What 広島大学病院 does

Hiroshima University Hospital's Department of Diagnostic Radiology is a public-sector academic clinical and research unit within Hiroshima University Hospital, a national university corporation under Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT). Originally established in 1948 as a unified radiology department, it was split in 2009 into separate diagnostic radiology and radiation oncology laboratories, with the diagnostic radiology department relaunched under Professor Kazuo Awai in February 2010 and currently led by Professor Yuko Nakamura.

The department provides diagnostic imaging interpretation services (CT, MRI, PET-CT) to all clinical departments within Hiroshima University Hospital and performs interventional radiology (IVR) procedures including tumor ablation, embolization, angioplasty, and biopsy. It operates advanced imaging equipment including a 320-detector CT scanner with 150-micron spatial resolution, 3-Tesla MRI systems (Philips Ingenia 3T, Toshiba Titan 3T), PET-CT, photon-counting detector CT, and an Artis ZEE Biplane hybrid angiography system. Research is centered on deep learning reconstruction (DLR/AiCE) co-developed with Canon Medical Systems, ultra-high-resolution CT, AI-based image retrieval for diffuse lung diseases with Fujitsu Research, and the biological effects of low-dose X-ray exposure.

The department serves as a regional referral and training center for the Chugoku region of Japan, supporting approximately 20 affiliated training hospitals, and publishes over 20 English-language papers annually with 15-20 RSNA presentations per year. Revenue comes from government appropriations, medical service fees billed under Japan's national health insurance system, and research grants from Japanese government agencies and medical device companies. The department holds two industry-academia joint research chairs and collaborates internationally with Radboud University Nijmegen and Illinois Institute of Technology.
