What is the utility of FDG PET in nonneoplastic vascular disease? Heart disease (the most common cause of death in the U.S.) and cerebrovascular disease in large part are due to atherosclerosis, a chronic inflammatory disorder of the arterial tree. FDG PET is useful to detect and quantify the inflammatory component of atherosclerosis during the …

What is the role of FDG PET MRI in the nononcological setting? FDG PET/MRI is most promising for the evaluation of patients with nononcological disorders that involve anatomic sites that are suboptimally evaluated at CT. In particular, PET/MRI may be particularly useful for evaluation of patients with neurologic, cardiovascular, and musculoskeletal nonneoplastic disorders. Available functional …

What is the utility of FDG PET for disease restaging of cancer patients? FDG PET has high diagnostic accuracy for the early detection of recurrent tumor, even when no other symptoms or signs of tumor recurrence are present, leading to improved clinical outcomes. Moreover, it allows for precise spatial localization of the sites of tumor …

What is the utility of FDG PET for response assessment in cancer patients? FDG PET is useful for accurate early quantitative assessment of tumor response to therapy and provides the opportunity to change treatment promptly in the case of a nonresponse, thereby ameliorating or preventing unnecessary side effects while maximizing the chance for an improved …

How useful is FDG PET for the evaluation of primary and metastatic brain tumors? FDG PET generally has low sensitivity for early detection of primary or metastatic brain tumors, given the normal high level of FDG uptake in the brain. For this reason, MRI is predominantly utilized for diagnostic assessment of the brain in cancer …
