Radiography section provides imaging services by exposing a part of the body to a small dose of ionizing radiation to produce internal images of the body. The types of procedures include conventional diagnostic X-ray for the thorax, abdomen, bone, etc, mammography and bone density scan.

X-ray computed tomography (CT) is a method of body imaging in which a thin X-ray beam rotates around the patient. CT scans provide cross-sectional images to a few millimeters thickness, therefore, it is possible to detect even tiny lesions in the body. CT is now very widely used for the diagnosis and assessment of treatment.
As CT uses X-rays, at our department, we use an automatic exposure control system (AEC), which can reduce the radiation exposure during the CT examination.

Magnetic resonance imaging (MRI) is a noninvasive imaging examination that uses a strong magnetic field, instead of X-ray. It can provide images of any cross-section of organs and tissues with excellent tissue contrast. It can demonstrate detailed anatomy and pathology of soft tissue and nerves, and visualize the blood vessels without administration of contrast agent.

Interventional radiology (IVR) techniques that use angiography techniques have enabled minimally invasive endovascular procedures without performing surgery.

Nuclear medicine uses a small amount of radioactive tracer to visualize morphology and functions of various organs. As nuclear medicine scans are very accurate for diagnosing functional abnormality, they have been widely applied for the evaluation of heart and brain disorders. Positron emission tomography (PET) scans are now essential for the diagnosis of some malignancies.

Radiotherapy is one form of local treatment for cancer and plays the same role as surgery and, with radiotherapy we have greater chance of organ preservation while maintaining its function. A better quality of life (QOL) can be expected after radiation therapy and its is now one of the major therapeutic options for cancers, along with surgery and chemotherapy.
