One of the new probes, [18F]JK-PSMA-15, showed promising results in the preclinical in vivo μPET studies and could be suitable for high-qualityvisualization of small PSMA-positive lesions, although further studiesin appropriate tumor models may be required to corroborate these findings.Additionally, amine-reactive [18F]AFAs demonstrated a remarkablepreference for acylation of the sterically more accessible amino group,which could be exploited for the regioselective radiolabeling of peptidesand proteins. Here, FOLH1 is linked to neoplasm.
