Magnetic Resonance Spectroscopy of Patients with Acute Cerebral Infarction / 대한뇌혈관외과학회지

ABSTRACT

OBJECTIVE: MR spectroscopy is a noninvasive method of monitoring in vivo metabolite concentration changes over time. In this study we evaluated the usefulness of combined magnetic resonance imaging and spectroscopy on the diagnosis of cerebral infarction. METHODS: Combined magnetic resonance imaging and spectroscopy investigations were carried out with 1.5-T system in 18 volunteers, 10 patients with acute infarction (< 8 hours). RESULTS: Acute ischemic infarctions were characterized by decreased N-acetyl aspartate and elevation of lactate. CONCLUSION: Metabolic alterations in ischemic tissue can be monitored.
