体感诱发电位和磁共振弥散加权成像在急性脑梗死中的应用

目的:探讨弥散加权成像和躯体感觉诱发电位在脑梗死中的应用价值。方法:对71例急性脑梗死患者进行常规MRI、DWI及SEPs检查,在入院及发病2个月时对患者进行NIHSS评分,并对各项指标进行分析。结果:71例患者中,SEPs异常者46例(64.79%);三组患者NIHSS1及NIHSS2评分组间两两比较均有差异。DWI阳性率明显高于常规MRI;梗死体积与患者的NIHSS呈正相关关系。结论:SEPs结合DWI检查,能对急性脑梗死做出早期诊断,并对早期判断病情程度、评估预后提供客观依据。

SEPs and DWI in Acute Cerebral Infarction

Objective：To evaluate the application value of DWI and SEPs in acute cerebral infarction.Methods：The conventional MRI,DWI and SEPs were examined in 71 patients with acute cerebral infarction,All the patients＇ NIHSS score were evaluated when on admission and two months after the onset.Results：Forty-six of the 71 patients had abnormal SEPs results;there were significant differences in the NIHSS1 and NIHSS2 score of the three group（P〈0.05）.DWI had higher positiverate indetecting infarction than conventional MRI;the infarct volume had obvious positive correlation with the NIHSS.Conclusion：SEPs associated with DWI could provide more accurate diagnosis of acute cerebral infarction and could provide the imaging evidence for clinician to evaluate the pathogenetic condition and prognosis.
