Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by gamma cameras, which are external detectors that form two-dimensional images [1] in a process similar to the ...
Also called the Blue Dog Democrats or simply the Blue Dogs. A caucus in the United States House of Representatives comprising members of the Democratic Party who identify as centrists or conservatives and profess an independence from the leadership of both major parties.

Some studies require the labeling of a patient's own blood cells with a radionuclide (leukocyte scintigraphy and red blood cell scintigraphy). Most diagnostic radionuclides emit gamma rays either directly from their decay or indirectly through electron–positron annihilation , while the cell-damaging properties of beta particles are used in ...
Former President Richard Nixon secured the term into the political lexicon, albeit with a different meaning, with his "Silent Majority" speech on Nov. 3, 1969, requesting support for the Vietnam ...
An example of lung scintigraphy examination. A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy.
So, after a week of living through ever-more interesting times, we thought a little silliness might be appreciated, which is why we've created the 538 political dogs (or "polidogs") quiz!
Bellwether. Continuing resolution. Ranked-choice voting. Bound delegate. These are just a few of the terms frequently used in political news coverage. But do you know what they mean?
Dacryoscintigraphy (DSG), also known as lacrimal scintigraphy, is a nuclear medicine technique for imaging the lacrimal apparatus. It is used to identify obstructions, for example in the lacrimal duct , nasal cavity or nasolacrimal duct .
