Popis: [18F]FET was synthesized using O-(2′-tosyloxyethyl)-N-trityl-l-tyrosine-tert-butyl ester (TET) precursor. SPE purification of [18F]FET, after radio-synthesis, using neutral alumina column was satisfactory, with radiochemical and enantiomeric purity of >99 %. Decay-uncorrected synthesis yield with 8 mg TET was 19.07 ± 1.3 and 8.76 ± 0.46 % when eluted in 35 and 17 mL of buffered saline, respectively, for practical considerations. O-(2′-hydroxyethyl)-l-tyrosine formed during synthesis could be reduced nine-fold to
