A high GS at diagnosis is a strong predictive factor for positive (18)F-choline PET/CT scan results for recurrent PCa, even when the PSA level is low (i.e., ≤1 ng/mL).
Taking the TBR into consideration, 99m-STS proved a very useful tool for distinguishing AIT-1 from AIT-2, and thus offering patients appropriate treatment as of their diagnosis. This approach can avoid pointless and potentially dangerous combined overtreatments, and may speed up the return to normal thyroid function, which is crucial in AIT patients suffering from heart disease.
InTroDucTIon 18 F-FDG PET/CT (18 F-fludeoxyglucose PET/CT) has become a standard procedure in many types of neoplasms in children. 1-11 The combination of anatomical and metabolic imaging modalities provides accurate diagnostic information useful in initial staging, therapy monitoring, and follow-up of different pediatric diseases. Nevertheless, the introduction of integrated PET/MR scanners in clinical practice has raised interest in its use and benefit in pediatric patients. Published studies have confirmed its non-inferiority to PET/CT in many oncological applications. 12-15 The main reasons in support of PET/MR use in children are the potential of MRI to complement PET metabolic information and the significant reduction in radiation exposure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
