To date, a clinical pilot investigation with this 68Ga-labeled PSMA derivative (Glu-NH-CO-NH-Lys-(Ahx)-(68Ga)Ga(HBED-CC)) further denoted as 68Ga-DKFZ-PSMA-11) suggested that it detects PC relapses and metastases with higher contrast as compared to 18F-labeled choline [20]. Here, FOLH1 is linked to pachyonychia congenita.
