摘要
目的探讨磁共振弥散加权成像(DWI)在急性脑梗死中的临床应用价值。方法对52例临床拟诊为急性脑梗死患者,行头颅CT检查,在磁共振常规序列的基础上行DWI,分析其影像学表现。结果 52例中,超急性期脑梗死11例,急性期41例,超急性期、急性期脑梗死在DWI上表现为高信号,并且DWI可显示常规磁共振不能显示的病变范围。结论 DWI对急性期脑梗死有较高的敏感性,能发现常规磁共振不能发现的超急性期脑梗死,为临床提供了切实可行的影像学资料。
Objective To explore the clinical application value of diffusion- weighted imaging（DWI） of magnetic resonance for acute cerebral infarction. Methods The results of DWI and traditional CT and routine MRI in 52 patients with acute cerebral infarction were analyzed and applied. Results In 52 cases, 11 eases were ultra- acute cerebral infarction,41 eases were acute cerebral infarction, all eases were shown abnormal high sign on DWI, and DWI can show lesion scopes which may not be shown on routine MRI. Conclusion DWI is of higher sensitivity compared with routine MRI in diagnosing acute cerebral infraction detecting early infarction lesions, which is diffieult to be displayed on routine MRI, thus offering reliable imaging data for clinical.
