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…
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…
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…
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…
Abstract It is important to understand the differential diagnosis for solid and cystic liver lesions. Malignant solid liver lesions include metastases, lymphoma, and primary malignancies such as hepatocellular carcinoma (HCC)…
Abstract Currently, the most common method of measuring treatment response in malignancy use size measurements on CT and magnetic resonance (MR). However, metabolic changes in tumors, measurable by FDG PET/CT,…
