Gastrointestinal Tract on FDG PET/CT
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…
Female Pelvis on FDG PET/CT
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….
Radiotracers Other Than FDG for Oncologic PET/CT
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…
Urinary Tract on FDG PET/CT (Kidneys, Ureters, Bladder)
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,…
Lymph Nodes on FDG PET/CT
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…
Male Pelvis on FDG PET/CT
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…
Peritoneum on FDG PET/CT
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…
Skeleton on FDG PET/CT
Abstract This chapter describes FDG PET/CT interpretation of the skeletal system. FDG-avid osseous malignancy includes metastases, lymphoma, multiple myeloma, and sarcomas. Some osseous malignancy may not be FDG avid, such…
Pancreas on FDG PET/CT
Abstract Focal FDG avidity within the pancreas is suspicious for a focal pancreatic malignancy. However, there are many inflammatory causes of FDG avidity such as pancreatitis (such as secondary to…
Artifacts on FDG PET/CT
Abstract All imaging modalities may be compromised by artifacts that obscure malignancy or mimic malignancy. FDG PET/CT may be compromised by a multitude of artifacts, primarily associated with technical performance…
