The Role of Brain Single Photon Emission Computed Tomography in the Diagnosis of Primary Progressive Aphasia Arch Neurol 48:1257-1260, McDaniel,K.D.,et al, 1991 See this aricle in Pubmed Article Abstract We present two cases of primary progressive aphasia studied with neuropsychologic measures,computed tomography or magnetic resonance imaging,and single-photon emission computed tomography with technetium Tc99m-labeled hexamethylpropyleneamine oxime.Clinical and neuropsychologic observations revealed a marked,progressive loss of language functions over time with relative preservation of nonlanguage cognitive functions in both patients.The brain single-photon emission computed tomographic scan revealed marked left posterior frontal and minimal left temporal hypoperfusion in case 2.The value of brain single-photon emission computed tomography in distinguishing primary progressive aphasia from Alzheimer's disease is described.
