Same day cerebral perfusion and dopamine transporter imaging for differential diagnosis of cerebral impairment

When cognitive impairment is first evident it can be difficult to distinguish between different conditions, such as idiopathic Parkinson's disease and Lewy body dementia, which exhibit shared symptoms such as rigidity, tremor, issues with speech or gait disturbance [1]. When Lewy body dementia is suspected, imaging both cerebral perfusion and dopamine transporter function can eliminate other possible conditions (idiopathic Parkinson's disease, cerebral vascular disease, Alzheimer's disease or frontotemporal dementia) [2].
