Nuclear medicine imaging is fundamentally statistical. Photon detection follows Poisson distribution, and image noise depends directly on count rate.

This section covers count statistics, standard deviation, signal-to-noise ratio, and the relationship between counts and image quality. It also explores dead time, detector efficiency, and factors influencing count loss.

Statistical principles are heavily examined in radiology physics assessments, particularly in questions linking acquisition parameters to noise and resolution.

The questions in this section strengthen quantitative reasoning and interpretation of statistical effects in radionuclide imaging.
