Final Recap
Nuclear Imaging
track a path of a radioactive tracer
Single Photon Emission Computed Tomography
Positron Emission Tomography
SPECT
PET
different types of radiotracers
allow to identify normal and abnormal activity in living tissue
SPECT and PET
functional chemical changes
typically metabolic activities
both use radioactive tracers
carrier
radioactive atom
carrier binds to protein or sugar in the body
for example to detect a tumor
very similiar
SPECT: Gamma Rays
PET: Positron Imaging
both have low resolution!
Voxel size for CT: 0.625-1.25 mm^3
similar to MRI
0.1-1 mm^3
SPECT/PET 5-10mm^3
even lower
usually combined with CT scan
