MR-imaging of non-Alzheimer's dementia

Abstract

Up to now, computerized tomography (CT) and MR-imaging have been used for the morphological assessment of dementia patients, while MRI has become the structure imaging modality of choice. With the advent of fast and ultrafast sequences provided by higher gradient field strengths, functional MR studies like diffusion, perfusion and activation studies become available. The greatest advantage of MR is its versatility including MR-imaging, 3D postprocessing, MR-volumetry, MR-spectroscopy, MR-angiography, MR-perfusion and diffusion imaging as well as functional MRI activation studies. The application of the multimodal MR-technology in dementia disorders has already begun and has to be validated in clinical practice. The multimodality of MR represents a diagnostic challenge for the future with the hope, that the diagnostic efficacy, which has to be proven, is also followed by an improvement of patients care and prognosis.
