|
89 Sr
90 Y |
|
|
what is 89 Sr used for
|
bone paliation associated w/ bone cancer. may cause bone marrow toxicity
|
|
|
what is 90 Y used for
|
radioimmunotherapy of solid large tumors and lymphomas, soft tissue palliation
|
|
|
what are the radiodiagnostic agents
|
99m Tc
111 In 123 I |
|
|
what is 99m Tc used for
|
offers fast and clear imaging
|
|
|
what is 111 In used for
|
allows multiple images
stays in body longer so dont have to use as many doses forms stable complexes with antigen specific monoclonal antibodies |
|
|
what does 123 I do
|
superior for thyroid gland imaging and accumulates passively
more expensive than 99m Tc or 131 I |
|
|
what is used for mixed diagnostic/radiotherapeutic agent
|
131 I
|
|
|
what does 131 I do
|

incorporated w/ organic molecules for imaging myocardial and cerebral metabolism
|
|
|
what is N 13 used for
|
tracing cerebral and myocardial blood flow as well as viewing pulmonary ventillation
|
|
|
what is O15 used for
|
imaging oxygen metabolism, RBC volume, regional blood flow, cerebral and myocardial perfusion
|
|
|
what is F 18 used for
|
offers specific activity for receptor specific tracer binding
|
|
|
what is the purpose of incorporating a foreign label
|
EX: 99m Tc must be chelated with the compound of interest in order to limit its toxicity and increase its excretion of radioactive material FROM the body over time
|
|
|
how do you treat radiation exposure
|
1)remove the source
2) contain the area of contamination 3) reduce bodily exposure 4) wash the victim with soap 5) if ingested, induce vomiting, pump stomach or activated charcoal |
