What is Nuclear Medicine
uses very small amount of a radioactive substance to produce image
deals with force and charges
treatment for cancer
What are some advantages of Nuclear Medicine
Physiological Information, sensitive, very safe, give minimal radiation
Physiological Information, Quantitative, Low radiation exposure
All of the above
Radiopharmaceutical
Tc-99m
"trace" a particular physiology process in the body
gamma emission of suitable energy
All of the above
The amount of time necessary for a radionuclide to be reduced to half
half world
half life
Activity
What does alpha emission consists of?
two protons and 2 electrons
neutrino and alpha particle
2 protons and two neutrons
The process of neutron transformed into a proton with emission of electron and antineutrino
electron capture
gamma decay
beta emission
Isometric transition
inner orbital electrons is captured by a proton in the nucleus
energy is given off as gamma rays
excess energy of the nucleus is transmitted to one of the orbital
Intermediate excited state of an isotope
metatable
internal conversion
metastable
most commonly used radiopharmaceutical
Technetium-99m
Iodine-123
TI-201 thallium chloride
Iodine-131
used for thyroid gland studies
photon energy of 159 keV
half life 13 hours
has a shorter half life of 13 hours and photon energy of 159 keV which is a better option for thyroid imaging
Iodine-120
Iodine-131
Iodine-123
used for nuclear medicine imaging
SPECT and PET Scan
PET Scan
MRI
What kind of thyroid imaging is this
grave's disease
toxic adenoma
normal
myocardial perfusion imaging clinical indications
diagnosis of urinal artery disease
assessment after percutaneous transluminal coronary bypass grafting
none of the above
this indicates the evaluation of osseous metastatic disease
renal imaging
bone imaging
either
PET Scan
detects gamma rays emitted indirectly by a positron emitting radiopharmaceutical
three-dimensional images
used to observe metabolic processes in the body
all of the above
which of the following are clinical indication for PET Scan (may select multiple choices)
Cancer imaging
Treatment
Neurology and Cardiology
Therapy
Cancer cells have a higher level of metabolic activity than normal tissues and use more glucose
True
False
Radionuclides for therapy
given orally, intravenously or placed directly to bod cavity
predominantly alpha emitters
emits more gamma rays
This is a normal PET Scan
False
True
