- n. An image produced on a radiosensitive surface, such as a photographic film, by radiation other than visible light, especially by x-rays passed through an object or by photographing a fluoroscopic image. Also called shadowgraph, skiagram, skiagraph.
- v. To make a radiograph of.
Century Dictionary and Cyclopedia
- n. An instrument for measuring and recording the intensity of solar radiation.
- n. An impression produced on a sensitized plate by X-rays or the radiations from radioactive substances. See ray and radioactivity.
- To produce an image of upon a sensitized plate by means of X-rays or the rays emitted from a radioactive substance.
- n. an image, often a photographic negative, produced by radiation other than normal light; especially an X-ray photograph
- v. To produce such an image
GNU Webster's 1913
- n. An instrument for measuring and recording solar radiation.
- n. An image or picture produced upon a sensitive surface, as of a photographic or fluorescent plate, by some form of penetrating radiation other than light, as X-rays, beta rays, etc.; esp., a picture of the internal structure of opaque objects traversed by the rays; a skiagraph. When the picture is produced upon photographic film by X-rays, the picture is usually called an
X-ray photoor X-ray. When an image is produced on photographic film by a radioactive substance in close proximity to the film, in a manner so as to record the spatial distribution of the radioactive substance, the resulting image is called an autoradiograph or autoradiogram.
- v. To make a radiograph of.
- n. a photographic image produced on a radiosensitive surface by radiation other than visible light (especially by X-rays or gamma rays)

“Gastric emptying via emesis or lavage should be performed in patients who have ingested greater than 40-60 mg./kg. of elemental iron or an unknown amount. 1 Activated charcoal is not useful, unless there are co-ingestants, since it does not bind metals such as iron. 1 Iron tablets are radiopaque, therefore, an abdominal radiograph should be performed to determine if there is evidence of iron tablets in the stomach or small bowel.”
“However, fetal lung lesions that seem to disappear on prenatal ultrasound and are not seen on neonatal chest radiograph still require evaluation by chest CT scan, which will frequently detect a lesion.”
“The researchers measured bone mineral content and density by dual-energy radiograph absorptiometry DXA.”
“This difference in body tissue density is why bone (high body tissue density) appears white on a radiograph, as compared to fat (low body tissue density), which appears gray or air (no density), which appears black.”
“An x-ray or radiograph is similar to having a photograph taken in a portrait studio.”
“The radiologic technologist (RT) will escort you to a dressing room where you will be given an examination gown (if necessary) and instructed to remove specific articles of your clothing that may interfere with the radiograph.”
“If is important that the radiograph is free of artifacts (e.g. material from your clothing, snaps, buttons, clips, etc ...).”
“The radiograph and the report become part of your medical record.”
“The BB patient typically had a radiograph with "dirty lungs", more sputum production and centrilobular emphysema and was more likely to be hypercapneic and develop right sided heart failure.”
“In an effort to pinpoint the trouble, Maria Travers, the assistant rehabilitation manager, took a radiograph image of the bird.”
