【摘要】：目的 :探讨3.0 T MRI的SWI对脑梗死侧支循环的诊断及临床意义。方法 :选择35例经临床和影像确诊为脑梗死的患者均行常规头颅MRI、DWI、MRA、SWI检查,10例行SWI复查。观察脑梗死的常规MRI和SWI表现,以及脑梗死区侧支循环的显示程度,得出相应临床NIHSS评分,并进行统计分析。结果:35例脑梗死SWI显示侧支循环的程度:0级9例(25.7%),1级10例(28.6%),2级16例(45.7%)。侧支循环血管显示程度与临床NIHSS评分有明显相关性(r=0.668,P0.01)。结论:SWI能够反映脑血管病变中的血氧饱和度水平改变情况,以及脑梗死是否有侧支循环形成和责任血管情况,对临床制订治疗方案和预后判断具有重要意义。
[Abstract]:Objective: To explore the 3 T MRI SWI on diagnosis and clinical significance of cerebral collateral circulation. Methods: 35 patients with clinical and imaging diagnosis of cerebral infarction underwent routine head MRI, DWI, MRA, SWI examination, 10 patients underwent SWI review. Conventional MRI and SWI manifestations of cerebral infarction, in order to show that the extent of collateral circulation and the cerebral infarction area, the corresponding clinical NIHSS scores, and statistical analysis. Results: 35 cases of cerebral infarction SWI showed collateral circulation degree: 0 of 9 cases (25.7%), 1 (28.6%), 10 cases of grade 2 grade 16 cases (45.7%). The collateral vessels display degree and clinical NIHSS score have significant correlation (r=0.668, P0.01). Conclusion: SWI can reflect the blood oxygen saturation level of cerebral vascular disease and cerebral infarction have changed, the formation of collateral circulation and the responsible vessels, for clinical treatment and prognosis has important significance.

【正文快照】： SWI是利用组织间磁敏感差异和BOLD效应成像,即血管中的脱氧血红蛋白作为内源性对比剂,安全、无创,可显示低流速的静脉,对铁沉积、微出血、静脉及血液代谢产物十分敏感,在出血性脑卒中、脑血管畸形、脑外伤等方面应用前景广泛[1]。目前,国内应用SWI对脑梗死侧支循环形成和脑梗
