FOLH1 and posterior cortical atrophy: For example, a study in 96 patients with PCa demonstrated that 18F-PSMA-1007 PET had a sensitivity of 85.9% and a specificity of 99.5% in a patient-based analysis for detecting positive lymph nodes larger than 3 mm.309 Furthermore, the 99mTc-labeled PSMA ligand 99mTc-MIP-1404 is in a phase 3 clinical trial designed to evaluate its sensitivity and specificity to detect PCa (Table 4).
