Question
In a material medium, when a positron meets an the electrons both particles annihilateleading to the emission of two gamma ray photons. this process forms the basis of animportant diagnostic procedure called
Options
A.MRI
B.PET
C.CAT
D.SPECT
Solution
Position emission tomography (PET) is a nuclear medicine medical imaging techniquewhich produces a three dimensional image are map of functional process in the body. The positron annihilates with an electron producing a pair of annihiation photons (gama rays) moving in opposite direction.
