>> What are the 3 differences in MDP and F18 bone scan?
Answer: MDP emits gamma, F18 emits positrons, MDP uses a gamma
camera, F18 uses a PET/CT, F18 has a shorter t1/2, MDP has a longer

secondary bronchi, alveolar duct, alveolar sac, alveoli
>> What is the procedure of a R to L shunt exam in nuc med and why is it done?
Answer: Perfusion of MAA if there is a R to L then you would have uptake
in other organs such as liver, brain, kidneys due to it bypassing the lungs
due to R to L shunt
