Dementia, depression and the CT scan.
Hounsfield's Nobel prize for the invention of computed tomography (CT) was well-deserved recognition of a major advance in medical technology, an innovation which produced immediate rewards in the diagnosis and management of space-occupying lesions (SOL), and justified high capital costs (Jacobsen et al. 1976; Thomson, 1977).

متن کاملBrain atrophy in dementia judged by CT scan ranking.
In order to further investigate the relationships of brain atrophy, age, and dementia, computed tomographic (CT) scans on two groups of subjects aged 65-80 years were rank-ordered according to ventricular and sulcal size. Each group contained subjects with mild senile dementia of the Alzheimer type (SDAT) and matched controls. In both experiments there was a strong correlation between these ran...
متن کاملRelationship between cognitive and morphological asymmetry in dementia of the Alzheimer type: a CT scan study.
In this study we investigated the association between morphological asymmetry and patterns of cognitive ability in dementia of Alzheimer's type (DAT). Digitized CT scans were used to estimate volumetric parameters of the brain. The volume of the cranium, brain parenchyma, the subarachnoid space, and lateral ventricles was computed. The volume of the subarachnoid space was used as an index of co...
