Abstract

Background and Purpose: 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 cerebrovascular insufficiency.

Results and Conclusions: Our survay contains chapters on the causes of
cerebral ischaemia, described in methods ofMR 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.
