Diagnosis of Early Gastric Cancer by Magnifying Endoscopy with NBI from Viewpoint of Histological Imaging: Mucosal Patterning in terms of White Zone Visibility and Its Relationship to Histology

<table>The mechanism responsible for white zone visibility at an angle. A-NBI light enters the mucosa from the intervening part in the direction of the crypt epithelium. It is then scattered, and the white zone appears as shown in Figure <a href="../fig3/">3</a>(b)A. B-NBI light entering crypts passes through the epithelium and is absorbed by the hemoglobin of red blood cells in blood vessels. As a result, the blood vessels appear as brown lines as shown in Figure <a href="../fig3/">3</a>(b)B. </table>
