Recovery coefficients (RC) used for applying PVE correction to the tracer uptake of each lesion. The symbols represent the measured RC for each NEMA NU-2 image quality phantom sphere. The final recovery coefficients used for PVE correction (lines) are obtained by applying a correction for the cold walls of the phantom spheres obtained by using a RC model [42] to compute the recovery coefficient ratio for spheres with and without walls
