A technique significantly like the reconstruction of computed tomography (CT) and single-photon emission computed tomography (SPECT) data is more generally utilized, even though the data set collected in PET is significantly poorer than CT, so reconstruction techniques are a lot more tough (see Image reconstruction of PET).
An example of a PET scan is under and it reveals: in the leading panel a standard scan, in the middle panel abnormalities in the putamen (red uptake in the figure) in a patient with Parkinson’s disease, and in the lower panel a return to an almost normal scan following the introduction of levodopa.
