¹¹C-Acetate PET/CT and gallium 68 (⁶⁸Ga)–RM2 (bombesin analog) PET/CT of a 64-year-old man with newly diagnosed prostate cancer found at biopsy (Gleason score, 4 + 4 = 8; PSA level, 30 ng/mL), who was referred for cancer staging. (a, b) ¹¹C-Acetate PET/CT image (a) and ⁶⁸Ga-RM2 (bombesin analog) PET/CT image (b) show a suspicious lesion (arrow in a, b) in the right prostatic peripheral zone. Note the physiologic uptake of ¹¹C-acetate in the skeletal muscle on a. (c) Photograph of a macrosection obtained at robotic prostatectomy helps verify the presence of prostate cancer with invasion of the prostatic capsule (arrow).
