| radiographic parallel line shadows | The images of bronchial walls, usually thickened; colloq., British. Synonym: radiographic parallel line shadows. (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) |
| radiography, thoracic | X-ray visualization of the chest and organs of the thoracic cavity. It is not restricted to visualization of the lungs. (12 Dec 1998) |
| radiohumeral | Relating to the radius and the humerus; denoting the articulation between them. (05 Mar 2000) |
| radioimmunity | Lessened sensitivity to radiation. (05 Mar 2000) |
| radioimmunoassay | <investigation, technique> Any system for testing antigen antibody reactions in which use is made of radioactive labelling of antigen or antibody to detect the extent of the reaction. (18 Nov 1997) |
| radioimmunodetection | Use of radiolabelled antibodies for diagnostic imaging of neoplasms. Antitumour antibodies are labelled with diverse radionuclides including iodine-131, iodine-123, indium-111, or technetium-99m and injected into the patient. Images are obtained by a scintillation camera. (12 Dec 1998) |
| radioimmunodiffusion | A method for the study of antigen-antibody reactions by gel diffusion using radioisotope-labelled antigen or antibody. (05 Mar 2000) |

| radioisotopic culture |
a bacterial culture in a medium containing 1 4 C-labeled carbohydrate. Metabolism is detected by the release of 1 4 CO 2 , offering earlier detection of growth than do conventional methods.

| radio frequency |
1. (Abbreviated RF.) The number of oscillations per second of the electric and magnetic fields in the radio portion of the electromagnetic spectrum, generally that portion between 10 4 and 10 12 Hz; specifically, the frequency of a given radio carrier wave. 2. In radio or radar, pertaining to a signal at the transmitted or received frequency, as opposed to a signal translated to a different frequency (IF signal) or detected (video signal).

| radiant |
1. Pertaining to the emission or the measurement of electromagnetic radiation. Compare luminous. 2. In describing auroras, a projected point of intersection of lines drawn coincident with auroral streamers, that is, the point from which the aurora seems to originate.

| radiometry |
The technique of measuring radiant energy, especially radiant energy in that portion of the total electromagnetic spectrum lying adjacent to the visible region. Radiometry is to be distinguished from the closely related subject of photometry, the latter being specifically concerned with the quantitative response to visible radiation of the human eye. See actinometer.
