Radiation was first discovered by Wilhelm Röntgen around 1880. Through continued scientific and medical advances, radiation continues to play a central role in the field of medical examination and treatment in today’s modern medicine. Radiology is largely divided into diagnostic and therapeutic areas. With the rapid development of digital imaging technology and the imaging equipment such as CT, MRI, ultrasound, DSA, as well as mere scanning device using X-rays, it has now become possible to obtain the test results and diagnoses more accurately and quickly. In addition, through the advancement of the field of interventional radiology, radiation greatly contributes to the treating of various vascular disorders and performing of drainage without risks of surgery or anesthesia. In 2003, the formally established name of Department of Diagnostic Radiology has been changed to Department of Radiology. Currently, Department of Radiology has 20 professors and 12 residents who are experts in the fields of chest, abdomen, genitourinary, neurointervention, breast, thyroid, musculoskeletal system, and intervention, performing diagnoses and treatments using the medical imaging technology.
