Detection Rate of ¹⁸F-Fluorethylcholine-PET/CT in relation to PSA Value in PCA Patients Referred with Biochemical Relapse

Figure 3

A 64-year-old PCA patient referred with PSA rising (11.5) after radical prostatectomy. The initial ¹⁸F-fluorethylcholine PET-CT demonstrated mildly increased uptake in a slightly enlarged perirectal lymph node. Six months later, the repeated ¹⁸F-fluorethylcholine PET-CT exhibited marked increase in both volume and intensity. This interval progression would verify the diagnosis of lymph node metastasis as a cause of PSA relapse.
