Permitting the passage of x-rays:
radiolucent
Aids physicians in performing ultrasound procedures:
sonographer
Transformation of stable substances into charged particles:
ionization
Radioactive drug administered for diagnostic purposes:
radiopharmaceutical
Radioactive chemical that gives off energy in the form of radiation:
radioisotope or radionuclide
A physician who specializes in diagnostic radiology:
radiologist
Study of the uses of radioactive substances in the diagnosis of disease:
nuclear
Radiopaque substances are given and conventional x-rays taken
contrast studies
Use of echoes of high-frequency sound waves to diagnose disease
ultrasonography
A magnetic field and radio waves are used to form images of the body
magnetic resonance imaging
X-ray pictures are taken circularly around an area of the body, and a computer synthesizes the information into composite images
computed tomography
Therapeutic procedures are performed by a radiologist under the guidance of CT, MRI, or ultrasonography

in vitro
process, test, or procedure in which something is measured or observed outside a living organism
in vivo
process, test, or procedure in which something is measured or observed in a living organism
radiopharmaceutical
radioactive drug (radionuclide plus chemical) that is given for diagnostic or therapeutic purposes
tracer studies
tests in which radioactive substance (radioisotopes) are administered with chemicals and followed as they travel throughout the body
uptake
the rate of absorption of a radionuclide into an organ or
tissue
perfusion lung scan
imaging technique in which a radiopharmaceutical is injected intravenously and traced within the blood vessels of the lung scanned
ventilation lung scan
imaging technique in which a radiopharmaceutical is inhaled and its passage through the respiratory tract is traced on a scan
bone scan
imaging technique in which a radiopharmaceutical is given
intravenously and taken up by bone tissue, followed by scanning to detect the amount of the radioactive substance in the bone
thyroid scan
imaging technique in which a radioactive substance is given orally and a scan (image) is made to assess its uptake in the thyroid gland
technetium Tc 99m Sestamibi scan
test of heart muscle function
gamma camera
machine that detects rays emitted by radioactive substances
positron emission tomography (PET)
radioactive glucose is injected and traced to body cells
radioisotope
a radioactive form (radionuclide) of a substance; gives off radiation
transducer
handheld device that sends and receives ultrasound signals
echocardiography
ultrasound is used to create an image of the heart
lymphoscintigraphy
nuclear medicine imaging of the lymphatic system
radioactive iodine uptake test
nuclear medicine test to evaluate the function of the thyroid gland
