FOLH1 and neoplasm: Even though only low activity levels were found in the blood pool for all ligands, [177Lu]Lu-rhPSMA-10.1 showed the best clearance of all investigated PSMA ligands, and this superior clearance is also expressed by the highest tumor-to-blood ratio (11,498): 3 times higher than for [177Lu]Lu-rhPSMA-7.3 and 8 times higher than for [177Lu]Lu-PSMA-617.
