Question | Answer |
cineradiography | use of motion picture techniques to record a series of x-ray images during fluoroscopy |
computed tomography (CT) | diagnostic x-ray procedure whereby a cross-sectional image of a specific body segment body segment is produced |
contrast studies | materials (contrast media) are injected to obtain contrast with surrounding tissue when shown on the x-ray film |
fluorescence | emission of glowing light results from exposure to and absorption of radiation from x-rays |
fluoroscopy | x-ray technique that produces a fluorescent image on an image intensifier |
gamma camera | machine to detect gamma rays emitted from radiopharmaceuticals 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 |
interventional radiology | therapeutic procedures performed by a radiologist |
in vitro | process, test, or procedure is performed, measured, or observed outside a living organism |
in vivo | process, test, or procedure is performed, measured, or observed within a living organism |
ionization | transformation of electrically neutral substances into electrically charged particles |
labeled compound | radiopharmaceutical; used in nuclear medicine studies |
magnetic resonance imaging (MRI) | magnetic field and radio waves produce sagittal, coronal, and axial images of the body |
nuclear medicine | medical specialty that studies the ises of radioactive substances (radionuclides) in diagnosis of disease |
positron emission tomography (PET) | positron-emitting radioactive substances given intravenously create a cross-sectional image of cellular metabolism based on local concentration of the radioactive substance; give information about organ function |
radioimmunoassay | test combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient's blood |
radioisotope | radioactive form of an element substance; radionuclide |
radiology | medical specialty concerned with the study of x-rays and their use in the diagnosis of disease; includes other forms of energy, such as ultrasound and magnetic waves |
radiolucent | permitting thhe passage of x-rays. structures appear black on x-ray film |
radionuclide | radioactive form of an element that gives off energy in the form of radiation; radioisotope |
radiopaque | obstructing the passage of x-rays. structures appear white on the x-ray film |
radiopharmaceutical | radioactive drug (radionuclide plus chemical) that is administered safely for diagnostic and therapeutic purposes |
roentgenology | study of x-rays; radiology |
scan | image of an area, organ or tissue in the body obtained from ultrasound, radioactive tracer studies, CT, or MRI |
single photon emission computed tomography (SPECT) | radioactive tracer is injected intravenously and a computer reconstructs a 3D image based on a composite of many views |
tagging | attaching a radionuclide to a chemical and following its path in the body |
tracer studies | radionuclides are used as tags, or labels, attached to chemicals and followed as they travel through the body |
transducer | handheld device that sends and receives ultrasound signals |
ultrasonography (US, U/S) | diagnostic technique that projects and retrieves high-frequency sound waves as they echo off parts of the body |
uptake | rate of absorption of a radionuclide into an organ or tissue |
ventilation-perfusion studies | radiopharmaceutical is inhaled (ventilation) and injected intravenously (perfusion) followed by imaging its passage through the respiratory tract |
