Department of Radiology
Organization and Clinical Activities
Department of Radiology was established in 1932. Radiology covers three major fields that are, Diagnostic Radiology (imaging and intervention), Radiation Oncology (radiotherapy) and Nuclear Medicine. The clinical, educational and research activities of Radiology are being carried out in cooperation with Department of Radiology in Research Institute of Medical Sciences, which has three (I associate professor and 2 associates) positions. Diagnostic Radiology covers about one half of the whole activities and Radiation Oncology and Nuclear Medicine one fourth each. Accordingly manpower is distributed approximately in that ratio. In addition, Department of Radiology mainly takes care of radiation protection and radiation safety in the hospital.
Clinical services on Diagnostic Radiology, Nuclear Medicine, and Radiation Oncology are provided in the centralized Clinical Radiology Service Department in cooperation with radiology technologists and nurses.
In the section of Diagnostic Radiology, there are eight plain X ray rooms, six CT rooms, three MRI rooms, five digital X-ray television rooms and four angiography rooms. All CT and MRI examinations are monitored and reported by diagnostic radiologists. Diagnostic radiologists, gastroenterologists and cadiologists mainly perform interventional procedures.
In the section of Nuclear Medicine, there are two SPECT rooms and two PET room, and one in vitro laboratory. These nuclear imaging procedures are chiefly performed and reported by radiologists and cardiologists.
Each year, over 700 new patients receive radiation therapy in the Radiation Oncology section. Highly accurate 3D radiation therapy is the most outstanding feature. Stereotactic radiation therapy for small lung or liver tumors was kicked off recently.
In the 9th floor of the new inpatient building, there are 18 beds in the Radiology ward, which are usually used for oncology patients receiving radiation therapy and chemotherapy. Some of them are sometimes used for patients receiving invasive diagnostic procedures such as interventional radiology (IVR), angiography and myelography. There are two special beds for radionuclide (RN) therapy in the same floor. In addition, four beds are allotted to terminal care ward located in the 14th floor.

Teaching Activities
Lectures are given to the fourth-, fifth- and sixth-year students to provide fundamental knowledge of diagnostic radiology, radiation oncology and nuclear medicine. Professor, associate professors and assistant professors as well as specialists assigned as part time lecturers take part in the education. A series of lectures about fundamentals of radiology and related sciences are given to the fourth-year students. As bed-side-learning (BSL) curriculum, eighteen small groups of the fifth-year students are taking part in mini-lectures and practice to learn basics of diagnostic radiology for one week. For the sixth-year students, another week of small group training and mini-lectures are prepared to learn advanced medical techniques of Radiation Oncology and Nuclear Medicine. They will learn detailed principles of image constructions in various kinds of imaging modalities and technology in radiation treatment against cancer. Postgraduate students are also welcome to each of subspecialties of radiology according to their interests.

Research Activities
Research activities in Radiology include clinical research, animal　experiments and development of instruments as well as computer-based new　technology.　 Diagnostic Radiology group in the department promotes research activities aiming at efficacy improvement of diagnostic imaging and expansion of its application. Multi-row detector helical computed tomography (MDCT) enables us to take tomographic images in three-dimensional (3D) fashion. Using the data acquired by MDCT various kinds of diseases in almost all parts of the body, from cerebral diseases to musculoskeletal diseases, can be displayed in 3D images. New 3D softwares developed in our departments are now widely used in the field of the gastrointestinal tract, lung, and central nervous system. In addition, we have opened a new laboratory section named image computing and analysis laboratory with invitation of a new staff from the Faculty of Engineering, the University of Tokyo. This section will contribute to development of novel softwares to abstract clinically useful information from the 3D imaging data more sophisticatedly. In the field of magnetic resonance (MR) imaging, MR digital subtraction angiography, perfusion imaging, and diffusion tensor imaging are the foci of research. These techniques are aggressively applied to the investigation of vascular and neoplastic diseases of the brain. Application of an open-type MR imaging unit to interventional radiology is another field of clinical research. In our section, MR imaging is specifically used to the treatment of vascular malformation. Basic animal experiments are also in progress in the field of functional MR imaging and diffusion and perfusion MR techniques.
Radiation oncology group promotes research projects in two major fields,　one is physical engineering aspect of radiotherapy and the other is　reduction of injuries due to radiation exposure. With the purpose of　achieving precise external irradiation, a new linear accelerator with C-arm　and multileaf collimator systems was developed and installed, which is　utilized mainly for non-coplanar radiation therapy in many patients　especially with brain tumor or head and neck tumor. Dynamic conical　conformal radiotherapy (Dyconic therapy) for metastatic brain tumors using　the accelerator is under evaluation. In addition to gamma knife　radiosurgery, this new accelerator based stereotactic radiosurgery for　brain diseases has been undergone, and stereotactic radiosurgery for body　tumors, such as lung tumor and liver tumor, has been investigated. A new　mobile linear accelerator to be used for intraoperative radiotherapy was　installed, which is the first equipment in Japan. A new technology to track mobile tumors, represented by lung tumors is under investigation in collaboration with accelerator makers. Novel approach to　terminal care of patients with various cancers has been investigated and　implemented in the new palliative care ward in cooperation with nurses.The relationship between terminal condition and cytokines, and newly　developed scoring system of quality of life are being evaluated. The　gustatory injury due to radiotherapy is investigated through animal　experiments in combination with the laboratory of biological function,　Graduate School of Agricultural and Life Sciences, University of Tokyo, and　through taste tests in clinical setting. Radiation injuries in many　tissues in the critically accident in Tokai-mura were also investigated.
　Nuclear Medicine group promote clinical research on images of function by the application of radioisotope-labeled tracer technology. In particular, emission tomography (PET and SPECT) is applied for the evaluation of cerebral blood flow and metabolism in patients with dementia, epilepsy, and cerebrovascular diseases. Cerebral blood flow, glucose metabolism and neural synaptic functions are measured for the understanding of normal and pathophysiological states of CNS disorders, using a variety of positron-emitter radiotracer, such as [O-15] H2O, CO2, O2, CO, [F-18] FDG, [C-11] methionine, [F-18]Dopa, [C-11]NMSP, NMPB and [C-11] raclopride. The study of dementia using SPECT and the standard brain atlas has made it possible to categorize the type of dementia. Evaluation of dopaminergic function by PET is very important in the differential diagnosis of parkinsonism. Cardiac PET and SPECT are also active fields. Myocardial viability, vascular reserve and sympathetic nerve denervation in the ischemic heart disease are evaluated with [F-18] FDG, [N-13] NH3, Tl-201 and [I-123] MIBG. Higher brain functions such as reading, speech and thinking have been studied with PET by comparing blood flow and receptor binding potential (BP) under various tasks and at rest. For the precise localization of activated brain function, computer processing and reconstruction of composite images of function and anatomy is an essential subject for investigation. In the near future, whole body FDG-PET would be one of the most promising studies for exploring metastatic lesions of cancer patients. Combination display of SPECT/PET with XCT/MRI would be a routine job and anatomo-functional images would play an important role in the clinical management of the patients.
