Radiologist
the organs of the reproductive and urinary tracts.
Radiologist – Head and Neck. The subspecialty concerned with the diagnostic radiology of diseases of the head and neck.
Radiologist – Interventional. The subspecialty that uses fluoroscopy, CT, and ultrasound to guide passage through the skin by needle puncture, including introduction of wires and catheters for performing procedures such as biopsies, draining fluids, inserting catheters, or dilating or stenting narrowed ducts or vessels.
Radiologist – Magnetic Resonance Imaging (MRI). The subspecialty relating to magnetic resonance imaging (MRI), a diagnostic radiological modality using nuclear magnetic resonance technology. MRI uses radio waves and a strong magnetic field rather than x-rays to provide clear and detailed pictures of internal organs and tissues.
Radiologist – Musculoskeletal. The subspecialty concerned with the diagnostic radiology of diseases of the muscles and the skeleton.
Radiologist – Neuroradiology. The subspecialty concerned with the diagnostic radiology of diseases of the central nervous system, head, and neck.
Radiologist – Nuclear Medicine. The subspecialty concerned with the diagnostic and therapeutic uses of radionuclides, excluding the therapeutic use of sealed radiation sources.
Radiologist – Pediatric Radiology. The subspecialty concerned with children’s radiology and the radiological manifestations of diseases of children.
Radiological Physicist. The subspecialty relating to the therapeutic, diagnostic and safe use of applications of x-rays, gamma rays, electron and charged particle beams, neutrons and radiations from sealed radionuclide sources; relating to the equipment associated with their production, use, measurement and evaluation and instrumentation required to perform appropriate radiation surveys; relating to the quality of images resulting from their production and use; and relating to medical health physics.
Radiologist – Radiobiology. The branch of radiology or pathology concerned with the effects of radiation on cells and tissues.
Radiologist – Ultrasound. The subspecialty concerned with the use of ultrasound (high frequency sound waves) and other techniques for medical diagnosis.
Radiation Oncologist – Radiation Oncology. The medical specialty of radiation oncology, the use of radiation for the therapy of neoplasms (tumors).

- Radiology
The medical specialty concerned with radiation for the diagnosis and treatment of disease, including both ionizing radiation such as X-rays and nonionizing radiation such as ultrasound. Also known as roentgenology.
- Radiology, interventional
The use of image guidance methods to gain access to the deepest interior of most organs and organ systems. Interventional radiology includes the use of balloons, catheters, microcatheters, stents, therapeutic embolization (deliberately clogging up a blood vessel), and more. The specialty of interventional radiology overlaps with other surgical arenas, including interventional cardiology, vascular surgery, endoscopy, […]
- Radiolucent
Permeable to one or another form of radiation, such as X-rays. Radiolucent objects do not block radiation but let it pass. Plastic is usually radiolucent. The opposite of radiolucent is radiopaque.
- Radiomimetic
Imitating radiation. A radiomimetic drug is one that imitates the effects of radiation as in the case of chemicals such as nitrogen mustards which are used in cancer chemotherapy. The “mimetic” part of “radiomimetic” comes from the Greek verb “mimeisthai” meaning “to imitate” and from “mimos” meaning “mime.” (The English word “mime” also comes from […]
- Radionuclide
An unstable form of a chemical element that radioactively decays, resulting in the emission of nuclear radiation. Also called a radioisotope.
