Radiology

Radiology

The Department of Radiology comprises the divisions of diagnostic radiology (CT, MRI, angiography), nuclear medicine (scintigram, PET), and radiotherapy (Linac, gamma knife).

Medical services

The Diagnostic Radiology Division performs various imaging examinations (CT, MRI, angiography) for assessment and diagnosis, and provides treatment for tumors and vascular lesions using interventional radiology (IVR). The Division of Nuclear Medicine performs radioisotope (RI) scintigraphy for assessment and diagnosis, as well as SPECT/ PET examinations. The Division of Radiotherapy 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 for this technique

PET

Detection of malignancies and assessment of malignancy grade and stage, assessment of central nervous system diseases, quantitative measurement of cerebral blood flow

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 (Radiotherapy 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 C-arm-mounted 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)

Intensity modulated radiotherapy (IMRT)

A technique to deliver beams of radiation of variable intensity to tumors in the head and neck

Sealed source radiotherapy for prostate cancer (brachytherapy)

Permanent implant of very small capsules containing radioactive iodine for early-stage prostate cancer
