Robustness of recovery curves. Recovery concentration coefficient versus lesion-to-background ratio for 10-mm lesion measured in Probe-IQ pelvis. (Top to bottom) Max, Peak, Apex, and Mean (40% FT and gradient). (Left to right) Reconstruction algorithms using OSEM + PSF (24 and 32 subsets, respectively) and BSREM. Range and standard deviation of recovery coefficients annotated on plots. [¹⁸F]DCFPyL background activity levels are represented by red shaded region
