Diagnosis of extent of early gastric cancer using flexible spectral imaging color enhancement

Figure 6 The irregular microvascular pattern of lesions is clearly visualized with half magnification. A: Conventional image (EG590-ZW) in a close-up view reveals a nearly flat lesion with a slightly reddish portion in the anterior wall of middle body; B: Flexible spectral imaging color enhancement (FICE) image enhances a reddish lesion leading to a clear demarcation line; C: Conventional image with half magnification shows an enriched microvascular structure on the tumor surface; D: FICE image with half magnification allows a clear visualization of irregular microvascular and microstructural pattern suggesting gastric cancer with the possible histological type of well-differentiated adenocarcinoma.
