FOLH1 and posterior cortical atrophy: In a group of 64 PCa patients with BR, 13 patients were judged positive for LR in both early dynamic images and images 60 min p.i. Furthermore, in six patients judged negative or equivocal in images 60 min p.i., early dynamic images revealed PSMA-positive findings suspicious of LR, increasing the DR of LR from 20.3% to 29.7%, while not reaching statistical significance.
