New theranostics PET tracer shows promise
A new gallium-68 (Ga-68) PET/CT radiotracer appears superior over F-18 FDG for detecting bone metastases.
April 17, 2025
Images of a 69-year-old man diagnosed with prostate cancer who had a history of endocrine therapy for two years. (a) The maximum intensity projection (MIP) image of F-18 FDG showed moderate radiotracer uptake in a thoracic vertebra. (e) The MIP image of Ga-68 DOTA-IBA demonstrated more lesions in the cervical vertebra and pelvis. (b) An osteoblastic lesion in the C3 vertebra right attachment (curved arrows) was negative on F-18 FDG (SUVmax = 2.0) and positive on Ga-68 DOTA-IBA (SUVmax = 8.7). (c) Another osteoblastic lesion in the T10 vertebra left side (arrowheads) was both positive on F-18 FDG (SUVmax = 5.2) and positive on Ga-68 DOTA-IBA (SUVmax = 35.0). (d) Osteoblastic lesions in bilateral ilium (dotted arrows and arrows) were negative on F-18 FDG (left: SUVmax = 1.4, right: SUVmax = 1.6) and positive on Ga-68 DOTA-IBA (left: SUVmax = 7.6, right: SUVmax = 8.7). Follow-up imaging three months later confirmed the presence of these bone metastases.

Mammo uptake among veterans on par with nonveterans
Female veterans are as likely to undergo screening mammography as nonveteran women.
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.
