DaT scan transaxial SPECT sections for: (a) a patient with essential tremor, showing high symmetric uptake in both caudate and putamen regions; (b) a patient with Parkinson’s disease, showing markedly reduced putamen activity and asymmetric caudate activity; (c) a patient with dementia with Lewy bodies, showing nearly absent caudate and putamen uptakeBack to article page
