Radiography

Medical Definition:	Examination of any part of the body for diagnostic purposes by means of roentgen rays, recording the image on a sensitized surface (such as photographic film).
Guide Notes:	GEN only: prefer /radiogr with organs & diseases: Manual 19.7+, 19.8.61; prefer also specific indentions in Cat E1; when GEN & IM, qualif permitted; Manual 26.4+; /educ = RADIOGRAPHY (IM) + RADIOLOGY /educ ; /man = RADIOGRAPHY (IM) + RADIOLOGY /man or TEC

Radiography Categories.

	Age Determination by Skeleton
	Angiography - Radiography of blood vessels after injection of a contrast medium.
	Arthrography - Roentgenography of a joint, usually after injection of either positive or negative contrast medium.
	Cineradiography - Motion picture study of successive images appearing on a fluoroscopic screen.
	Densitometry, X-Ray - Measurement of the degree of darkening of X-ray film by means of a photocell which measures light transmission through the film.
	Electrokymography - Radiographic technique combining a photoelectric recording system with fluoroscopy. It is used especially with electrocardiography to study heart motion.
	Fluoroscopy - Production of an image when x-rays strike a fluorescent screen.
	Hysterosalpingography - Radiography of the uterus and fallopian tubes after the injection of a contrast medium.
	Lymphography - Radiographic study of the lymphatic system following injection of dye or contrast medium.
	Mammography - Radiographic examination of the breast.
	Microradiography - Production of a radiographic image of a small or very thin object on fine-grained photographic film under conditions which permit subsequent microscopic examination or enlargement of the radiograph at linear magnifications of up to several hundred and with a resolution approaching the resolving power of the photographic emulsion (about 1000 lines per millimeter).
	Neuroradiography - Radiography of the central nervous system.
	Pneumoradiography - Radiography using air, oxygen, or some other gas as a contrast medium.
	Radiographic Magnification - Use of optic and geometric techniques to enhance radiographic image quality and interpretation. It includes use of microfocal X-ray tubes and intensifying fluoroscopic screens.
	Radiography, Abdominal - Radiographic visualization of the body between the thorax and the pelvis, i.e., within the peritoneal cavity.
	Radiography, Dental - Radiographic techniques used in dentistry.
	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.
	Radiography, Thoracic - X-ray visualization of the chest and organs of the thoracic cavity. It is not restricted to visualization of the lungs.
	Sialography - Radiography of the salivary glands or ducts following injection of contrast medium.
	Tomography, X-Ray - Tomography using x-ray transmission.
	Urography - Radiography of any part of the urinary tract.
	Xeroradiography - A photoelectric method of recording an X-ray image on a coated metal plate, using low-energy photon beams, long exposure time and dry chemical developers.
