Is FDG PET useful to evaluate muscle metabolism? Yes. FDG PET is useful to detect and quantify alterations in muscle metabolism due to a variety of disorders such as polymyositis, dermatomyositis, and COPD. In addition, FDG PET is useful to evaluate alterations in muscle metabolism that occur due to systemic therapies. At present, FDG PET …
Is FDG PET useful to evaluate brown fat? Yes. FDG uptake in brown fat is seen in about 5% to 10% of patients and is most often seen symmetrically in the supraclavicular, mediastinal, paravertebral, posterior intercostal, and retroperitoneal paraaortic and perinephric locations. A specific diagnosis is made when corresponding CT or MR images demonstrate fat …
What is the utility of FDG PET in inflammatory bowel disease (IBD)? CT, MRI, fluoroscopy, and endoscopy are commonly used to evaluate patients with IBD. However, detection and quantification of the active inflammatory components may be challenging, even though these tasks are important for treatment planning and response assessment purposes. FDG PET provides a means …

What is the utility of FDG PET in joint disease? FDG PET is useful to detect and quantify the extent and degree of inflammation in patients with joint disease, including arthritis, tendinitis, and synovitis, and is complementary with other structural imaging modalities such as radiography and MRI. On FDG PET, increased FDG is observed in …
What is the utility of FDG PET in psoriasis? FDG PET is useful to detect and quantify the spatial extent and inflammatory disease activity of psoriasis plaques in the skin, as well as to assess response to therapy. In addition, FDG PET is useful to detect and quantify unsuspected vascular and systemic sites of inflammation …
What is the utility of FDG PET in nonneoplastic thoracic disorders? FDG PET is useful to assess the spatial extent and inflammatory activity of disease, to aid in the identification of sites suitable for tissue sampling, and to monitor the effects of therapy in patients with nonneoplastic thoracic disorders such as sarcoidosis, interstitial lung disease …

What is the utility of FDG PET in suspected infection? FDG PET is useful to detect infections that are not detected by other methods, to determine the spatial extent and severity of infections, and to monitor the effects of therapeutic interventions. Bacterial, mycobacterial, viral, fungal, and parasitic infections typically reveal areas of increased FDG uptake, …
