Ga-68-FAPI-04 PET/CT showed higher accumulation of radiotracer in primary tumor and axillary lymph nodes than F-18-FDG PET/CT. In addition, focal increased FAPI uptake was observed in another nodular lesion in the lower inner quadrant in the same breast, which was considered malignant. However, Tru-Cut biopsy of this lesion was reported as benign lymphoid tissue. This case showed that all FAPI accumulation in breast tissue should not be interpreted in favor of malignancy; histopathological confirmation is required.eninfo:eu-repo/semantics/closedAccessF-18-FdgGa-68-FapiBreast CancerPet/CtEditorial468E433E435WOS:0006696185000082-s2.0-851106228253378229510.1097/RLU.0000000000003594Q3Q1
