Abstract
The employment of Magnetic resonance (MR) in investigations of cerebral tissue in health and disease achieved during the last 3 decades great appreciation. Its spectacular results in MR imaging and spectroscopy are especially useful in the domain of brain ischaemia.
Materials and Methods: We have combined practical experience with search in literature to create a review of possible examinations in the field of stroke and chronic cerebro vascular insufficiency. Results and Conclusions: Our survay contains chapters on the causes of cerebral ischaemia, described in methods of MR angiography and Perfusion weighted imaging and chapters on the consequences of ischaemia: Imaging of the ischaemic cascade by classical spin echo sequences, imaging of diffusion, of contrast enhancement and distinction of the surviving parts in the hypoperfused regions.
Magnetic resonance spectroscopy is reported in its proton and phosphorus examinations. Longlasting diminushion of cerebral blood flow with aging is reviewed in the last chapter.
