title: 18F-Fluorodeoxyglucose PET/CT in Langerhans cell histiocytosis: spectrum of manifestations.
abstract: The objective of this article is to provide an illustrative tutorial highlighting the utility of 18F-FDG PET/CT imaging to detect the spectrum of manifestations in patients with Langerhans cell histiocytosis. FDG PET/CT is a powerful tool for making an early diagnosis; it allows higher diagnostic confidence with regard to lesions, measuring the extent of disease (staging) and assessing disease activity, and is consequently useful for evaluating the response to therapy in patients with Langerhans cell histiocytosis.
