Objectives

Narrative objectives1

It has been speculated that synaptic dysfunction is involved in the early stage of dementia, so AMPA receptor PET imaging (AMPA PET), a synaptic functional molecule, may be a new method for diagnosing dementia. In this study, to establish the basis of AMPA PET in dementia patients, we explored the accuracy of estimating the correlation coefficient between the standard uptake value ratio and the non-displaceable binding potential of the cerebral atrophic cortex in dementia patients.
