Abstract

Recent technical advances in MR imaging have enabled the authors to investigate early physiological changes in acute ischemic stroke lesion. Diffusion and perfusion MR imaging can provide clinically useful information not only for early detection of ischemia, but also for prediction of tissue outcome. MR spectroscopy is a potentially powerful tool to study acute stroke, but its clinical value has been limited due to long examination time and low spatial resolution.

摘要

磁共振成像（MR）的最新技术进展使作者能够研究急性缺血性脑卒中病变的早期生理变化。扩散加权成像（DWI）和灌注加权成像（PWI）不仅能为早期缺血的检测提供临床有用信息，还能用于预测组织转归。磁共振波谱成像（MRS）是研究急性脑卒中的一种潜在有力工具，但由于检查时间长和空间分辨率低，其临床价值受到限制。
