Abstract

We compared 68 Ga-Trivehexin PET/CT imaging with 18 F-FDG in a 49-year-old woman diagnosed with breast cancer. While both imaging modalities detected a soft tissue mass in the central left breast, 68 Ga-Trivehexin PET/CT identified not only the large lesion but also 3 additional tiny foci that were undetected by 18 F-FDG PET/CT. Our report suggested that 68 Ga-Trivehexin PET/CT might offer superior detection efficacy for breast cancer compared with 18 F-FDG PET/CT, highlighting its potential as an alternative imaging agent.
