MRI and PET Scanning problem 10


Positron emission tomography (PET scanning) involves the detection of gamma radiation in order to identify the position of origin of positrons in the body.


  • Positrons are not naturally present in the body. Explain how positrons come to be present in the body during PET scanning.


  • Explain how positrons cause the emission of gamma-radiation from the body during PET scanning.
