433 Objectives PET imaging of brain tumors with amino acid-based radiotracers provides
the advantage of a low background activity in the cortex and white matter not affected by the …

487 Objectives 1. To evaluate the potential utility of PET/CT imaging using C-11 methionine
(MET) as a tracer of the large neutral amino acid transport system in children and young …

The fact that some brain tumors show hypo-or isometabolism on fluorine-18
fluorodeoxyglucose positron emission tomography (FDG PET) has caused problems in the …

Background Static imaging of amino acids does not allow differentiation of low versus high
grade brain tumours. It has been shown that dynamic imaging of the amino acid analogue …

1827 Objectives 11 C-methionine (MET) positron emission tomography (PET) imaging is a
sensitive technique for visualizing primary and recurrent brain tumors. Acquisition in 20 …

BACKGROUND AND PURPOSE:[11C] Methionine (MET) PET imaging is a sensitive
technique for visualizing primary brain tumors and recurrence/progression after therapy. The …

Abstract 11 C-methionine (MET) is the most popular amino acid tracer used in PET imaging
of brain tumours. Because of its characteristics, MET PET provides a high detection rate of …

1340 Objectives 18F-fluoro-boronophenylalanine (FBPA) is one of amino acid derivatives
and has been used to select patients and to evaluate boron levels in the tumor for boron …

11C-Methionine PET is a well-established technique for evaluating tumor extent for
diagnosis and treatment planning in neurooncology. Image interpretation is typically …

Abstract Background [11C]-Methionine PET ([11C]-MET-PET) is principally used for the
evaluation of brain tumors in adults. Although amino acid PET tracers are more commonly …
