- W2967140949 abstract "1924 Objectives To explore the value of 18F-FDG PET/CT in distinguishing high and low grade pediatric brain tumor. Methods 18F-FDG PET/CT were performed in 19 patients with brain tumor before surgery (10 males,9 females,mean age 2.13y).All the cases were confirmed by pathological results.PET/CT images were analysed by visual observation and semiquantitative methods.The patients were divided into 2 groups as high and low grade.T-test was used to evaluated the statistical differences between 2 groups.The area under ROC curves and optimal diagnostic cut-off (ODC) were used for this study. Results There were 8 in low grade group(grade I and II each was 4) and 11 in the other group(grade III was 4 and grade IV was 7).a the maximum FDG uptake(SUVmax) was significantly different between 2 groups(t=-2.394,p=0.028 Conclusions 18F-FDG PET/CT may be useful for distinguishing high and low grade pediatric brain tumor.Among all the semiquantitative methods,SUVmax and T/W had highest diagnostic value.SUVmax was siginificantly correlated with pathological results." @default.
