Types of Radiology Flashcards
Nuclear Imaging types tracer do what
dx therapy, and research
nuclear imaging tracer types
pharmaceutical - target organs
radionuclide - gamma ray emission - metabolic activity
general indication for nuclear imaging
dx by physiologic change as opposed to structure
static nuclear imaging
single image of targeted body region
whole body nuclear imaging
AP - bone scans for example
dynamic nuclear imaging
timed sequence - cardiac, hepat, gastric
SPECT nuclear imaging
3D - bone, cardiac, brain, liver
PET nuclear imaging
function of cells
Clinical indication of nuclear imaging
CA - staging
bone
MSK
black spots on nuclear imaging
hot spots - indicate lot of uptake
nuclear imaging bone scan
high sensitivity for changes but low specificity on what specifically it is
CT what is it
takes up to 1000 x rays all around to get a 2D image where you can see all sides like a box
indications for CT
limitations
bone/soft tissue tumor
fx
inability to distinguish small areas of diff tissue
CT variants
3D
CT myelogram
3D - multiplanar reconstruction
CT myelogram - adding contrast materials to allow for increased visualization of structures impinging on nuero stuff
increased radiodensity =
more white
