Retrospective Study Comparing WBC scan and F-FDG PET/CT in Patients with Suspected Prosthetic Vascular Graft Infection.

Objectives: Prosthetic vascular graft infections (PVGIs) are associated with high mortality rates. To improve treatment outcome, an early and definite diagnosis is critical, and current diagnostic criteria are often insufficient. The accuracy of 2-deoxy-2-[fluorine-18]-fluoro-d-glucose positron emission tomography integrated with computed tomography (F-FDG PET/CT) and white blood cell (WBC) scan for the diagnosis of PVGI were compared.

18F-DOPA PET/CT in Orbital Metastasis From Medullary Thyroid Carcinoma.

A 53-year-old-woman is being followed up for a sporadic medullary thyroid carcinoma that was initially treated surgically. Nine years later, a progressive increase in calcitonin levels along with headaches was observed. An orbital metastasis from medullary thyroid carcinoma was diagnosed by performing an F-DOPA PET/CT.
