Iodine-123 labeled reboxetine analogues for imaging of noradrenaline transporter in brain using single photon emission computed tomography [PDF]

, 2012
Preliminary investigation of the radioiodinated (S,S)-reboxetine analogue, 123I-INER, in baboons showed this tracer to have promise for imaging the noradrenaline transporter (NAT) using single photon emission computed tomography (SPECT).
