ONE-TO-ONE CORRESPONDENCE METHOD BETWEEN ENDOSCOPIC IMAGES AND HISTOLOGY

Abstract

Although many studies have attempted to correlate pathological images to endoscopic images, few cases have been examined by a systematic process for correspondence between endoscopic findings and histology. We previously reported a systematic process of achieving detailed adjustments of endoscopic findings to fit histopathological findings of the stomach, named the Kyoto One-To-One Correspondence Method (KOTO Method). Here we describe details of the correspondence method.

The method is composed of three steps: 1) photographing the whole ESD-resected specimen and magnified images of the resected specimen with a color digital camera and a stereomicroscope with a digital camera system for microscopy, respectively; 2) adjusting the histologic images to the whole and magnified surface images; and 3) adjusting the endoscopic image and histologic images.

One-to-one correspondence between endoscopic images and histologic images will improve endoscopic diagnosis.
