Pre-chemotherapy staging PET scan shows a locally advanced gastric cancer.PET from skull to mid-thigh reveals extensive, diffuse hypermetabolism throughout the gastric wall compatible with a PET-avid infiltrating gastric neoplasm. Imaging revealed involvement of at least one hepatogastric lymph node. Thus, the patient was determined to have stage III disease (T3N1). Scattered areas of contrast uptake within the bowel are likely physiologic and limit evaluation for lesions. Contrast uptake within the brain and genitourinary system are physiologic.
