The authors present neuroradiological semeiotic elements on Magnetic Resonance (MR) in some more frequent forms of organic dementia including Alzheimer's, vascular dementia, frontotemporal dementia, and Creutzfeld- Jakob's disease, emphasizing useful aspects in diagnosis. MR assists good anatomical evaluation of the gray matter, cortical and subcortical structures, involved in diverse forms of organic dementia and contributes also in early phases of diagnosis. High spatial resolution permits identification of indices for anatomic evaluation of these structures, specifically the superficial and volumetric linear indices which are utilized in the study of mesial-temporal structures in Alzheimer's disease. MR with 'diffuse and focal atrophy' morphology and its quantification also provides information on signal intensity of encephalic structures in various sequences. In particular, the evaluation of alterations of white matter, which in diverse measure and mode may be associated with organic dementia, constitute an element in differential diagnosis. Moreover, signal analysis of the white and gray matter may be considered not only 'visual' but may also be quantified using sample processes or computerized tissue segmentation.
