FDG PET CT has limitations in breast cancer due to its low tracer uptake in Grade 1 and 2 tumors, estrogen receptor positivity, lobular histology, and osteoblastic skeletal metastases. Trivehexin PET targets αvβ6 integrin, which is relatively specific for epithelial cancer cells. We present a case of a 67-year-old woman with recently diagnosed metastatic breast cancer. Trivehexin PET not only showed lesions with a higher target-to-background ratio compared with FDG PET but also depicted additional metastatic sites.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
