Radiology

Our medical team at the Department of Radiology in Seoul National University Hospital is composed of radiology specialists, radiology technicians, nurses, and administrative personnel and provides optimal medical care through diagnosis, treatment, imaging information management, and patient-centered care based on extensive experience using various imaging techniques.

1. Our Roles 
- Development and implementation of various imaging techniques and diagnosis of diseases through imaging examinations
- Advice on medical treatment through imaging-guided biopsy, non-surgical treatment, and collaboration with other departments
- Follow-up and medical advice for patients who received imaging-guided non-surgical treatment

2. Clinical Services
The Department of Radiology at Seoul National University Hospital employs 71professors, 15 clinical fellows, and 29 residents, a total of 115 employees (as of 2022). Annually, we perform approximately 230,000 computed tomography, 150,000 ultrasound and ultrasound-guided procedures, 88,000 magnetic resonance imaging, and 35,000 angiographies (as of 2020). We have a collaborative system with other departments by managing the Cancer Imaging Center at the cancer hospital and the Department of Pediatric Radiology at the children's hospital.

3. Equipment and Facilities
The Department of Radiology at Seoul National University Hospital is equipped with 11 computerized tomography (CT) scanners including dual-energy CT, which are special state-of-the-art devices, 11 magnetic resonance imaging systems (MRI) centering on the latest high-specification 3T, and 27 ultrasound devices including the high-specification models that can perform real-time image fusion with CT/MRI. We also employ a PET-MRI system that simultaneously provides both MRI and PET data, jointly with the Department of Nuclear Medicine. In addition, we strive for the development and clinical use of state-of-art imaging technologies such as functional MRI, MR spectroscopy, and molecular imaging and provide the best diagnosis and treatment to patients with cutting-edge devices and highly trained professionals.

4. Subspecialties
The Department of Radiology at Seoul National University Hospital has 11 divisions. The medical professionals in each division are playing a leading role in the field of radiology inside and outside of the country through the diagnosis and treatment, active research (2,758 published papers, 45,311 citations, and 16.4 citations per paper in 2011 - 2020), and education programs.
