Amino acids such as [11C-methyl] l-methionine are particularly useful in brain tumor
diagnosis, but unspecific uptake (eg, in cerebral ischemia) has been reported. O-(2-[18F] …

Radiolabeled amino acids are useful for brain tumor diagnosis, but unspecific uptake near
the cerebral hematoma may complicate the differentiation of a neoplastic from a …

In patients with cerebral tumors, high accumulations of l-methyl-11 C-methionine (11 C-Met)
have been reported in some cases of cerebral ischemic disease, but no high accumulations …

1165 Objectives: The amino acid O-(2-[18F] fluorethyl)-L-tyrosine (FET) has been shown to
be a powerful tracer for brain tumor imaging. Experimental studies have shown that there is …

The amino acid O-(2-18F-fluoroethyl)-l-tyrosine (18F-FET) has been shown to be a useful
tracer for brain tumor imaging. Experimental studies demonstrated no uptake of 18F-FET in …

13 Objectives To measure K i (%/min) from Patlak-Rutland graphical analysis in normal
brain from grey matter (GM) and white matter (WM) to enable uptake in tumour regions to be …

Assessment of residual tumor after resection of cerebral gliomas can be difficult with MRI
and may be improved by amino acid PET. The aim of this experimental study was to …

O-(2-[18 F] Fluoroethyl)-l-tyrosine (FET) is a recently described amino acid analogue that
has shown high accumulation in animal tumours. The aim of this study was to compare the …

The use of amino acid PET tracers like F-18 fluorethyltyrosine (FET) in the diagnostic workup
of brain tumors has gained widespread acceptance. We report a case of a man who initially …
