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.

PCCT has higher safety profile than EID-CT for lung imaging

Subgroup analysis based on lesion size on PCCT images. The red outlined areas highlight the magnified images of lesions. (A-C) PCCT images in a 62-year-old woman with a body mass index (BMI) of 23.6, calculated as weight in kilograms divided by height in meters squared, who was diagnosed with adenocarcinoma. A lesion with a long diameter of 25 mm was identified in the right lower lobe on axial images acquired during the venous phase. For lesions less than or equal to 30 mm, decreasing section thickness improved boundary sharpness and contrast between the necrotic area and enhanced tissue, with optimal visualization at 0.4 mm. (D-F) PCCT images in a 66-year-old man with a BMI of 24.2 who was diagnosed with adenocarcinoma, revealing a lesion with a long diameter of 52 mm in the right lower lobe. For lesions greater than 30 mm, a section thickness of 1 mm demonstrated better contrast and clarity at the boundary of the necrotic area compared with 0.4 mm. This observation supported the selection of an appropriate section thickness for accurate quantification of necrotic regions within the lesion.
