The sensitivity and specificity of [68 Ga]Ga-PSMA-11 PET/MRI vs. mpMRI in the detection of PCa on a segment basis were 76% vs. 43% (p = 0.001) and 97% vs. 98% (p = not presented), respectively, clearly favouring the detection of PCa by [68 Ga]Ga-PSMA-11 PET/MRI. The gene discussed is FOLH1; the disease is posterior cortical atrophy.
