Patient examples of SPECT/CT and PET/CT RECIP 1.0. (A) SPECT and PET maximum-intensity projection (MIP) images in 74-year-old man with mCRPC. Serum PSA level at baseline was 449 ng/mL and slightly increased to 525 ng/mL after two cycles of Lu-177 PSMA. Eastern Cooperative Oncology Group (ECOG) score was 2 at baseline and increased to 3 after 2 cycles. The patient was classified by readers as RECIP-progressive disease on both SPECT and PET. Overall survival was 4.7 months. Two cycles of Lu-177 PSMA were administered. (B) SPECT and PET MIP images in 74-year-old man with mCRPC. Serum PSA level was 231 ng/mL at baseline and decreased to 12.5 ng/mL after 2 cycles of Lu-177 PSMA. ECOG score was less than 2 at baseline and after 2 cycles of Lu-177 PSMA. The patient was classified by readers as RECIP-partial response on both SPECT and PET. Overall survival was 14.3 months. Four cycles of Lu-177 PSMA were administered.

Brain MRI and F-18 FDG brain and whole-body PET/CT images. (A) No obvious abnormalities were found in axial and sagittal slices from T2-weighted MR images. (B) Whole cerebellar cortex had diffuse F-18 FDG hypermetabolism in PET/CT brain images, with SUVmax of 25.91. (C and D) Whole-body F-18 FDG-PET/CT showing distended bladder. TLG = total lesion glycolysis; MTV = metabolic tumor volume. Image and caption courtesy of the Journal of Nuclear Medicine.
