Some recent studies using specific radiotracers without glucose, as 11C-choline, 18F-fluciclovine, prostate-specific membrane antigen (PSMA) and 18F-sodium fluoride, had promising results, distinguishing areas of prostatic cancer from normal tissue, as well as evaluating bone metastasis [34,40,41]. Here, FOLH1 is linked to Familial prostate cancer.
