The assessment of cerebral gliomas using magnetic resonance imaging (MRI) provides excellent structural images but cannot solve all diagnostic problems satisfactorily. The differentiation of tumour tissue from non-neoplastic changes may be difficult especially in the post-treatment phase. In recent years, positron emission tomography (PET) using radiolabelled amino acids has gained considerable interest...
Objective We aimed to evaluate the diagnostic potential of dual-time-point imaging with positron emission tomography (PET) using O-(2-[18F]fluoroethyl)-L-tyrosine (18F-FET) for non-invasive grading of cerebral gliomas compared with a dynamic approach. Methods Thirty-six patients with histologically confirmed cerebral gliomas (21 primary, 15 recurrent; 24 high-grade, 12 low-grade) underwent dynamic...
