This PET radiopharmaceutical is metabolized as a glucose analog
What is 18F-fluorodeoxyglucose (FDG)
This is the typical unit to describe radiation exposure
What is "the roentgen (R)"
These two devices are capable of producing positron-emitting radionuclides
what are "cyclotrons" and "linear accelerators"
In the correct order, this radiopharmaceutical is a sodium salt analog and this radiopharmaceutical is a glucose sugar analog
What are 18F-NaF and 18F-FDG
The positron shares all physical characteristics with this subatomic particle except for an equal yet opposite charge
What is an electron
This PET radionuclide has a half-life of 75 seconds and is an analog of potassium
What is 82Rubidium
This concept applies equitably to all types of materials and all types of radiation, and is quantified by the unit gray (Gy)
What is the "absorbed dose"
Proton-rich nuclei are created by bombarding a target atom with either of these two charged subatomic particles
What are protons and deuterons
Standard uptake of this radiopharmaceutical includes the liver
What is 18F-FDG, or "sweet"
Positron decay is possible in this nuclear environment, according to the chart of nuclides "line of stability"
What is "proton-rich"
The process by which 18F-sodium fluoride (NaF) is incorporated into the hydroxyapatite crystalline lattice of the calcified bone matrix
What is "chemisorption"
The bladder, in terms of 18F-FDG imaging
What is the "critical organ"
This PET radionuclide can be produced by the following reaction: 18O(p,n)__
What is 18Fluorine
Hydration and frequent urination are recommended in conjunction with this radiopharmaceutical
What is 18F-NaF, or "bitter"
Given the appropriate nuclear environment, positron decay is complemented by the possibility of which other decay process
What is "electron capture"
This PET radiopharmaceutical is incorporated into glutamine by glutamine synthetase, making it a useful agent for myocardial perfusion imaging
What is 13N-NH3 ammonia
Stand-alone 18F-FDG PET procedures render an only slightly greater effective dose than this other, very common nuclear medicine procedure
What is a 99mTc-based Myocardial Perfusion Study
This PET radionuclide generator is required to be bedside during MPI procedures due to the tracer's 75sec T1/2
What is the CardioGen-82
This procedure does not require any fasting and all medications may be taken prior to exam
What is 18F-NaF, or "bitter"
This is the minimum energy requirement (in keV) for a radionuclide to undergo positron decay
What is 1,022keV
Phosphoglucose isomerase (PGI) cannot do this to 18F-FDG, which keeps it from further metabolism, allowing it to remain trapped in the cell for useful imaging
What is "alter from a 5-carbon glucose-6-phosphate to a 4-carbon fructose-6-phosphate structure"
The addition of this component increases the 18F-FDG total effective dose of ~9mSv to typically over 24mSv
