Radiology diagnosticates and offers treatments by sophisticated high-resolution images such as plain radiography, special radiography using contrast media (dye), computed tomography (CT), and digital subtraction angiography. Also it conducts accurate high-resolution tests such as ultrasonography and magnetic resonance imaging (MRI). Through the development of computer technologies, there were developments of digital mammography, three-dimensional imaging, and functional magnetic resonance imaging. Gangnam Severance Hospital Radiology performs biopsy, abscess drainage, hemostasis for bleeding vessels, vascular malformation treatment, tumor embolization, angioplasty, and other non-surgical interventions.
