1) data on file Data on file with Olympus (DC00489968)
Scope: GIF-EZ1500
Case: Early gastric cancer
Organ: Stomach
Patient information: F, 76
Medical history: History of chronic dyspepsia and recent onset pain abdomen and weight loss
1. WLI
Single nodular lesion seen at antrum with elevated edges and indistinct margins. The demarcation line is not clearly visible in WLI.
2. TXI™ Technology
Upon TXI™ Technology assessment, the border of the lesion is clearly seen with irregular shape and color, suspicious of neoplastic etiology. The demarcation line is clearly visible.
3. NBI™ Technology
NBI™ Technology with electronic zoom demonstrated clear demarcation line (DL), near the lesion, with irregular micro surface (MS) and microvascular pattern (MV) s/o Early gastric cancer. Light blue crest (LBC) sign on epithelial surface is s/o Intestinal Metaplasia.
4. WLI
Single nodular lesion seen at antrum with elevated edges and indistinct margins. The demarcation line is not clearly visible in WLI.
5. TXI™ Technology
Upon TXI™ Technology assessment, the border of the lesion is clearly seen with irregular shape and color, suspicious of neoplastic etiology. The demarcation line is clearly visible
6. NBI™ Technology
NBI™ Technology with electronic zoom demonstrated clear demarcation line (DL), near the lesion, with irregular micro surface (MS) and microvascular pattern (MV) s/o Early gastric cancer. Light blue crest (LBC) sign on epithelial surface is s/o Intestinal Metaplasia.
7. TXI™ Technology mode 1
Upon TXI™ Technology assessment, the border of the lesion is clearly seen with irregular shape and color, suspicious of neoplastic etiology. The demarcation line is clearly visible.
8. TXI™ Technology Mode 2
TXI™ Technology mode 2 shows enhancement of brightness and texture compared to WLI.
Overall Comment
TXI™ Technology can enhance brightness selectively in dark areas of endoscopic images and can enhance subtle tissue differences1 such as slight morphological and/or color changes over conventional enhancement methods including structure enhancement and color enhancement. Comparing TXI™ Technology with conventional white light imaging (WLI) for real-world image processing, TXI™ Technology can achieve image enhancement with characteristics of WLI appearance while preventing over-enhancement observed in other methods. TXI™ Technology has two modes, mode1 and mode 2. Enhancement of brightness and texture is similar in both modes. The color contrast is enhanced with TXI mode 1 whereas TXI mode 2 has a more natural color tone as no color enhancement is performed. Overall, TXI™ Technology provides a balance of improving image features important for the physician searching for abnormalities (selective increase in brightness, color separation, and texture enhancement) while minimizing gross changes that may negatively impact familiarity (naturalness).1
