what is the medical specialty that studies the characteristics and uses of radioactive substances in diagnosis of disease
which x-ray view is the patient upright with the back to the x-ray machine and the film to the chest
perfusion study of the lung
which test is radiopharmaceutical injected intravenously and traced within the vessels of the lung
psitron emission tomography
radioactive substance is given intraveneously and a cross-sectional image is created of cellular metabolism based on local concentration of the radioactive substance
x-ray beams are focused from the body onto an image intensifier that glows as a result of the ionizing effect of x-rays
x-ray pictures are taken circularly around an area of the body and a computer synthesizes the information into a composite axial picture
theraputic procedures are performed by radiologist under the guidance of fluoroscopy or ultrasound
radioactive drug that is administered safley for diagnostic and theraputic purposes
imaging technique in which a radiopharmeceutical is given intravenously and taken up by bone tissue followed by scanning to detect the amount of radioactive substance
positron emission tomography
radioactive substances produce cross-sectional images of regions of the body
diagnostic x-ray procedure in which cross-sectional images are made of specific body segments
radionuclides are used as tags attached to chemicals and followed throughout the body
time required for a radioactive substance to lose half its radioactivity by disintergration
diagnostic x-ray procedure whereby a cross-sectional and other images of a specific body segment are produced
materials are injected to obtain contrast with surrounding tissue when shown on x-ray film
materials to detect gamma rays emitted from radiopharmaceauticals during scanning for diagnostic purposes
test that combines radioactive chemicals and antibodies to detect minute quantities of substances in a patients blood
