In clinical practice, Alzheimer's disease (AD), multi-infarct Dementia (MID) and depression are often difficult to differentiate and may coexist. This study reports the findings of CT and MRI focused on hippocampal atrophy (HA). Quantitative volumetric MRI measurements of the hippocampus showed a reduced volume in AD patients compared to normal controls(More)
MRT is of considerable significance in the investigation of epilepsy because of its ability to render soft tissue contrast for the demonstration of structural lesions. The present retrospective study consists of an analysis of MRT findings in operatively confirmed, circumscribed temporal tumours and in hippocampal sclerosis. The examinations were performed(More)
In 62 patients spinecho or gradientecho sequences compensated for motion were compared with corresponding non-compensated sequences. Compensation during MRT reduces those artifacts which are caused by regular motion. This is particularly effective during examination of the brain stem, spinal canal and the heart. The improved demonstration of the morphology(More)
Contrast performance in MR tomography is influenced by the choice of technical parameters such as pulse repetition time (TR), echo time (TE) and inversion time (TI) in the same manner as by differences in the tissue parameters relaxation time and proton density. To optimise image contrast it is therefore suggested to preselect the imaging sequence. Such(More)
