NUCLEAR MEDICINE Flashcards
branch of medicine that uses radioactive substances in diagnosis and therapy
nuclear medicine
these substances consist of pharmaceuticals labelled with radioisotopes “________”
radiopharmaceuticals
in diagnosis, radioactive substances are administered to patient and the radiation emitted is measured and location recorded
true or false
true
in therapy, radioisotopes are administered to treat disease
true or false
true
it use a carrier molecule, selected to target the organ/tissue of interest, tagged with radioisotopes which is emitting gamma ray
nuclear medicine technique
radiology is also called as
xray radiation
is a medical specialty that involves using medical imaging technology to take pictures of the muscles, bones, ad organs
radiology
a type of medical imaging that uses nuclear compounds and radioactive materials to observe chemical interactions inside the body and inspect organs and bones
nuclear medicine
it creates images using internal radiation waves from inside the body
nuclear medicine
it develops images and apply external energy waves to the body
radiology
the routes of administration for radioactive substances includes ___
intravenous injection
subcutaneous injection
inhalation
ingestion
the radioactive substances is injected to a vein
intravenous injection
radioactive substances is injected under the skin
subcutaneous injection
some radioactive substances radioisotopes are inhaled by the patient
inhalation
radioactive substances can be ingested
ingestion
the radioactive materials administered to patients are known as
radiopharmaceuticals
radiopharmaceuticals are consists of
chemical molecule which determines the behavior of the radiopharmaceutical in the body
the radiation emitted by the radionuclide may be detected from outside the body by a radionuclide imaging device (a gamma camera) or may be detected in a sample of a body fluid (e.g. plasma or urine)
radionuclide must have certain properties such as
emit only gamma radiation
emit gamma ray with the right energy (120 kec - 300 kev) to allow detection by a gamma camera
have a short half-life
be cheap
be readily available
examples of radionuclide, half life and the target tissues
technetium
6 hrs
salivary gland, thyroid, bone, blood, lover, lung, heart
examples of radionuclide, half life and the target tissues
iodine
8 days - thyroid
examples of radionuclide, half life and the target tissues
gallium
78 hours
tumors and inflammation
is an electronic device used in medical diagnosis for imaging the distribution of radioactive compounds in the tissues
gamma camera
it is a devie used for imaging in nuclear medicine for imaging the gamma rays emanating from the radioactive compounds in the body
gamma camera
