Nuclear Medicine

Hscu 209

QuestionAnswer
Radiopharmaceuticals Radioactive materials used for diagnosis, therapy and medical research
Radiopharmaceuticals methods of administration Can be injected, ingested or inhaled
Nuc med visiualizes what Do not visualize structures but demonstrate function
5 radionuclides used technetium iodine indium thallium gallium
Isotopes are Elements with the same number of protons but a different number of neutrons in the nucleus
Isotopes have the same chemical properties as one another because the total number or protons and neutrons is the same
Isotopes differ in the total number of neutrons contained in the nucleus
What determines the stability in an atom The neutron-to-proton ratio in the nucleus
Radionuclide decay The emission of alpha, beta and gamma radiation
Radionuclide decay reach ground state through alpha, beta and positron emission and electron capture
The decay process determines the type of particles or gamma rays given off in the decay
Half life The probability of a particular decay process and the rate of change into the ground state element is known as half-live T½
Half life range from ms to years
Half-live of radionuclides used in N.M. range from several hours to several days
Tracer A radioactive material introduced into the body
Tracers are selected by how they localize in specific organs or tissues
The amount of tracer used provides the least radiation exposure to the patient that can provide a satisfactory exam or therapeutic goal
Radioactive traces produce Gamma ray emission
2 types of cameras for NM Gamma or Scintillation Camera
3 PET scans heart, brain, and lungs
What kind of decay does PET use positron
SPECT 3 Single Photon Emission Computer Tomography; Employs collimators and low-energy photons It is less sensitive and less accurate than PET
Unlike xray, in NM radionuclides emit radiation before and after administration
