Diagnostic Imaging and Nuclear Medicine

kao Kaori Togashi, M.D., Ph.D. Professor btn

Department of Diagnostic Imaging and Nuclear Medicine has committed to teaching diagnostic radiology and nuclear medicine, and providing medical services for patients with a variety of disorders using various imaging modalities, such as CT, MRI, Ultrasound and Positron Emission Tomography. Interventional Radiology is also conducted for minimally-invasive therapy as well as diagnosis. Imaging plays an indispensable role in current medical practice, and our department is leading it by bringing imaging excellence not only into various departments in our institute, but also into the community with latest achievements of biomedical imaging.

Research and Education

Our research interests are (i) physical and mathematical investigations for development of the effective use of imaging modalities, (ii) establishment of new imaging methods and technologies for diagnosis and image-assisted minimally-invasive therapy, and (iii) basic medical researches using biomedical and pathological methods related to imaging. Our researches cover varieties of fields and modalities, and we collaborate with various departments of basic sciences, engineering and medical information. Although our main focus is on clinical problems, we also conduct experimental studies, such as molecular imaging that helps to understand hypoxia and other cancer-related conditions and development of a novel contrast material.
In education, we serve not only for residents who will be a radiologist, but for those who will not. An optional course for two months is provided to intensively learn diagnostic imaging, which is required in all medical fields. We also provide four-year programs to be a professional radiologist, who will practice in at least two institutions to learn variety of diagnostic examinations covering the whole body.
