The Role of PET Scanning in Pancreatic Cancer
For many years computed tomography (CT) has been the principal imaging modality used for diagnosis and staging of patients with pancreatic cancer. Currently, contrast enhanced multidetector CT (ce MDCT), remains the most commonly used imaging study in the initial evaluation of these patients. Depending on clinical practices and preferences, other modalities, such as magnetic resonance imaging (MRI) and endoscopic ultrasonography (EUS), are also utilized in the diagnosis and staging of pancreatic carcinoma (1, 2).
The use of positron emission tomography (PET) in routine oncology practice has accelerated significantly in the past decade. Oncologic PET imaging is mainly performed with F18-FDG (FDG), a glucose analog that accumulates in cancer cells. This modality is under investigation in the evaluation of patients with pancreatic carcinoma as a diagnostic tool to better define extent of disease and guide treatment. Specifically, the ability of FDG-PET to find metastasis to the liver and elsewhere may be of great value in the management of patients with pancreatic cancer.
