Single photon emission computed tomography (SPECT) and MRI coregistration have been assessed to characterize striatal dopamine D2/D3 receptor (D2/D3R) availability in rats following injection of the D2 and D3R radioligand [123I] iodobenzamide ([123I]IBZM). High-resolution SPECT data were obtained with a pinhole collimator. In order to precisely estimate(More)
Radiolabeling of nanoparticles (NPs) has been performed for a variety of reasons, such as for studying pharmacokinetics, for imaging, or for therapy. Here, we describe the in vitro and in vivo evaluation of DTPA-derivatized lipid-based NP (DTPA-NP) radiolabeled with different radiometals, including (111)In and (99m)Tc, for single-photon emission computed(More)
