Dror Zur, Founder and CEO of MAGENTIQ EYE, discusses the opportunities for reducing the risk of colorectal cancer through AI-assisted colonoscopies. He points out the relatively high polyp miss rate that can be due to the size of the polyp, interpretations by physicians, and limitations of the procedure room. The MAGENTIQ-Colo AI system analyzes colonoscopy videos in real time and alerts the physician to polyps with a bounding box.
Dror explains, "The procedure room is not a perfect place. There is some noise, and there are other people sometimes. There can be interference. Also, sometimes, the polyp passes through the video very fast, and even if it is not a very small polyp, it's hard to detect it. Sometimes, the point-of-view is such that it is hard to see. Sometimes, it is hidden behind a fold or something like that, and then only a very small part of it can be seen. It is hard to detect the polyp this way. There are several reasons for that."
"The system takes the video, breaks it into frames, and analyzes each frame by the AI engine of the system, detects polyps if they are there, and shows the bounding box on the video where the physician is looking. It actually doesn't change anything in the clinical workflow. The procedure stays exactly the same. You just have additional information, which is decision support information for the physician that helps them to decide if there is a polyp. It is just plug-and-play. The installation is very simple."
"This is, by the way, done by doing two colonoscopy tests, one immediately after the other with the same patient, and what is being detected in the second one is the miss rate of the first one, polyps that were not detected in the first one. It's called adenoma miss rate, the percentage of missed adenomas. The study showed a relative increase of 37% in the adenoma per colonoscopy, the average number of adenomas that are detected, and the miss rate is cut almost by half."
