Imaging in inflammatory disorders and infections

Question 1

What is the properties of the ideal isotope

Answer 1

Similar half life to length of procedure
Gamma emitter
Easily bound to pharmaceutical component
Energy of gamma rays should be 50-300 keV

Question 2

What happens in a tomography gamma camera

Answer 2

Nuclear energy, gamma rays being emitted from patient is picked up and image crystal produces flash of light and electrical energy converts it into a picture
