ABSTRACT: A 76-year-old woman underwent 123I-FP-CIT brain SPECT due to postural reflex impairment. The transverse slices demonstrated increased uptake in the right middle cerebral artery territory. MR images obtained 2 weeks earlier showed cerebral infarction in the corresponding area. 123I-FP-CIT has high binding affinity for dopamine transporters, especially in the nerve endings of nigrostriatal dopaminergic neurons.
