The transport mechanisms of O-(2-[ 18 F]fluoroethyl)-L-tyrosine (FET) and 2-[ 18 F]fluoro-L-tyrosine
(FTyr) were compared to those of [ 3 H]-Methyl-L-methionine (MET) in F98 rat glioma …

[ 90 Y]DOTA-dPhe 1 -Tyr 3 -octreotide ([ 90 Y]-SMT487) has been suggested as a promising
radiotherapeutic agent for somatostatin receptor-expressing tumours. In order to quantify …

The amino acid analog 3-[123l] iodo-a-methyl-i_-tyrosine (IMT) is under clinical evaluation
as a SPECT tracer of amino acid transport in brain tumors. This study investigated the carrier …

The transport mechanisms of cis-4-[ 18 F]fluoro-L-proline (cis-FPro) and trans-4-[ 18 F]fluoro-L-proline
(trans-FPro) were studied in F98 rat glioma cells in comparison to the natural …

Tumor imaging with cis-4-[ 18 F]fluoro-L-proline (cis-FPro) was compared to that of L-[ 3 H]proline
and L-[ 3 H]methionine in F98 rat gliomas by dual-tracer autoradiography. All tracers …

3[ 123 I]iodo-α-methyl-L-tyrosine is a tracer of amino acid transport in brain tumors using
single-photon emission-computed tomography and predominantly transported by amino acid …

S-phase portionof 25% — 40%. For furtherexaminationof the cells, an enzymatic method for
detachment from the carriers without cellular destruction was introduced. In the FDG experi …

The amino acid analog 3-[123l] iodo-a-methyl-i_-tyrosine (IMT) is under clinical evaluation
as a SPECT tracer of amino acid transport in brain tumors. This study investigated the carrier …

Nicotinic acetylcholine receptor (nAChR) subtypes containing the α 4 subunit, particularly α
4 β 2 nAChRs, play an important role in cognitive functioning. The impact of the smoking …

This study compares brain tumor imaging with 3-[123I] iodo-alpha-methyl-L-tyrosine (IMT)
and 3-[123I/125I] iodo-O-methyl-alpha-methyl-L-tyrosine (OMIMT) to that with [methyl-3H]-L-…
