RADIOLOGY AND NUCLEAR MEDICINE
STUDY
PLAY
computed tomography
CT scan
contrast studies
radiopaque materials are injected to obtain contrast with surrounding tissuewhen shown on x-ray film
gamma camera
machine to detect gamma rays emitted from radiopharmaceuticals during scanning for diagnostic purposes
gamma rays
high energy rays emitted by radioactive substances inn 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
in an artificial environment outside the living organism
in vivo
within a living organism
ionization
the process of ionizing
magnetic resonance imaging
magnetic field and radio waves produce sagittal, coronal,and axial images of the body
nuclear medicine
medical specialty that studies the uses of radioactive substances (radionuclides) in diagnosis of disease
position emission tomography
PET scans give information about metabolic activity
radioimmunoassay
test combines radioactive chemicals and antibodies to detect minute quanities of substances in a patients blood
radioisotope
radioactive form of an element substance: radionuclide
radiolabeled compound
radiopharmaceutical
radiology
the study of x-rays and their use in the diagnosis of disease
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 a ultrasound,radioactive tracer studies, computed tomography, or magnetic resonance imaging
single photon emission computed tomography (spect)
radioactive tracer is injected intravenously and a computer reconstructs a 3D image based on a computer with many views
tagging
attaching a radionuclides 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
