Volume 4, Issue 1, Pages 7-10 (January 2019) Simultaneous detection and characterization of diminutive polyps with the use of artificial intelligence during colonoscopy Yuichi Mori, MD, PhD, Shin-ei Kudo, MD, PhD, Masashi Misawa, MD, PhD, Kensaku Mori, PhD VideoGIE Volume 4, Issue 1, Pages 7-10 (January 2019) DOI: 10.1016/j.vgie.2018.10.006 Copyright © 2018 American Society for Gastrointestinal Endoscopy Terms and Conditions

Figure 3 The tip of the endocytoscope. It has the function of a contact microscopy system with 520-fold magnification power, and it also works as an ordinary high-definition colonoscope.

Figure 4 The artificial intelligence system indicates the automatic detection of a flat adenoma (3 mm, 0-IIa) in the ascending colon by outputting a yellow color in the 4 corners of the display screen and emitting a warning sound. The probability of the presence of the polyp is displayed in the upper-left corner of the endoscopic image.

Figure 5 The artificial intelligence system automatically outputs the predicted pathologic features of the detected polyp as neoplastic with a probability of 90% immediately after the endoscopist pushes the capture button of the endocytoscope. The polyp shown in this figure is the same one described in Figure 4.

Figure 6 The artificial intelligence system indicates the automatic detection of a flat hyperplastic polyp (3 mm, 0-IIa) in the rectum by outputting a yellow color in the 4 corners of the display screen and emitting a warning sound.

Figure 7 The artificial intelligence system automatically outputs the predicted pathologic features of the detected polyp as non-neoplastic with a probability of 89% immediately after the endoscopist pushes the capture button of the endocytoscope. The polyp shown in this figure is the same one described in Figure 6.
