Purpose Several factors have been identified that predict positive fluorine-18-fluoromethylcholine (F-18-FCH) PET/CT result in patients with prostate cancer undergoing PET/CT for biochemical failure. Among these factors, prostate-specific antigen (PSA) is the single factor most consistently associated with the prediction of positive F-18-FCH PET/CT. In this study, we wished to confirm this finding and expand it in a large series of patients. Patients and methods We retrospectively analyzed 192 patients with prostate cancer who were recruited from the Nuclear Medicine Department of the Sant'Andrea Hospital of La Spezia, Italy, from March 2013 to March 2018 and who underwent F-18-FCH PET/CT owing to biochemical failure after radical prostatectomy. Results Median trigger PSA was 2.57 ng/ml. The overall positive detection rate of F-18-FCH PET/CT was 60.9%. The percent of positive scans was 30.5% for PSA less than 1 ng/ml, 59.4% (38/64) for PSA between 1 and 5 ng/ml, and 88.4% for PSA greater than 5 ng/ml (P
