目的：探讨GE0.35T磁共振脑功能成像在急性缺血性脑血管病的临床应用。方法对我院2009年5月～2010年5月收治的180例急性缺血性脑血管病患者进行MRI、DWI和PWI扫描。结果在180例患者中，有20例属于短暂性脑缺血发作，有160例属于急性的脑梗死。在这160例的急性脑梗死患者中，有120例患者是在6h内发作的，还有40例患者则是在6～12h发病的。在6h以内发病的120例患者中的，PWI扫描结果大于DWI扫描结果的有54例，PWI扫描结果和DWI扫描结果相等的有0例。在6～12h之间发病的40例患者中，有24例PWI扫描结果大于DWI扫描结果，还有8例PWI扫描结果和DWI扫描结果相等。结论 GE0.35T磁共振脑功能成像是一种能明显提高急性缺血性脑血管病变显示率的简便方法，值得进行临床推广。

Objective To investigate the clinical applications of functional magnetic resonance imaging(fMRI) in acute ischemic cerebrovascular disease with 0.35T unit. Methods 180 patients with acute ischemic cerebrovascular disease were selected from the hospital of Heilongjiang Province between May 2009 to May 2010. All above patients have completed the MRI examination, including DWI and PWI. Results The 180 patients were divided into 2 groups, the transient cerebral ischemic attack group contained 20 patients, the acute cerebral infarction group contained 160 patients. In the patients with acute cerebral infarction, the number of patients within 6 hours onset of super-early stage cerebral infarction was 120, and the number of patients with 6-12 hours of onset of acute cerebral infarction was 40. In 120 patients within 6 hours of onset, 54 patients' abnormal perfusion regions were larger than the hyperintense areas shown by DWI, no patient' perfusion regions was as large as the hyperintense areas shown by DWI. In 40 patients with 6-12 hours of onset, 24 patients' abnormal perfusion regions were larger than the hyperintense areas shown by DWI, 8 patients' perfusion regions were as large as the hyperintense areas shown by DWI. Conclusion fMRI is a simple method which can effectively display the lesions of ischemic cerebrovascular disease, its clinical value is of great worth.
