FDG PET imaging is useful for preoperative diagnosis of pancreatic carcinoma in patients with suspected pancreatic cancer in whom CT fails to identify a discrete tumor mass or in whom FNAs are nondiagnostic. FDG PET imaging is useful for M staging and restaging by detecting CT occult metastatic disease, allowing noncurative resection to be avoided in this group of patients. FDG PET can differentiate post-therapy changes from recurrence and holds promise for monitoring neoadjuvant chemoradiation therapy. The technique is less useful in periampullary carcinoma and marginally helpful in staging except for M staging. As with other malignancies, FDG PET is complementary to morphologic imaging with CT, therefore, integrated PET/CT imaging provides optimal images for interpretation and thus more optimal patient care.
