2. Radiology - Wikipedia

   en.wikipedia.org/wiki/Radiology

   A radiologist interpreting magnetic resonance imaging. Dr. Macintyre's X-Ray Film (1896) Radiology ( / ˌreɪdɪˈɒlədʒi / rey-dee-ol-uh-jee) is the medical specialty that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography (which is why its name has a ...

3. Digital subtraction angiography - Wikipedia

   en.wikipedia.org/wiki/Digital_subtraction...

   MeSH. D015901. [ edit on Wikidata] Digital subtraction angiography ( DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast ...

4. Radiography - Wikipedia

   en.wikipedia.org/wiki/Radiography

   Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical ("diagnostic" radiography and "therapeutic") and industrial radiography. Similar techniques are used in airport security, (where "body scanners ...

5. X-ray - Wikipedia

   en.wikipedia.org/wiki/X-ray

   X-rays (or rarely, X-radiation) are a form of high-energy electromagnetic radiation. In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895 [1] and named it X-radiation to signify an unknown type of radiation.

6. Radiobiology - Wikipedia

   en.wikipedia.org/wiki/Radiobiology

   Radiobiology. Radiobiology (also known as radiation biology, and uncommonly as actinobiology) is a field of clinical and basic medical sciences that involves the study of the effects of ionizing radiation on living things, in particular health effects of radiation. Ionizing radiation is generally harmful and potentially lethal to living things ...

7. Digital radiography - Wikipedia

   en.wikipedia.org/wiki/Digital_radiography

   Digital radiography. Digital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette. [1] Advantages include time efficiency through bypassing chemical processing and the ability ...

8. Radiocontrast agent - Wikipedia

   en.wikipedia.org/wiki/Radiocontrast_agent

   Radiocontrast agents are substances used to enhance the visibility of internal structures in X-ray -based imaging techniques such as computed tomography ( contrast CT ), projectional radiography, and fluoroscopy. Radiocontrast agents are typically iodine, or more rarely barium sulfate. The contrast agents absorb external X-rays, resulting in ...

9. Radiological information system - Wikipedia

   en.wikipedia.org/wiki/Radiological_information...

   A radiological information system ( RIS) [1] is the core system for the electronic management of imaging departments. The major functions of the RIS can include patient scheduling, resource management, examination performance tracking, reporting, results distribution, and procedure billing. [2] RIS complements HIS (hospital information systems ...
