Which outcome occurs when a PET scanner's germanium-68 source decays?

A)Background radiation count increases significantly
B)Image resolution improves noticeably
C)Patient dose decreases proportionally
D)Scan duration shortens substantially

💡 Explanation

Gamma photons result along with new isotopes. Therefore, elevated counts of background radiation impact all subsequent scans undertaken, because the **Compton scattering** increases; rather than resolution increases when using increased radiation, patient radiation doesn't decrease.
