Summary
Recent advances in magnetic resonance spectroscopy permit noninvasive study of brain metabolism in vivo,31P spectroscopic imaging being the method for evaluation of localized phosphorous metabolism. Experimentally, an ischemic-hypoxic brain insult is characterized by depletion of high energy metabolites. These changes are seen immediately after an ischemic insult. We had the opportunity of carrying out31P spectroscopic imaging of hyperacute cerebral infarction, while MRI and CT were negative. Cerebral infarction of the middle cerebral artery territory was suggested by31P spectroscopic imaging, which was closely consistent with a later-develo** region of low density on CT. In cerebral infarction, early detection of the lesion is a useful pointer to the patient's prognosis, making31P spectroscopic imaging a potential tool.
