Abstract

The present invention provides a diagnostic support method and a diagnostic support system with which it is possible to accurately identify various small intestinal diseases using a convolutional neural network (CNN) system based on small intestine endoscopic images or moving images from a wireless capsule endoscope (WCE). A diagnostic support system according to an aspect of the present invention uses first endoscopic images of small intestines from a WCE and definitive diagnostic results of diseases respectively corresponding to the first endoscopic images to train a CNN system. The trained CNN system detects a small intestinal disease on the basis of a second endoscopic image of a small intestine from a WCE, and outputs at least one of a probability score and a region corresponding to the disease positivity. Said diagnostic support system is characterized in that the first endoscopic images are WCE endoscopic static images of small intestines, and the second endoscopic image is a WCE endoscopic moving image of a small intestine.
