FOLH1 and posterior cortical atrophy: The first study performing a comparative evaluation between these two radiotracers in recurrent PCa is the one by Minamimoto et al. In this pioneering work, comparing the biodistribution of 68Ga-PSMA-11 and 68Ga-RM2 in a small cohort of patients with biochemically recurrent PCa, PET/CT was adopted for 68Ga-PSMA studies while PET/MRI scanner was used for 68Ga-DOTA-RM2 PET acquisitions [18].
