FOLH1 and pachyonychia congenita: Rahbar K performed 18F-PSMA imaging on 100 PC patients who were suspected of biochemical recurrence and found that the cumulative detection rates for PSA levels ≤0.5, 0.51 to 1.0, 1.1 to 2.0, and >2.0 ng/mL were 86%, 89%, 100%, and 100%, respectively.[5] Another meta-analysis performed on different studies involving 645 patients showed the cumulative detection rate of 18F-PSMA PET/CT in biochemical recurrent PC was 81% with a 95% confidence interval (CI) of 71% to 88%.
