A dedicated 3D brain scanner PET scanner has several advantages, most notably increased sensitivity, over a whole body scanner for neurological studies. This paper uses noise effective count-rate (NECR) analysis to compare brain scanners of 53, 60, and 66 cm diameter with the GE Advance whole body scanner (93 cm diameter). Results show that the brain scanners have noise effective sensitivities as much as 40% higher than Advance. However, their NECR advantages diminishes quickly as the activity concentration increases; the brain scanner' NECR equals Advance at approx.0.3 μCi/cc, and Advance has superior NECR performance at higher activity levels.
