The pleura are the pair of membranous linings surrounding the lungs. The visceral pleura covers each lung surface, and the parietal pleura covers the inner surface of the thoracic cavity. Normally, the visceral and parietal pleura oppose each other, have…

The lung is an organ where the integration of findings on 18F-fluorodeoxyglucose positron emission tomography (FDG PET), findings on computed tomography (CT), and the clinical scenario is particularly important to arrive at the best conclusions. Many FDG-avid lung lesions will…

Head and Neck Anatomy The head and neck has complex anatomy. Proper identification of benign and malignant lesions depends on an understanding of this anatomy and how it may be altered by surgery, chemotherapy, and radiation. The suprahyoid neck is…

Normal Brain 18F-Fluorodeoxyglucose (FDG) was initially designed to be a brain metabolism tracer and today has multiple applications in neurologic disorders, such as dementias and seizures. The demonstration of the value of FDG in metabolically active tumors has led to…

When approaching interpretation of osseous lesions on 18F-fluorodeoxyglucose positron emission topography/computed tomography (FDG PET/CT), it may be useful to use a 2 × 2 box divided into quadrants based on presence or absence of FDG avidity and malignant versus benign…

Performing FDG PET/CT Patients need to be prepared for 18F-flourodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in order to optimize the distribution of FDG in the body. Patients should avoid exercise starting the day before the examination in order to…
