adduction | Movement toward the midline of the body. |
angiogram | X-ray image of blood vessels after injecting contrast material into the vessels. |
anteroposterior | In this AP x-ray view, x-rays travel from an anteriorly placed source to a posteriorly placed detector (x-ray beam passes from the front to the back of the body). |
arthrography | Process of x-ray imaging a joint after injecting contrast into the joint. |
bone scan | A radioactive (technetium-99m) phosphate compound is injected intravenously and bones are scanned for evidence of tumors. |
cholangiography | Process of x-ray imaging bile ducts after injecting contrast into the bile ducts. |
cineradiography | Use of motion picture techniques to record a series of x-ray images. |
computed tomography | Use of x-ray equipment and a computer to create multiple views of organs, including cross-sectional or axial images. |
contrast studies | Material (contrast media) is injected into vessels and organs to obtain contrast with surrounding tissues when viewed on x-ray and other mages. |
echocardiography | Sound waves are used to image the structure of the heart. |
eversion | Turning outward. |
extension | Lengthening or straightening a flexed limb. |
flexion | Bending a part of the body. |
fluorescence | Emission of glowing light that results from exposure to and absorption of radiation from x-rays. |
fluoroscopy | Process of using x-rays to produce an image on a fluorescent screen. |
gallium scan | Radioisotope (gallium 67) is injected intravenously and has an affinity for tumors and other lesions. |
gamma camera | Machine to detect gamma rays given off by radiopharmaceuticals (radioactive compounds) during scanning for diagnostic purposes. |
gamma rays | High-energy rays emitted by radioactive substances in tracer studies. |
half-life | Time required for a radioactive substance to lose half its radioactivity by disintegration. |
in vitro | Process, test, or procedure performed, measured, or observed outside a living organism. |
in vivo | Process, test or procedure performed, measured, or observed within a living organism. |
interventional radiology | Therapeutic procedures performed by a radiologist. |
inversion | Turning inward. |
ionization | Transformation of electrically neutral substances into electrically charged particles. |
labeled compound | Combination of a radioactive substance (radionuclide) and a drug; used in nuclear medicine studies. |
lateral decubitus | Lying down on one’s side with the x-ray beam horizontally positioned. |
magnetic resonance imaging | Magnetic field and radio waves produce sagittal, coronal, and axial images of the body; especially effective to image soft tissues. |
myelography | X-ray image of the spinal cord after injection of contrast into the membranes surrounding the spinal cord. |
nuclear medicine | Medical specialty that studies the uses of radioactive substances (radionuclides and radiopharmaceuticals) in the diagnosis of disease. |
oblique | Positioned at an angle; an x-ray view. |
positron-emission tomography (PET) | Radionuclides given intravenously emit positrons, which create a cross-sectional image of cellular metabolism in specialized areas of the body. |
posteroanterior | In this position, x-ray beams pass from the back to the front of the body. |
prone | Lying on the belly (face down). |
pyelogram | X-ray record of the kidneys (renal pelvis) and urinary tract after contrast is injected (intravenously or retrograde). |
radiographer | Aids physicians in administering diagnostic x-ray procedures. |
radioimmunoassay | Test combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient’s blood. |
radioisotope | Radioactive form of an element; radionuclide. |
radiology | Study of x-ray and other energy sources in the diagnosis of disease. |
radiolucent | Permitting the passage of x-rays. |
radionuclide | Radioactive form of an element; gives off energy in the form of radiation; radioisotope. |
radiopaque | Obstructing the passage of x-rays. |
radiopharmaceutical | Radioactive drug (radionuclide plus a drug) that is administered safely for diagnostic and therapeutic purposes. |
recumbent | Lying down (prone or supine). |
roentgenology | Study of x-rays; radiology. |
scan | Image of an area, organ, or tissue of the body obtained from ultrasound, radioactive tracer studies, or computed tomography. |
single photon emission computed tomography (SPECT) | Radioactive tracer is injected intravenously, and a computer reconstructs a three-dimensional image based on a composite of many views. |
sonogram | Image of sound waves as they bounce off organs in the body; echogram or ultrasound image. |
supine | Lying on one’s back. |
tagging | Attaching a radionuclide to a chemical and following its path in the body. |
thallium scan | Thallium 201 is injected intravenously to allow for myocardial perfusion and assess damage to heart muscle from heart attacks. |
therapeutic | Pertaining to treatment or therapy. |
thyroid scan | An iodine 131 radionuclide is administered intravenously, and an image of the size and shape of the thyroid gland is obtained by scanning. |
tomography | Process of taking a series of images to show an organ in layers or depth. |
tracer studies | Radionuclides are attached to chemicals, used as tags or markers, and followed as they travel through the body. |
transducer | Handheld device that sends and receives ultrasound signals. |
ultrasonography | Ultrasonography is the use of high frequency sound waves that are beyond the range of normal hearing to produce a record or picture of an organ or tissue. |
ultrasound | Diagnostic technique that projects and retrieves high-frequency sound waves as they bounce (echo) off parts of the body. |
uptake | Rate of absorption of a radionuclide into an organ or tissue. |
urography | Process of taking x-ray images of the urinary tract after injecting contrast. |
