18F-Fluciclovine PET/MRI in a patient with squamous cell carcinoma of the uterine cervix correlated with 18F-FDG PET/CT

Abstract

A 32-year-old woman with a FIGO (International Federation of Gynecology and Obstetrics) stage IIA invasive squamous cell carcinoma of the uterine cervix underwent a clinical FDG PET/CT scan, which revealed intense uptake in the primary. On research 18F-fluciclovine PET/MRI, the primary showed elevated fluciclovine uptake at 5 and 40 minutes after radiotracer injection, with no evidence of regional or distant metastasis. Fluciclovine PET may have diagnostic value for cervical cancer imaging with a potential advantage over FDG of minimal urinary activity from renal excretion; however, in this patient, the metabolic activity was inferior to that of FDG PET.
