SUMMARY
Naoki Takahashi, M.D., is a radiologist whose research focuses on artificial intelligence (AI) applications in prostate MRI and advanced abdominal imaging. His current work centers on AI tools developed by his team to support prostate MRI interpretation, including prostate segmentation and prostate cancer detection. Dr. Takahashi studies how these tools can be translated into clinical practice and how their performance, workflow impact and clinical value should be monitored during and after implementation. His research aims to evaluate AI-assisted prostate MRI in real-world care settings and ensure that these tools improve care in a safe, reliable and clinically meaningful way.
Dr. Takahashi also has a long-standing research focus in advanced abdominal imaging, especially IgG4-related disease and autoimmune pancreatitis.
Focus areas
- Development of AI tools for prostate MRI. Dr. Takahashi and his team have developed AI tools to address critical challenges in prostate MRI interpretation, including prostate segmentation and detection of clinically significant prostate cancer. Their work uses large collections of clinical prostate MRI examinations to train and test models that can identify key imaging features, reduce manual effort and improve consistency in image analysis. These efforts aim to create clinically relevant AI tools that support radiologists in delivering more accurate and efficient prostate cancer evaluation.
- Clinical translation and real-world assessment of prostate MRI AI. Dr. Takahashi studies how prostate MRI AI tools perform as they move from model development toward clinical use. With support from the Gerstner Scholars Program in AI Translation, his work is evaluating AI-assisted prostate cancer detection in real-world practice, including model performance, workflow integration, radiologist interaction with AI outputs and potential impact on patient care. This research emphasizes careful monitoring after deployment to ensure that AI tools remain safe, accurate and useful in clinical practice.
- Advanced abdominal imaging and IgG4-related disease. Dr. Takahashi's broader research includes advanced CT and MRI techniques for abdominal diseases, with a particular focus on IgG4-related disease and autoimmune pancreatitis. He has contributed to diagnostic approaches that help distinguish autoimmune pancreatitis from pancreatic cancer and other conditions with similar imaging appearances, including the development of the HISORt criteria for autoimmune pancreatitis. This work supports more accurate diagnosis, appropriate treatment selection and avoidance of unnecessary procedures.
Significance to patient care
Dr. Takahashi's research focuses on making medical imaging easier to use and more helpful for patients, especially for prostate and abdominal conditions.
For prostate cancer, he is studying how AI can support radiologists in reading MRI scans. These tools can help outline the prostate, spot areas that may look abnormal and make scan results more consistent. By carefully developing and testing these tools, Dr. Takahashi aims to ensure that AI helps provide accurate, reliable information for patients and their care teams.
He also studies advanced imaging techniques for the abdomen, which can help diagnose complex conditions such as IgG4-related disease and autoimmune pancreatitis. These conditions can sometimes look like cancer on imaging, but they require different treatment. Improving how these conditions are identified can help people avoid unnecessary procedures and get the right treatment sooner.
