From: Variability in lutetium-177 SPECT quantification between different state-of-the-art SPECT/CT systems
Comparison in range over all systems in RCmean (a) and RCmax (b) per sphere diameter for data reconstructed with a vendor-specific algorithm versus a vendor-neutral algorithm. Third and fourth columns give the same information but for systems of only one vendor, thus consisting of equal system hardware
