radiography

 [ra″de-og´rah-fe]
the making of film records (radiographs) of internal structures of the body by exposure of film specially sensitized to x-rays or gamma rays. adj., adj radiograph´ic.
body section radiography tomography.
double-contrast radiography mucosal relief radiography.
electron radiography radiography consisting of electronic images that can be computer enhanced, electronically reversed, stored, retrieved, transmitted, and/or printed on photographic film.
mass radiography examination by x-rays of the general population or of large groups of the population.
mucosal relief radiography a technique for revealing any abnormality of the intestinal mucosa, involving injection and evacuation of a barium enema, followed by inflation of the intestine with air under light pressure. The light coating of barium on the inflated intestine in the radiograph reveals clearly even small abnormalities; double-contrast r.
neutron radiography that in which a narrow beam of neutrons from a nuclear reactor is passed through tissues; especially useful in visualizing bony tissue.
panoramic radiography pantomography.
serial radiography the making of several exposures of a particular area at arbitrary intervals.
spot-film radiography the making of localized instantaneous radiographic exposures; see also spot film.

ra·di·og·ra·phy

(rā'dē-og'ră-fē),
Examination of any part of the body for diagnostic purposes by means of x-rays with the record of the findings usually exposed onto photographic film.
Synonym(s): roentgenography

radiography

/ra·di·og·ra·phy/ (ra″de-og´rah-fe) the making of film records (radiographs) of internal structures of the body by passing x-rays or gamma rays through the body to act on specially sensitized film.radiograph´ic
body section radiography  tomography.
digital radiography  a technique in which x-ray absorption is quantified by assignment of a number to the amount of x-rays reaching the detector; the information is manipulated by a computer to produce an optimal image.
electron radiography  a technique in which a latent electron image is produced on clear plastic by passing x-ray photons through a gas with a high atomic number; this image is then developed into a black-and-white picture.
mucosal relief radiography  radiography of the mucosa of the gastrointestinal tract in a double-contrast examination.
neutron radiography  that in which a narrow beam of neutrons from a nuclear reactor is passed through tissues, especially useful in visualizing bony tissues.
serial radiography  the making of several exposures of a particular area at arbitrary intervals.
spot-film radiography  the making of localized instantaneous radiographic exposures during fluoroscopy.

radiography

(rā′dē-ŏg′rə-fē)
n.
The process by which radiographs are made. Also called skiagraphy.

radiography

[rā′dē·og′rəfē]
Etymology: L, radius + Gk, graphein, to record
the production of shadow images on photographic emulsion through the action of ionizing radiation. The image is the result of the differential attenuation of the radiation in its passage through the object being radiographed. radiographic, adj.

radiography

Roentgenography, radiographic imaging Imaging The recording of an image of a region placed in a beam of radiation. See Angiography, Cholangiography, CT imaging, Fluoroscopy, GI series, IVP, Mammography, MRI, Venography, Xeroradiography.

ra·di·og·ra·phy

(rā'dē-og'ră-fē)
Examination of any part of the body for diagnostic purposes by means of x-rays with the record of the findings usually impressed on a photographic film.

radiography

The use of X-radiation to produce images that can help in diagnosis. Radiography includes the use of CT SCANNING, which is an X-ray technique,RADIONUCLIDE SCANNING and, by courtesy, magnetic resonance imaging (MRI). Compare RADIOLOGY.

Radiography

Examination of any part of the body through the use of x rays. The process produces an image of shadows and contrasts on film.

ra·di·og·ra·phy

(rā'dē-og'ră-fē)
Examination of any body part for diagnostic purposes with x-rays with the record of the findings exposed onto photographic film.

radiography

the making of film records (radiographs) of internal structures of the body by exposure of film specially sensitized to x-rays or gamma rays.

body-section radiography
a special technique to show in detail images and structures lying in a predetermined plane of tissue, while blurring or eliminating detail in images in other planes; various mechanisms and methods for such radiography have been given various names, e.g. laminagraphy, tomography, etc.
contrast radiography
the use of means of exaggerating the differences in density of tissues or organs or intraluminal filling defects, usually by the introduction of contrast agents.
double contrast radiography
see double contrast.
intraoral radiography
small non-screen film is placed in the mouth and x-rays are directed from outside the mouth. Used to assess alveolar bone and roots of teeth.
mucosal relief radiography
a technique for revealing any abnormality of the intestinal mucosa, involving injection and evacuation of a barium enema, followed by inflation of the intestine with air under light pressure. The light coating of barium on the inflated intestine in the radiograph reveals clearly even small abnormalities.
neutron radiography
that in which a narrow beam of neutrons from a nuclear reactor is passed through tissues; especially useful in visualizing bony tissue.
scout radiography
see survey radiograph, straight (2).
serial radiography
the making of several exposures of a particular area at arbitrary intervals.
spot-film radiography
the making of localized instantaneous radiographic exposures during fluoroscopy.
stress radiography
positioning to intentionally place stress on structures being radiographed; most commonly used in the diagnosis of spinal disorders such as atlantoaxial instability, wobbler syndrome and lumbosacral instability.
