Nuclear Imaging Flashcards
nuclear imaging is what
nuclear medicine though indicates intent of dx
general indication
testing of function of tissues
dx by what
physiologic change as opposed to structure
mechanism
- radionuclide emits gamma rays introduced
- absorbed differently by tissues based on metabolic activity
- gamma rays observed by special camera
- computer converts to digital image
static method
single image of targeted body region
whole body method
AP - bone scans
dynamic imaging
timed sequence - cardiac, hepatobiliary, gastric
single photon emission computed tomography (SPECT)
3D - bone, cardiac perfusion, brain, liver
positron emission tomography (PET)
biologic function of cells - CNS studies, tumors
indications
cancer
detection of metabolic bone diseases and other osteopathies
detection of other bone abnormality

nuclear image of a skeleton
what do hot spots on an image indicate
black spots
increased uptake
increased uptake
