| angiography, digital subtraction | A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitised image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues. (12 Dec 1998) |

| subtraction | 1. The act or operation of subtracting or taking away a part. 2. <mathematics> The taking of a lesser number or quantity from a greater of the same kind or denomination; an operation for finding the difference between two numbers or quantities. 3. The withdrawing or withholding from a person of some right to which he is entitled by law. Thus the subtraction of conjugal rights is when either the husband or wife withdraws from the other and lives separate without sufficient reason. The subtraction of a legacy is the withholding or detailing of it from the legatee by the executor. In like manner, the withholding of any service, rent, duty, or custom, is a subtraction, for which the law gives a remedy. Origin: L. Subtractio a drawing back. See Subtract, and cf. Substraction.

| subtraction technique | Combination or superimposition of two images for demonstrating differences between them (e.g., radiograph with contrast vs. One without, radionuclide images using different radionuclides, radiograph vs. Radionuclide image) and in the preparation of audiovisual materials (e.g., offsetting identical images, colouring of vessels in angiograms). (12 Dec 1998) |
| digital subtraction angiography | Computer-assisted roentgenographic angiography permitting visualization of vascular structures without superimposed bone and soft tissue density; images made before and after contrast injection allow subtraction (separation and removal) of opacities not enhanced by the contrast medium. Other image-processing can be performed. Contrast material may be injected intravenously or in lower-than-usual amount intra-arterially. (05 Mar 2000) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| air-gap radiography | Chest radiography with a space (at least 10 inches) between the subject and film. Instead of using a grid, this method uses the geometry and X-ray absorption by the air to remove scattered radiation. (05 Mar 2000) |
| bedside radiography | Making radiographic films of a patient confined to bed by taking a movable X-ray machine to the room. Synonym: bedside radiography. (05 Mar 2000) |
| radiography | <investigation, procedure> The making of film records (radiographs) of internal structures of the body by passage of X-rays or gamma rays through the body to act on specially sensitised film. Origin: Gr. Graphein = to write (18 Nov 1997) |
| radiography, abdominal | Radiographic visualization of the body between the thorax and the pelvis, i.e., within the peritoneal cavity. (12 Dec 1998) |
| radiography, bitewing | Technique involving the passage of X-rays through oral structures to create a film record while a central tab or wing of dental X-ray film is being held between upper and lower teeth. (12 Dec 1998) |
| radiography, dental | Radiographic techniques used in dentistry. (12 Dec 1998) |
| radiography, dental, digital | A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from X-ray film or any other detector. (12 Dec 1998) |
| radiography, dual-energy scanned projection | A method of producing a high-quality scan by digitizing and subtracting the images produced by high- and low-energy X-rays. (12 Dec 1998) |
| radiography, interventional | Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization. (12 Dec 1998) |
| radiography, panoramic | Extraoral body-section radiography depicting an entire maxilla, or both maxilla and mandible, on a single film. (12 Dec 1998) |
