FOLH1 and posterior cortical atrophy: Consequently, preclinical and clinical studies of 99mTc-PSMA complexes have recently been performed to evaluate their potential as radiopharmaceuticals for PCa diagnosis using PSMA-derived inhibitors radiolabeled with [99mTc(CO)3]+ [8,9,10], 99mTc(V) Oxo Core [11,12], 99mTc-HYNIC [13,14,15,16,17] to produce a wide range of PSMA imaging agents [18].
