 Diagnostic radiology is one of the fundamental disciplines supporting modern medicine. 
 Our department provides comprehensive education for medical students, graduate students, and resident physicians, covering the principles and clinical applications of CT, MRI, PET, and nuclear medicine imaging, as well as image analysis and interpretation of digital radiography and other imaging modalities. We also place strong emphasis on education in image-guided minimally invasive therapy, known as interventional radiology (IVR). 
 During clinical clerkships, medical students use interactive digital educational materials developed by our department to learn cross-sectional anatomy and the interpretation of representative diseases. In addition, we have implemented a virtual reality (VR)-based educational system that enables students to acquire the fundamental techniques of IVR in a simulated environment. 
 For resident physicians, we provide structured training under the supervision of experienced faculty members. Through the preparation of diagnostic imaging reports, residents develop proficiency in image interpretation, differential diagnosis, and advanced imaging analysis. 
 For physicians pursuing board certification in diagnostic radiology, we offer advanced training in state-of-the-art imaging techniques and IVR procedures. The curriculum also emphasizes the planning of rational, minimally invasive imaging examinations and image-guided therapies, together with essential aspects of patient safety, including the appropriate use of medical radiation and the prevention and management of contrast media¨Crelated adverse reactions, such as allergic reactions and contrast-induced kidney injury.

 In the field of diagnostic imaging, we promote a wide range of clinical research using state-of-the-art imaging modalities such as CT, MRI, and PET-CT. From the perspective of imaging engineering, we are also actively engaged in the development of novel diagnostic imaging techniques, particularly for CT and MRI, as well as research on the biological effects of medical radiation exposure.
 In the field of interventional radiology (IVR), our major research themes include the development of new IVR therapies for hepatocellular carcinoma, IVR treatment for portal hypertension, and the establishment of non-vascular IVR procedures using IVR-CT systems.
 Our department conducts diverse research projects utilizing advanced technologies such as the latest CT, MRI, PET, and AI, and actively disseminates our findings both nationally and internationally. We also promote collaborative research with many companies, research institutes, and universities, including Canon Inc., Fujitsu Laboratories Ltd., Nemoto Kyorindo Co., Ltd., the Research Institute for Radiation Biology and Medicine, 91ÁÔÆæ, Kumamoto University, Kobe University, Institute of Science Tokyo, Okayama University, Radboud University in the Netherlands, and the University of Strasbourg in France.
