Q
What body part/tissue gives the best spatial resolution in PET imaging?
A
Bone
spatial resolution in PET is based on time of flight and how far a positron travels in the density of the material before electron-positron annihilation
in materials of higher density, such as bone positrons are more likely to find and interact with an electron at a closer distance to their origin than in material of lower density.
lung would have the worst spatial resolution
