nuclear medicine - answer uses radioactive materials
-radiopharmaceuticals
organ/tissue function - answer Nuclear medicine studies determine causes based on
what function?
tracer - answer is introduced into the body by injection, swallowing, or inhalation.
tracer - answer are selected on the basis of the organ to be examined.
therapeutic goal - answer amount of tracers used is based on what?
gamma-ray - answer Radioactive tracers produce ____-_____ emissions from within
the organ being studied.
scintillation camera - answer A gamma, or _____ camera, is used to transform these
emissions into images that provide information about the function and anatomy of the
organ or system being studied.
nuclear medicine physician
nuclear medicine technologist
physicist
pharmacist - answer Nuclear medicine test are performed by what educated
professionals?
John Dalton - answer is considered the father of the modern theory of atoms and
molecules.
Wilhelm Roentgen - answer The discovery of x-rays by ____ _____ in 1895 was a
great contribution to physics and the care of the sick.
Henri Becquerel - answer discovered naturally occuring radioactive substances.
Marie Curie - answer in 1898 ____ _____ discovered two new elements in uranium
ore. These terms were coined as radioactive and radioactivity.
polonium and radium - answer Curie named these trace elements what?
, George de Hevesy - answer in 1923, often called the "father of nuclear medicine,"
developed the tracer principle. He coined the term radioindicator and extended his
studies from inorganic to organic chemistry. The first radioindicators were naturally
occurring substances such as radium and radon.
cyclotron - answer What did Ernest Lawrence invent?
Enrico Fermi - answer who developed nuclear reactors.
Hal Anger - answer introduced the gamma camera.
David Edwards & Roy Kuhl - answer developed the SPECT camera:
-MARK IV
-Created 3D images of organ function
-Standard practice in the 1980's
F.W. Wrenn: - answer demonstrated use of positron-emitting radioisotopes
G. Brownell - answer developed instrumentatiion for further study
Hounsfield - answer demonstrated clinical use of computed tomography.
Microprocessors - answer now tune and adjust the entire ring of detectors that
surround the patient. Each ring may contain as many as 1000 detectors.
PET - answer was routinely used for diagnostic procedures on the brain, heart, and
tumors.
septa - answer The midde to late 1990s saw the development of three-dimensional
PET systems that eliminated the use of interdetector ___.
This allowed the injected dose of the radiopharmaceutical to be reduced up to 10 times
its strength.
thyroid - answer was one of the first organs to be examined by nuclear medicine
using external radiation detectors.
Nuclear medicine - answer is predominantly used to measure human cellular, organ,
or system function.
conventional radiography - answer measures the structure, size, and position of
organs or human anatomy by determining x-ray transmission through a given volume of
tissue.
computed tomography - answer creates cross-sectional images by computer
reconstruction of multiple x-ray transmissions.
