F-18 FDG PET/PET-CT in the Management of Lymphoma

Abstract

Positron emission tomography (PET) provides metabolic information and is superior to CT scan. The major utilization of PET is in oncology. Most commonly used PET tracer is fluorine 18 fluorodeoxyglucose (FDG), an analogue of glucose. This isotope accumulates in most tumours in a greater amount than it does in normal tissue. Malignant lymphomas are a heterogeneous group of diseases whose treatment and prognosis depend on accurate subtype and staging. F-FDG PET scan has been found useful in the staging and follow-up of Hodgkin’s and non-Hodgkin’s lymphoma. Here we review role of FDG PET in management of lymphoma.
