Figure 4b:

Images in a patient who had undergone radical prostatectomy (PSA level, 1.1 ng/mL). (a) Transverse PET and (b) fused PET/CT scans obtained with anti-3-¹⁸F-FACBC. (c) SPECT and (d) fused SPECT/CT scans obtained with ¹¹¹In–capromab pendetide. Intense uptake on images obtained with anti-3-¹⁸F-FACBC (arrow in a and b) corresponded to a 5-mm recurrence in the left obturator lymph node, which was proved at biopsy. There is no uptake in same region on images obtained with ¹¹¹In–capromab pendetide (arrow in c and d). This is an example of a true-positive finding with anti-3-¹⁸F-FACBC and a false-negative finding with ¹¹¹In–capromab pendetide.
