FOLH1 and neoplasm: The average 1 h and 3 h SUVmax of 18F-PSMA-1007 in tumor tissue, parotid glands, liver, kidneys and spleen can be compared to data for PSMA-11 [9, 29] and PSMA-617 [30], because the evaluation of these 68Ga-labelled PSMA-ligands were also performed at our institution with similar imaging protocols, cross-calibrated scanners and analysis software.
