WebFeb 23, 2024 · FDG-PET is affected by several limitations as well, mainly related to high physiological uptake in healthy tissue, such as salivary glands, brain, and oral cavity, and inflammatory uptake in cervical muscles or lymph nodes. Moreover, the presence of FDG-avid brown adipose tissue may impair image reading in FDG-PET scans. WebThe introduction of PET/computed tomography revolutionized PET imaging, bringing much-needed anatomical information. This modality allowed better characterization of some types of uptake, particularly brown adipose tissue FDG uptake. Different approaches to minimize interference from altered FDG biodistribution should be considered when ...
