  2. 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 ...

  3. Positron emission tomography - Wikipedia

    en.wikipedia.org/wiki/Positron_emission_tomography

    Positron emission tomography ( PET) [ 1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption. Different tracers are used for various imaging ...

  4. Projectional radiography - Wikipedia

    en.wikipedia.org/wiki/Projectional_radiography

    Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation. The image acquisition is generally performed by radiographers, and the images are often examined by radiologists. Both the procedure and any resultant images are often simply ...

  5. CT scan - Wikipedia

    en.wikipedia.org/wiki/CT_scan

    CT scan. A computed tomography scan(CT scan; formerly called computed axial tomography scanor CAT scan) is a medical imagingtechnique used to obtain detailed internal images of the body.[2] The personnel that perform CT scans are called radiographersor radiology technologists.

  6. Fluoroscopy - Wikipedia

    en.wikipedia.org/wiki/Fluoroscopy

    Fluoroscopy ( / flʊəˈrɒskəpi /) [ 1], informally referred to as " fluoro ", is an imaging technique that uses X-rays to obtain real-time moving images of the interior of an object. In its primary application of medical imaging, a fluoroscope ( / ˈflʊərəˌskoʊp /) [ 2][ 3] allows a surgeon to see the internal structure and function of ...

  7. Renal cell carcinoma - Wikipedia

    en.wikipedia.org/wiki/Renal_cell_carcinoma

    Renal cell carcinoma ( RCC) is a kidney cancer that originates in the lining of the proximal convoluted tubule, a part of the very small tubes in the kidney that transport primary urine. RCC is the most common type of kidney cancer in adults, responsible for approximately 90–95% of cases. [ 1] It is more common in men (with a male-to-female ...

  8. Functional magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Functional_magnetic...

    Functional magnetic resonance imaging or functional MRI ( fMRI) measures brain activity by detecting changes associated with blood flow. [ 1][ 2] This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.

  9. 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 ...
