18-FDG-PET scanning is an important imaging modality in the staging and monitoring of many malignancies, including lymphoma. Some tumors, however, do not have the high glucose uptake needed for 18-FDG uptake, and are therefore not well imaged by PET. In order to assess whether the histologic subtype of a lymphoma is related to its visibility by PET imaging, this retrospective analysis of PET scans was performed at the University of Pennsylvania. The author's assessed PET positivity of newly diagnosed and untreated relapsed lymphoma by WHO classification of the tumors.
Materials and Methods
Of >600 PET scans performed on patients with lymphoma, 155 cases had
pathologic data available for correlation.
Sep 19, 2014 - The five-point Deauville scale, used to score 18F-fluorodeoxyglucose (FDG) uptake on FDG positron emission tomography-computed tomography scans, has prognostic value in follicular lymphoma, according to a study published online Sept. 18 in The Lancet Haematology.
