Moreover, Figs. 2a, b also reveal that for cell deposits with more than 1 × 106 cells, the sensitivity of Ga68-PSMA-11-PET in identifying small PCa cellular deposits is, against general perception, not coupled to the size of the lesion (or the nodal metastasis) [25] but rather to the density of PSMA-expressing cells mixed in the deposit. The gene discussed is FOLH1; the disease is posterior cortical atrophy.
