Department of Diagnostic Radiology


Current Director: Wang, Chien-Kuo (Aug. 2012 to present)


Former Directors: Tsai, Hong-Ming (Aug. 2000 – Jul. 2012)

Yu, Chin-Yin (Aug. 1989 Jul 2000)

Su, Cheng-Tau (Jun. 1988 – Aug. 1989)


The Department was initiated at the establishment of the Hospital in 1988.  There are currently 17 full-time attendant physicians, 6 part-time attendant physicians, 10 nurses, 49 medical radiological technologists, 13 ultrasound technologists, 1 mechanics and 13 clerks.


In addition to providing medical service of general radiologic examinations, special examinations, CT, MRI, and ultrasound examinations for outpatients and hospitalized patients at the Hospital, another main job is to train professional medical image physicians and education in general medical image for students.  Therefore, the Department has a comprehensive training program for resident physicians in the hope of ensuring each trained physician becomes an experienced and independent radiation expert after the exact training of four years and furthermore with the skill of passing on his or her experience to the coming generations.


Introduction to the attendant physicians and their specialties:

Dr.Tsai Hong-Ming—digestive radiology and interventional radiology, Dr. Cheng Li-Li—chest and breast imaging, Dr. Shun Hsing-Chiao—urological and reproductive radiology,Dr.Chung Ta-Jung—chest radiology, Dr. Hsien Chin-Chiang—bone/muscle radiology and general X-ray radiology, Dr. Kuo Tzong-Nan—abdomen and intervention radiation and Dr.Sun Ming-Hsiangneuroradiology and general X-ray radiology, Dr.Liu Yi-Sengaddomen and intervention radiation, Dr.Huang Chou-Ping— neuroradiology and general X-ray radiology, Dr.Wang Chien-Kuo —bone/ muscle radiology.


Equipment and examinations:

CT: the Department currently has equipped with 3 CT scanners.  One is a high-speed spiral CT and the other is multi-detector(or multi-slice) CT allowing 256 multi-slice canning.The speed of scanning is one row in half a second and the combination speed of 256 slices in one row reaches as high as 32 slices in a second.  The efficiency of examination is improved while the interruption of breath and movement is relatively reduced.  Also, contributing to upgrading of scanner and detectors, the resolution of image is significantly improved as well. Because of great progress in software, the diagnosis is no longer limited to cross-sectional images.  Imaging may be obtained with multi-plannar reconstruction including coronal and sagittal images and 3D volume data reconstraction with sheded surface display (SSD) or volume rendering(VR) techniques.  Furthermore, the 3D volume data can be widely applied to various processing techniques, such as CT angiography covering aorta to the extremity or aorta to the brain; virtual endoscopy including virtual colonoscopy, bronchoscopy or angioscopy; coronary artery angiography and myocardial perfusion study and ventricular function analy6sis.  Such involution of CT imaging provides alternative  choice other than conventional invasive procedures and reduce patient suffering during diagnostic procedures.


MRI scan: the Department currently has 3 MRI scanners.  They are mostly used in the diagnosis of neurological systems (brains and spines) and they perform better than CT.  They are also indispensable for muscles, ligaments and joints in sports medicine.  The advantages of MRI are higher contrast of soft tissue, being able to be formed into different sections (axial, coronal, and sagittal) and without radiation.


Ultrasound scanning: there are currently 10 ultrasound scanners.  8 are responsible for the examinations from outpatient services, emergency and hospitalized patients.  The other two smaller and movable ones are for special invasive examinations and education. The 11 machines for outpatient services, emergency and hospitalized patients have the function of Color Doppler with four having Power Doppler and high frequency Probes to allow for further blood stream mechanics research, diagn下午 03:40 2017/4/28osis of blood vessel diseases and the superficial tissues.


       X-Ray, or plain radiography: 7 digital X-ray machines are used to generate images of head and abdomen and are offered for ward and OPD patients . There is a traditional X-ray machine (with tomography function) for IVP study.  Two digital X-ray machines can provide fluoroscopy.  Fluoroscopy is used to take real-time images and is good for dynamic study of GI, urology, muscle skeleton systems or other invasive radiology.  There are two special X-ray machines for mammography.  Five portable X-ray machines can be brought to OR, ICU, ER, or wards for patients unable to move.


Interventional radiology procedures are an advance in medicine that replace open surgical procedures.  The department use in angiography (Siemens Axiom Artis FA), fluoro image (Toshiba and Siemens I-Conos R200), and ultrasound to guide small instruments such as catheters through the blood vessels or other pathways to treat disease percutaneously (through the skin).  These procedures are typically much less invasive and much less costly than traditional surgery.  Interventional radiology is applies in angiography, embolization, balloon angioplasty, percutaneous nephrostomy and double-J, biliary drainage and stenting, CT or sono-guide puncture, biopsy, aspiration, alcohol injection, cystic sclerosing therapy, abscess drainage, neurolytic block therapy, cementoplasy, gastrostomy etc.


In addition to clinical service, the department has always been responsible for education and training resident physicians to foster professionals in diagnostic radiology.  The Department also takes care of radiology imaging training for interns and fellow clinicians, continuous medical education program for general physicians and radiologists from other hospitals in Taiwan.   Weekly educational courses are also provided for the technicians.  In keeping with the current trends of digital imaging and archiving, the department established the Picture Archiving and Communication System (PACS).  The system for the entire hospital is to be completed in three years.  PACS was completed by the end of 2007.  Once PACS is built, the workforce can be downsized to allow better efficiency and reduce film waste.  PACS also provides better integration of medical resources for both clinical and educational purposes.
