Abstract The gastrointestinal tract poses challenges for interpretation on FDG PET/CT, as esophagus, stomach, small and large bowel may all demonstrate physiologic FDG avidity, and physiologic FDG avidity may be…
Abstract The female pelvis can be difficult to evaluate on FDG PET/CT. The endometrium and ovaries may demonstrate physiologic FDG avidity. Benign leiomyomata of the myometrium may be FDG avid….
Abstract The future of PET lies in the potential for multiple clinically valuable radiotracers other than FDG. This chapter discusses the basics of five additional clinically valuable PET radiotracers: 18F-sodium…
Abstract The urinary tract is one the most difficult organ systems of the body to evaluate on FDG PET/CT. This is because of physiologic excretion of FDG through the kidneys,…
Abstract FDG PET/CT has become an important modality in the evaluation of lymph nodes in oncology patients, including the central role FDG PET/CT plays in managing patients with lymphoma and…
Abstract The testes may demonstrate physiologic FDG avidity. Uncertain imaging findings in the testis on FDG PET/CT can be further evaluated with testicular ultrasound. FDG-avid foci within the prostate may…
Abstract The differential of peritoneal lesions includes both malignant (metastases, lymphoma, primary peritoneal malignancies) and benign (bowel perforations, pelvic inflammatory disease) etiologies. Peritoneal carcinomatosis may be visible on both FDG…
