Fig. 2
MIP of [68Ga]-Ga-PSMA-11 PET (A) with marginally positive (SUVmax 7.7) oligofocal local recurrence after seed implantation in both the right and left dorsoapical prostate lobe (green arrow). The accumulation was retrievable in both the attenuation corrected fused axial slices (B) and in the non-attenuation corrected axial slices (C). In [18F]-F-PSMA-1007 PET neither in the MIP (D) nor in the attenuation corrected fused axial slices (E) nor in the non-attenuation corrected axial slices (F) focal uptake was noted. Immunhistochemical images (G, H) show several, diffuse, small tumor cell nests with moderate to intense PSMA-expression
