Med Term- Module 5 Flashcards
angiography
X-ray imaging of blood vessels after injection of contrast material
arthrography
X-ray imaging of a joint after injection of contrast material
cholangiography
X-ray recording of the biliary system performed after injection of contrast into the bile ducts
digital subtraction angiography
video equipment, computer, and x-ray machine produce images of blood vessels before and after injecting contrast material
hysterosalpingography
X-ray procedure used to view the inside of the uterus and fallopian tubes
myelography
X-ray image of the spinal cord after injection of contrast into the membranes surrounding the spinal cord
pyelography
X-ray recording of the kidneys and urinal tract after contrast is injected
cineradiography
process of making radiographs of moving objects (heart and joints)
contrast studies
Diagnostic x-ray procedure whereby a cross-sectional image of a specific body segment is produced
computed tomography
cross-sectional x-ray imaging of an organ with or without contrast material
fluorescent
luminescence that is caused by the absorption of radiation of one wavelength
gamma camera
machine to detect gamma rays emitted from radiopharmaceuticals during scanning for diagnostic purposes
gamma rays
high-energy rays emitted by radioactive substances used in tracer studies
half-life
time required for a radioactive substance to lose half its radioactivity by disintegration
interventional radiology
therapeutic or diagnostic procedures performed by a radiologist
in vitro
process, test, or procedure is performed, measured, or observed outside a living organism, often in a test tube
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
magnetic resonance
magnetic waves and radio waves produce images of organs and tissues in all three planes of the body
nuclear medicine
medical speciality that uses radioactive substances in the diagnosis and treatment of disease
positron emission tomography
positron-emitting radioactive substances given intravenously create a cross-sectional image of cellular metabolism based on local concentration of the radioactive substance
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
radiolucent
permitting the passage of x-rays
radionuclide
radioactive form of an element that gives off energy in the form of radiation
radiopaque
obstructing the passage of x-rays
radiopharmaceutical
radioactive drug that is administered safely for diagnostic and therapeutic purposes
scan
image of an area, organ or tissue of the body obtained from ultrasonography, radioactive tracer studies, computed tomography, or magnetic resonance imaging
scinitigraphy
diagnostic nuclear medicine test using radiopharmaceuticals and gamma cameras to create images
single photon emission computed tomography
radiocative 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
ultrasonography
diagnostic technique that uses high-frequency sound waves to produce images of the body
uptake
rate of absorption of a radionuclide into an organ or tissue
ventilation-perfusion study
consists of two scans; a ventilation scan performed using an inhaled radiopharmaceutical and a perfusion scan using an intravenously injected radiopharmaceutical
