Researchers in Japan used artificial intelligence to spot early-stage stomach cancer on endoscopic images with high accuracy. Researchers at Riken and the National Cancer Center in Japan have successfully used artificial intelligence (AI) to spot early-stage stomach cancer on endoscopic images with high accuracy. The researchers collected 100 endoscopic images of early-stage stomach cancer and 100 images of normal stomach tissue to test the deep-learning AI. The team says the AI was able to determine whether an endoscopic image showed early-stage cancer or normal stomach tissue in 0.004 seconds. In addition, the algorithm correctly identified cancer in 80% of cancer images, and confirmed normal tissues with 95% accuracy.

Two Japanese national research institutes have succeeded in using artificial intelligence to identify early stage stomach cancer with a high accuracy rate. The breakthrough may help extend the lives of patients in Japan, where stomach cancer is one of the leading causes of death. According to the National Cancer Center, 45,531 people died of stomach cancer in 2016. According to Riken and the National Cancer Center, it took AI only 0.004 seconds to judge whether an endoscopic image showed early stage cancer or normal stomach tissue. AI correctly detected cancer in 80 percent of cancer images, while the accuracy rate was 95 percent for normal tissue.

Two Japanese national research institutes said Saturday they have succeeded in using artificial intelligence to identify early-stage stomach cancer with a high accuracy rate. The breakthrough may help extend the lives of more cancer patients in Japan, where stomach cancer is one of the leading causes of death. According to Riken and the National Cancer Center, it took AI only 0.004 seconds to judge whether an endoscopic image showed early-stage cancer or normal stomach tissue. AI correctly detected cancer in 80 percent of cancer images, while the accuracy rate was 95 percent for normal tissue. The accuracy rates were as high as those of veteran doctors, the institutes said, adding that they will aim to put AI into practical use as a device to support doctors in making diagnoses.
