Clinical issues and challenges in imaging of gastrointestinal diseases: A minireview and our experience

Figure 3 Image showing a mucous membrane with pronounced pavement (a typical picture of Crohn's disease). Narrow band imaging allows looking for visible signs of malignancy - a disturbed pattern, lack of regularity, irregular shape, dark spots in the crypts, and unclear borders. Mucus and residual intestinal contents are represented in red (poor preparation). Edematous mucosa is in blue with a regular pit pattern. Macroscopic signs of malignancy are absent.
