As an indicator of PSMA expression, the mean standardized uptake value (SUVmean) is a measurement parameter used in PET scans that quantifies the average concentration of radiotracer ligand uptake within the entire segmented tumor volume, whereas the maximum standardized uptake value (SUVmax) is the SUV of the single voxel with the highest concentration of radiotracer ligand in the entire segmented tumor volume (40). This evidence concerns the gene FOLH1 and neoplasm.
