title: The use of PET-18FDG imaging in the clinical evaluation of head and neck lymphoma.
abstract: Four patients with non-Hodgkin's lymphoma in the head and neck region were studied with positron emission tomography (PET), using the radioactive tracer 2-[F-18]-fluoro-2-deoxy-D-glucose (18FDG). This technique, which exploits the high metabolic rate of glucose in tumour tissue, enabled the extent of disease to be visualized. The localization of the tumour was improved by combining the data from the PET scan with those from CT scans or MRI. This technique (of PET-18FDG), using visual and semiquantitative analysis in the form of standardized uptake values, allowed the differentiation between reactive hyperplasia and nodal involvement with lymphoma. We believe that PET using the tracer 18FDG may play an important role in the evaluation of patients with head and neck lymphoma.
