Radiology
The Department of Radiology comprises the divisions of Diagnostic Radiology (X-ray, CT, MRI, angiography), Nuclear Medicine (scintigram, PET), and Radiation Oncology (Linac, Tomotherapy, gamma knife, RALS).
Medical services
The Diagnostic Radiology Division performs various imaging examinations (X-ray, CT, MRI, and angiography) for assessment and diagnosis in malignant and inflammatory diseases, and provides treatment choice for tumors and vascular lesions using interventional radiology (image-guided less invasive diagnosis and therapy). The Division of Nuclear Medicine performs radioisotope scintigraphy for assessment and diagnosis, as well as SPECT/ PET examinations. The Division of Radiation Oncology provides treatment for cancer using radiation.
Diagnosis and treatment policy
The advantages of radiotherapy include less physical burden on patients and possible preservation of the structure and function of the affected organ. Complete cure can be achieved by radiotherapy alone or in combination with anticancer agents depending on the type and stage of the disease.
Specialties
Image processing using multislice CT/ MRI
An image processing and statistical analysis laboratory has been established for clinical application and basic research in line with computer-aided detection and artificial intelligence.
PET
Detection of malignancies and assessment of malignancy grade and stage, assessment of central nervous system diseases, quantitative measurement of cerebral blood flow have been established.
Target diseases
Any disease involving structural and functional abnormality that can be visualized radiographically (Diagnostic Radiology and Nuclear Medicine Divisions) and any disease with radioactive sensitivity (Radiation Oncology Division)
Advanced treatments/ Specialized treatments
Stereotactic radiation to the head
A technique to deliver radiation to a lesion with an accuracy of within 1 mm using three Linac and gamma knife to treat metastatic brain tumors, cerebral arteriovenous malformation, benign brain tumors (acoustic schwannoma, meningioma, etc.)
Stereotactic radiation to the trunk
A technique to deliver radiation to a thoracoabdominal lesion with an accuracy of within 5 mm designed mainly to treat lung tumors (primary or metastatic) and liver tumors (primary or metastatic) and prostate cancers.
Intensity modulated radiotherapy (IMRT)
A technique to deliver beams of radiation of variable intensity to tumors in the head and neck
