The applicability of total distribution volume (DVt) as an alternative to binding potential (BP) was investigated for neuroreceptor mapping by positron emission tomography (PET). BP is defined as a representative quantity of receptor density. However, for making parametric images of BP, a reference region where an aimed receptor has a very low density is assumed to exist in a target region such as...
The Logan plot is a widely used algorithm for the quantitative analysis of neuroreceptors using PET because it is easy to use and simple to implement. The Logan plot is also suitable for receptor imaging because its algorithm is fast. However, use of the Logan plot, and interpretation of the formed receptor images should be regarded with caution, because noise in PET data causes bias in the Logan...
