What is nuclear medicine?
|
A medical specialty that utilizes radiopharmaceuticals to assist in the diagnosis and treatment of disease.
|
|
What are radiopharmaceuticals?
|
radioactive drugs
|
|
What is the "Tracer Principle"?
|
radiopharmaceuticals used for diagnostic purposes are expected to be present in such low concentrations that they don't have any effect on the body.
|
|
What is specific activity?
|
amount of radioactivity per unit mass
|
|
Why is high specific activity needed for radiopharmaceuticals?
For what procedure is this particularly important and why? |
to maintain the tracer principle:
high specific activity allows the drug to be given in trace amounts to diagnose without negative physical effects particularly important for PET b/c the drug gets in the brain |
|
What are the three ways specific activity is affected?
|
Carrier-free
Carrier-added No carrier added |
|

|
What is meant by "carrier added"?
|
radioisotope has been diluted with stable isotope of that element
- used in mass balance studies (Phase I research) |
|
What is meant by "no carrier added"?

|
|
|
What are the two methods of acquiring radio images?
|

|
What is "dynamic imaging"?
|
A detector placed over the organ of interest prior to administration of radiopharmaceutical captures the rate of acccumulation and excretion through images.
|
|
What is "static imaging"?
|
A detector placed over the organ of interest after administration of radiopharmaceutical shows the extent of accumulation.
|
|
What is a "Schilling's Test"?
|
An example of an In Vivo function study,
VitB12 labeled with cobalt is administered. If the VitB is absorbed, it will be detected in excreted urine. If B12 is not absorbed, it will be in the feces. |
