1682 Objectives: 18 F-Fluorodeoxyglucose (FDG) PET is used extensively for assessment of
the histological grading of gliomas. The 2016 WHO guideline emphasizes the importance of …

179 Objectives Amino acid PET with 11 C-methionine (MET) is well established in the
diagnostic work-up of malignant brain tumors. Analysis of MET-PET data using tumor-to …

1895 Objectives Texture indices (TI) and shape indices are of growing interest for tumor
characterization in FDG PET. To the best of our knowledge, such indices have never been …

1780 Objectives Delineation of volume of interest (VOI) for FDG PET of brain tumor is difficult
due to non-zero brain uptake in the surrounding tissues, making it difficult to use volume …

327 Objectives We studied whether the characterization of tumor texture in FDOPA PET/CT
could assist in the identification of tumor grades in both primitive and recurrent gliomas …

963 Objectives: The determination of tumor heterogeneity by new non-invasive tool as
textural analysis has recently gained attention. The aim of this study was to assess the …

326 Objectives Differential diagnosis of brain tumors between primary central nervous
system lymphoma (PCNSL) and glioblastoma multiforme (GBM) is critical since they need …

Objectives The determination of tumor heterogeneity by new non-invasive tool as textural
analysis has recently gained attention. The aim of this study was to assess the potential …

P123 Introduction: 39-deoxy-39-18 F-fluorothymidine (FLT) and 49-[methyl-11 C]-
thiothymidine (4DST) are useful in noninvasive evaluation of the proliferation. Tumor …

Texture indices are of growing interest for tumor characterization in 18F-FDG PET. Yet, on
the basis of results published in the literature so far, it is unclear which indices should be …
