| Popis: | SummaryThis article describes the use of non-invasive magnetic resonance (MR) methods for the characterization and monitoring of the pathophysiology of experimental brain injury in laboratory animals as a function of time and treatment. The impact of MR in brain research is primarily due to its non-invasive nature, thereby enabling repeated measurements in long-term studies, and due to the type of information that it provides. MR imaging (MRI) enables the measurement of the morphology/anatomy as well as the functional status of tissues under in vivo conditions. Compared to other in vivo imaging modalities, MRI has a high spatial resolution and allows for a remarkable soft tissue differentiation. MR spectroscopy (MRS) provides information on the biochemical/metabolic status of tissues. MR methods which have proven valuable in animal studies, can be readily translated to the clinical situation where MR-based diagnosis and treatment planning play a rapidly increasing role.After a short introduction into the principles of MR, we will illustrate the remarkable versatility of MR in research on brain injury from recent animal studies. Examples will be mainly drawn from experiments on early injury in focal cerebral ischemia and from research on mechanical brain trauma and excitotoxic lesions. The article ends with a brief description of the perspectives of MR in neuropsychiatry. |
