Which outcome occurs when a PET scanner's positron emission fails?

💡 Explanation

Increased background noise arises because the annihilation photons linked via electron-positron annihilation are absent, so statistically less specific radiation dominates and degrades the image rather than signal accuracy due to altered decay rates.
