タイトル Simplified Quantitative Analysis of FDG Uptake Using the Brain
Introduction
Quantitative analysis of 18-fluoro-deoxyglucose (FDG) uptake is important in
oncologic positron emission tomography (PET) studies in order to determine
the malignancy of tumor. Currently, SUV (Standardized Uptake Value) is most
popularly used to evaluate the malignancy quantitatively. Although this
method is simple, it is often difficult to clarify the malignant and benign tissues
which SUV values were around the borderline. Several reasons were
considered for the diagnostic difficulty with SUV such as partial volume effect, the
way of image reconstruction or metabolic condition of the patient. Especially,
changes of blood glucose largely affected to the uptake of FDG in the tissue,
which is not accounted in SUV. Brain reference index (BRI) is a novel quantitative
method that is not affected by changes of blood glucose and is strongly correlated
to tissue glucose utilization. Thus, we compared BRI to SUV in the same patients,
and evaluate the usefulness of this method for the diagnosis of tissue
malignancy
