Representative case of response. 86 y/o M with metastatic castration-resistant prostate cancer, Gleason score 4+4, baseline PSA 63.43 ng/ml, which decreased to 10.01 ng/ml after 6 cycles of chemotherapy. A. Axial image of fluciclovine PET with abnormal uptake in the right proximal femur. B. Axial image of fused fluciclovine PET/CT with abnormal uptake in the right proximal femur. C. Coronal image of fluciclovine PET. D. Coronal image of fused fluciclovine PET/CT. Images demonstrate decreased intensity of fluciclovine uptake in the same lesion on subsequent imaging after chemotherapy.
