Although several [99mTc][Tc]-tagged PSMA inhibitors have been developed and evaluated in preclinical studies for PCa detection, results from these investigations have disclosed that most of these agents possess some drawbacks concerning radiosyntheses and full chemical characterizations (unclear structures) of the radioconstructs, as well as the lack of uniformity in the expression of receptor affinity data that make a straight comparison between the different [99mTc][Tc]-PSMA-i difficult. Here, FOLH1 is linked to posterior cortical atrophy.
