摘要
目的:从国内外磁共振成像近年来对脑梗死预后的研究出发,探讨应用不同磁共振成像序列和方法对脑梗死患者的预后进行早期判断的价值。资料来源:应用计算机检索Medline1985-01/2004-4期间的相关文章,检索词“MRI,cerebralinfract,prognosis”,并限定文章语言种类为English。同时计算机检索万方数据库1985-01/2004-04的与MRI早期判断脑梗死临床预后的文献,检索词“磁共振,脑梗死,预后”,并限定文献语种为中文。资料选择:就检索到的132篇文献进行筛选,选择其中为随机临床试验的研究,并有可靠的连续观察结果和预后评分,并排除综述类文献。资料提炼:将筛选到的文献按不同的MRI成像序列,排除其中内容重复的研究,其中27篇为MRI与脑梗死临床预后的相关性研究。资料综合:27篇文献共包括650余例患者,分别应用MRI对经神经内科治疗的脑梗死患者的临床预后进行早期判断。用于脑梗死的MRI脉冲序列包括快速自旋回波T2加权脉冲序列(T2WI)、快速反转恢复成像自由水抑制技术、弥散加权成像、脑血流灌注加权成像、磁共振波谱、磁共振血管成像和血氧水平依赖成像。结论:综合应用各种MRI检查技术可以为脑梗死患者提供比较准确的预后资料。
OBJECTIVE： From the study of MRI in the prognosis of cerebral infraction in recent years, and discuss the value of different MRI methods in estimating the final outcome of patients with cerebral infraction. DATA SOURCES： An online search of Medline database was undertaken to identify the relevant articles published in English from January 1985 to April 2004 with keywords of ＂MRI, cerebral infraction, prognosis＂. Meanwhile, Chinese articles related to the clinical prognosis of cerebral infarction evaluated by MRI at early period were retrieved in Wanfang database published between January 1985 and April 2004 by using the same keywords in Chinese. STUDY SELECTION： The retrieved 132 articles were screened, and the randomized clinical trials with reliable successive observational results and prognostic scores were selected, and the reviews were excluded. DATA EXTRACTION： The screened articles were classified according to different MRI rank, the articles with the same content were excluded, and there were 27 articles about the correlation between MRI and the clinical prognosis of cerebral infraction. DATA SYNTHESIS： More than 650 patients were involved in the 27 articles, which evaluated the clinical prognosis of patients with cerebral infraction in the neurological departm.ent With MRI at early period. The MRI pulse rank used for cerebral infarction included fast spin echo T2 weighted image （T2WI）, fluid-attenuated inversion recovery free water suppression, diffusion weighted image, perfusion weighted image, magnetic resonance spectrum, magnetic resonance angiography and blood oxygenation level-dependent image. CONCLUSION： Synthetically application of different MRI techniques could provide relatively confirmed prognosis for patients with cerebral infraction.
