Axial 123I-FP-CIT DaT-SPECT images in a patient with dementia with Lewy bodies (A) and a patient with Alzheimer disease (B). Axial 123I-FP-CIT DaT-SPECT images in a patient with dementia with Lewy bodies (A) and a patient with Alzheimer disease (B). Note that the DaT-SPECT study helped to distinguish the 2 causes of dementia with the patient with dementia with Lewy bodies exhibiting a Catafau and Tolosa2 type 3 pattern of abnormal striatal uptake; in contrast, the patient with Alzheimer disease demonstrates normal striatal uptake. Images from both patients have low gain as demonstrated by low background activity. T.C. Booth et al. AJNR Am J Neuroradiol 2015;36: ©2015 by American Society of Neuroradiology
