Professor Daiju Ueda Featured in an Interview Article in The Yomiuri Shimbun

An interview with Professor Daiju Ueda of the Graduate School of Medicine, Osaka Metropolitan University, was published in The Yomiuri Shimbun (morning edition, Kansai section / Yomiuri Shimbun Online) on September 9, 2026. 

The article is headlined (in Japanese): "Interview with Professor Daiju Ueda of Osaka Metropolitan University: Medical AI reaches 90% diagnostic accuracy for breast cancer, seemingly catching up with veteran physicians — yet 'bias' in training data may lead to misdiagnosis."

Topics covered in the article include:

  • Motivation to begin developing medical AI
  • The development of a deep-learning-based breast cancer diagnostic support system and episodes concerning its diagnostic accuracy
  • The current use of AI that detects cerebral aneurysms from MRI images and AI that identifies lung cancer from chest X-rays at many medical institutions
  • How "bias" in training data can affect diagnostic accuracy, and his advocacy for richer information in AI package inserts (instruction documents)
  • The domestic situation surrounding Software as a Medical Device (SaMD)

The article features Professor Ueda's comments addressing both the promise and the challenges of medical AI, such as: "AI has the ability to instantly examine every corner of a single image and detect diseases that human physicians may overlook," and "By making the most of AI's characteristics, we may be able to help solve problems in regional areas where physicians and diagnostic equipment are in short supply."
