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…
Heart on FDG PET/CT
Abstract For oncologic FDG PET/CT scans, the patient is in the fasted state and the myocardium has variable utilization of glucose versus other sources of energy for metabolism. This results…
Muscle and Nerve on FDG PET/CT
Abstract Muscles and nerves may demonstrate benign physiologic FDG avidity and must be distinguished from malignancy. This chapter describes common appearances of benign FDG avidity in muscles and nerves and…
Thymus Masses on FDG PET/CT
Abstract FDG avidity in the thymus is often benign thymic rebound. The characteristic triangular shape of benign thymus will distinguish it from malignancy. Thymic malignancies are uncommon, but include thymic…
FDG PET/CT Performance and Reporting
Abstract Optimal FDG PET/CT relies upon proper performance of the examination and reporting of the results. This chapter discusses proper patient preparation for FDG PET/CT, quantification of FDG uptake, and…
Pleura on FDG PET/CT
Abstract FDG avidity in the pleura may be malignant, such as metastases and mesothelioma, or benign, such as postpleurodesis inflammation. Corresponding CT findings, such as high attenuation from prior talc…
Brain on FDG PET/CT
Abstract The brain demonstrates substantial physiologic FDG avidity. Malignancy involving the brain, including metastases, lymphoma, and primary gliomas, may be detected either as foci of FDG avidity greater than physiologic…
Skin and Breast on FDG PET/CT
Abstract The skin and subcutaneous tissues are common sites of inflammatory lesions which must be distinguished from malignancy. Visual inspection of FDG-avid skin lesions is often needed to make this…
