Later in 1937, it was renamed as the Department of Radiology as the mother hospital also renamed to Empire University Hospital (Taipei). After the Second World War, the sovereignty of Taiwan returned to Republic of China, the name of the department was changed to Department of Physical Therapy and the mother hospital adopted its current name. In 1954, the Division of Radiation Therapy and Isotope room were integrated into the Department of Radiology in National Taiwan University Hospital. In 1990, the Department of Radiology was functionally divided into 3 divisions, namely Diagnostic Radiology, Nuclear Medicine and Therapeutic Radiology. As new imaging modalities such as ultrasonography and magnetic resonance imaging, which do not possess the property of radiation, added to the basic arsenals of X-ray machines, the Division of Diagnostic Radiology was renamed as Department of Medical Imaging in 1993. Functionally, there are 5 subspecialties in the Department of Medical Imaging including the neural, chest, body, musculoskeletal, and pediatrics groups and each has a chief who is responsible to the Chairman of the department. According to daily practice, the Department of Medical Imaging has 5 categories of work: plain film (those examinations not requiring special technique nor preparation, e.g. routine chest, abdomen, and skeleton x-rays, etc).; special examinations (those requiring special technique, contrast medium, as well as preparation, and are performed by radiologist, e.g. barium meal and enema studies, intravenous urograms, etc.); Computed Tomography (CT), a sophisticated X-ray whole body scanning technique capable of producing high resolution cross sectional images of the body; Magnetic Resonance Imaging (MRI), another sophisticated whole body scanning technique capable of producing high resolution sectional (not limited to axial) images of the body and does not require ionization radiation; Vascular and Interventional Radiology which deals with examinations of the vascular system of the body and a wide spectrum of therapeutic works that helps in treating patients, e.g. embolization therapy of cancer of the liver or aneurysm of the brain, dilatation of a narrowed artery or vein, drainage of obstructed bile ducts or urinary tract, biopsy of various body parts or drainage of abscesses, etc. Ultrasonography is a powerful tool that has been known as the doctors' second stethoscope. It does not produce ionization and is a very convenient tool to examine the solid organs of the body, e.g., the liver, kidneys, the female genital organs, thyroid glands, etc. Owing to its versatility, the machine can be brought into the Intensive Care Unit to facilitate bed-side examinations. In our hospital, the administration of this modality is under Integrated Departments, but radiologists do take part in the daily service as well as using this modality to guide us in certain therapeutic procedures, for example, biliary drainage in obstructive jaundice. In summary, nowadays the Department of Medical Imaging not only deals with diagnostic work, but also with tremendous applications in the treatment side, so that some in-operable cancers can be embolized, aneurysm in the brain or aorta that formerly should require open surgery can now be treated with coil embolization or stenting, so on and so forth, resulting in dramatically shortened hospital-stay (meaning less economical burden) and remarkably reduced discomfort of patients.本科部1911年以「理學治療科部」創立，當年臺灣仍處於日據時代。臺灣總督府醫院醫長桂三友，購置全台灣第一台X光機，即為X光科之前身。1937年，臺北帝國大學醫學部附設醫院成立，改稱為放射線科。台灣光復後則更名為理學治療科。1954年，除放射線診斷部門之外，增設放射治療及同位素室，並正式在臺大醫院中成立獨立科部。1990年配合全院組織架構改組，將放射線科分成獨立的放射線診斷、核子醫學和放射 線治療3個部門。1993年因應時代變遷， 將放射診斷科名稱正式改為影像醫學部。 本科目前在編制上依師資之專長分為放射線診斷、核子醫學和放射線治療。放射線診斷又 可區分為神經、胸部（包括乳房與呼吸循環系 統）、腹部（包括肝膽腸胃系統和泌尿道生殖系 統）、肌肉骨骼和小兒等次專科。各個部門均在 國內外學術研究上有相當的成就。 本科未來的發展：1.放射線診斷方面，除了在現有診斷專業和設備上持續精進之外，並投入 人力與物力積極發展「生物醫學影像(biomedical imaging)」之尖端技術。2.核子醫學方面，將持續改良傳統核醫造影技術，推動新式正子藥物研發，加強與臨床之接軌，期與世界級核醫水平並駕齊驅。 3.放射線治療方面，除了持續發展新式放射治療 方法，如螺旋刀、電腦刀、弧形刀、銳速刀等技術，並 投入放射基礎生物及高能放射物理之相關研究。 4.與國際著名影像科學中心交流，積極推動國際 性跨領域研究，並結合放射線診斷（尤其是磁振 造影和生物醫學影像）、核子醫學和放射線治療，針對國人特有或常見之疾病，如肝癌和鼻咽 癌等惡性腫瘤或糖尿病和心臟腦血管等疾病，發 展先進的診斷方式及各類微侵襲性治療法，以期在國際學術上居領先地位。
