title: Infrequent Tumors of the Gastrointestinal Tract Including Gastrointestinal Stromal Tumor (GIST).
abstract: The scientific basis of the use of FDG-PET in the diagnosis and management of patients with malignancies has been well established since the 1990s. This nuclear medicine imaging technique plays an essential role in the management of many cancers including lung cancer, breast cancer, lymphoma, melanoma, and various gastrointestinal malignancies, such as colorectal cancer and esophageal cancer. This article focuses on the use of FDG-PET in tumors of the gastrointestinal system that are less frequently encountered, such as gastrointestinal stromal tumor, gallbladder carcinoma, gastric lymphoma, and intrapapillary mucinous neoplasm of the pancreas.
