Absolute quantification in dopaminergic neurotransmission SPET imaging using a Monte Carlo-based scatter correction and fully 3D reconstruction Ros, D; Pavía, J; Cot Sanz, Alberto; Falcón, C; Crespo, C; Sempau Roma, Josep; Pareto, D; Bullich, S; Lomeña, F; Calviño Tavares, Francisco (2005-09)
Restricted access - publisher's policyDopamine transporter (DAT) ligands have been developed for in vivo imaging of the dopaminergic system in SPECT. Although the visual analysis of SPECT images is, in general, suitable for clinical assessment, the accurate ...
Evaluation of geometric, scatter and septal penetration components in fan beam collimators using Monte Carlo simulation Cot Sanz, Alberto; Pareto, D; Sempau, J; Bullich, S; Pavia, J; Calviño Tavares, Francisco; Ros, D (IEEE, 2000)
Restricted access - publisher's policyThe quantitative analysis of SPECT data requires an accurate determination of the collimator point spread function (PSF). The aim of this work is to characterize the PSFs of fan beam and parallel collimators by using ...

Restricted access - publisher's policy3I is a commonly used radioisotope employed in neurotransmitter SPECT studies. In addition to an intense line at 159 keV, the decay scheme of this radioisotope includes a low yield (∼3%) of higher energy photons which ...
Quantification of dopaminergic neurotransmission SPECT studies with I-123-labelled radioligands. A comparison between different imaging systems and data acquisition protocols using Monte Carlo simulation Ros, D; Pavia, J; Calviño Tavares, Francisco; Lomena, F; Crespo, C; Gallego, J; Cot Sanz, Alberto; Falcon, C; Bullich, S; Pareto, D; Aguiar, P; Sempau Roma, Josep (2008-07)
Restricted access - publisher's policyPurpose 123I-labelled radioligands are commonly used for single-photon emission computed tomography (SPECT) imaging of the dopaminergic system to study the dopamine transporter binding. The aim of this work was to ...
