Radiologien

Radiologien, the Danish and Norwegian term for radiology, is a medical specialty that uses imaging to diagnose and treat disease. Radiologists interpret imaging studies across a range of modalities and often perform image-guided procedures. Radiologic technologists operate equipment and support image acquisition under supervision.

Imaging modalities include radiography (X-ray), fluoroscopy, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine techniques such as single-photon emission computed tomography (SPECT) and positron emission tomography (PET). These tools enable structural and functional assessment of almost every organ system.

Interventional radiology is a major component of radiologien, involving minimally invasive, image-guided procedures such as biopsies, drainages, vascular interventions, and tumor ablations. These procedures are performed by radiologists and are often done in specialized suites, sometimes on an outpatient basis.

Safety and training emphasize radiation protection and dose optimization, patient shielding, and equipment quality assurance. Training typically requires a medical degree followed by a radiology residency and board certification, with subspecialties in neuroradiology, pediatric radiology, musculoskeletal radiology, chest radiology, and interventional radiology.

History: The field originated with the discovery of X-rays in 1895 and expanded to include CT in the 1970s and MRI in the 1980s. The digital era introduced PACS, rapid image sharing, and advanced image processing, expanding the role of radiologien in diagnosis, treatment planning, and interventional care.
