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…
Hepatobiliary FDG PET/CT
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)…
Measuring Treatment Response on FDG PET/CT
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,…
Head and Neck on FDG PET/CT
Abstract The head and neck have complex anatomy and there are multiple causes of physiologic FD avidity in the head and neck. Proper evaluation of benign and malignant lesions depends…
Adrenal Glands on FDG PET/CT
Abstract FDG-avid adrenal lesions may be malignant (metastases, lymphoma, adrenal cortical carcinoma) or benign (such as adenomas). Most benign adrenal neoplasms demonstrate background FDG avidity; however, a small percentage of…
