radiologisk

Radiological, or radiologisk in some languages, refers to the field of radiology, the medical specialty that uses imaging to visualize the inside of the body for diagnosis, monitoring, and treatment. Radiology covers both the production of images and their interpretation by radiologists. The main imaging modalities are X-ray radiography and fluoroscopy, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT). Interventional radiology applies imaging guidance to perform minimally invasive therapies, including angiography, biopsies, and drain placements.

Education and professionals: radiologists are physicians who interpret images, while radiographers or sonographers perform the scans. Radiology departments also involve medical physicists and technologists. Imaging safety is central, with protection against ionizing radiation, dose optimization under the ALARA principle, and careful use of contrast agents. MRI safety considerations are important for patients with implants, and iodinated or gadolinium-based contrasts carry risks that require screening and monitoring.

History and impact: since the discovery of X‑rays by Wilhelm Conrad Röntgen in 1895, radiology has evolved rapidly with CT in the 1970s–80s and MRI in the 1980s, expanding diagnostic capabilities. Professional bodies such as the ACR, ESR, and RSNA provide guidelines, accreditation, and standardized reporting systems (for example BI-RADS and PI-RADS). Radiology supports a wide range of clinical areas, from trauma and oncology to cardiology and neurology, and offers image-guided therapies that reduce invasiveness and recovery times.
