Profile

I am a diagnostic radiologist and nuclear medicine physician based in Tokyo, Japan.

After graduating from Kanazawa University in 2012, I completed my initial postgraduate clinical training at the Tokyo Metropolitan Geriatric Hospital and Institute of Gerontology. I subsequently undertook radiology residency training at the National Center of Neurology and Psychiatry, followed by a fellowship at the National Center for Global Health and Medicine. I earned my PhD from Tokyo Medical and Dental University, now the Institute of Science Tokyo, where I later joined the faculty. My doctoral research focused on the characteristic imaging findings of primary cerebellar lymphoma.

Throughout my career, I have witnessed and participated in several major advances in nuclear medicine in Japan, including the expansion of insurance coverage for DaTSCAN in 2014, the introduction of Lutathera therapy in 2021, amyloid PET in 2023, fluciclovine PET for glioma imaging in 2024, and PSMA PET and radioligand therapy in 2025. These experiences have strengthened my belief in the transformative potential of molecular imaging and theranostics to improve patient care.

I have also been involved in the clinical implementation of advanced imaging technologies, including digital semiconductor-detector PET systems, ultra-high-gradient MRI with MAGNETOM Cima.X, and photon-counting CT with NAEOTOM Alpha. My current interests center on translating technological innovation into meaningful clinical value. In particular, I aim to identify practical applications that improve diagnostic performance, workflow efficiency, and healthcare sustainability. I am especially interested in demonstrating how photon-counting CT can provide measurable clinical and operational benefits that support its adoption in routine clinical practice.

I believe that maximizing the value of advanced medical technologies requires more than hardware alone. Success depends on the effective integration of technology, software, skilled professionals, and multidisciplinary collaboration.

I also regard industry partners as important stakeholders in the shared effort to improve healthcare. By working together, clinicians, researchers, engineers, and industry professionals can translate technological capabilities into real-world clinical solutions that benefit patients and society.

My guiding principle is that people working in the same field are not competitors, but collaborators united by a common goal: advancing our discipline and improving patient care. I welcome opportunities to connect and collaborate with clinicians, researchers, technologists, industry partners, and innovators who share this vision.
