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…
Spleen on FDG PET/CT
Abstract FDG-avid splenic lesions may be malignant (lymphoma most commonly) or benign, such as infections and sarcoid. Benign causes of splenic FDG avidity are common and must be distinguished from…
Introduction to FDG PET/CT
Abstract FDG PET/CT is a hybrid functional and anatomical imaging method with substantial application in oncology. This chapter introduces FDG PET/CT and how the functional and anatomic components combine into…
Lung on FDG PET/CT
Abstract The lung is an organ where integration of data from FDG PET, the CT, and the clinical history is particularly important. There are many FDG-avid lung lesions which will…
