This study aims to assess the color differences in squamous cell carcinoma (SCC) suspicious lesions in the pharynx and esophagus using white light imaging (WLI), TXI mode1, TXI mode2, and narrow-band imaging (NBI). A total of 59 SCC suspicious lesions from 30 patients were analyzed. The color differences (ΔE) between the lesion and the surrounding mucosa were calculated for each modality. The color value was assessed using the Commission Internationale d’Eclairage L*a*b* color space. The visibility of the lesion in each modality was evaluated and compared to that in the WLI by six endoscopists. The mean ΔE values in the WLI, TXI mode1, TXI mode2, and NBI were 11.6; 18.6; 14.3; and 17.2, respectively, and the ΔE values of TXI mode1, TXI mode2, and NBI were significantly higher than those of the WLI (p < 0.001). No lesions had worse visibility, and 62.5% (37/59) had improved visibility, as assessed by more than half of the endoscopists in TXI mode1. TXI mode1 can enhance color changes and improve the visibility of SCC suspicious lesions in the pharynx and esophagus, compared to WLI.

“…There are several reports on the quantitative analysis of TXI. Sato et al performed a quantitative analysis using endoscopic images of the gastrointestinal tract from an in vivo porcine study [ 26 ]. Their quantitative analysis included edge-based contrast measurements, the standard deviation of the averaged illumination, and the color difference.…”

Background and aim: Olympus Corporation released the texture and color enhancement imaging (TXI) technology as a novel image-enhancing endoscopic technique. We investigated the effectiveness of TXI in the imaging of serrated colorectal polyps, including sessile serrated lesions (SSLs). Methods: Serrated colorectal polyps were observed using white light imaging (WLI), TXI, narrow-band imaging (NBI), and chromoendoscopy with and without magnification. Serrated polyps were histologically confirmed. TXI was compared with WLI, NBI, and chromoendoscopy for the visibility of the lesions without magnification and for that of the vessel and surface patterns with magnification. Three expert endoscopists evaluated the visibility scores, which were classified from 1 to 4. Results: Twenty-nine consecutive serrated polyps were evaluated. In the visibility score without magnification, TXI was significantly superior to WLI but inferior to chromoendoscopy in the imaging of serrated polyps and the sub-analysis of SSLs. In the visibility score for vessel patterns with magnification, TXI was significantly superior to WLI and chromoendoscopy in the imaging of serrated polyps and the sub-analysis of SSLs. In the visibility score for surface patterns with magnification, TXI was significantly superior to WLI but inferior to NBI in serrated polyps and in the sub-analysis of SSLs and hyperplastic polyps. Conclusions: TXI provided higher visibility than did WLI for serrated, colorectal polyps, including SSLs.

“…Texture and color enhancement imaging (TXI) is designed to enhance three image factors in WLI (texture, brightness, and color) to define subtle tissue differences clearly. TXI has two settings, mode1 with color enhancement and mode2 without color enhancement [ 18 ]. Dobashi et al examined the color difference between the lesion and surrounding mucosa by WLI, TXI mode1, TXI mode2, and NBI in 59 SCC lesions of the pharynx and esophagus.…”
