【摘要】：目的:探讨磁敏感加权成像(SWI)在诊断急性脑梗死责任动脉血栓、评估患者病情及预后的临床应用价值。材料与方法:32例急性脑梗死患者均在3.0T MR扫描仪上行常规MRI、DWI、MRA和SWI检查。采用SWI-mIP图观察颅内动脉血栓。将动脉血栓在SWI上的显示定义为血管磁敏感征(SVS)。运用统计学分别计算SVS与急性梗死灶面积、入院时临床NIHSS评分及近期预后的相关性。结果:32例急性脑梗死患者中16例显示SVS阳性,阳性率为50%。SVS与MRA显示的动脉病变区位置吻合,并主要发生在大脑中动脉近段。SVS阳性患者急性梗死灶面积大于SVS阴性患者,差异有统计学意义(P0.05)。SVS的显示与患者入院时NIHSS评分、近期预后均有相关性(P0.05)。结论:SWI能提供急性脑梗死灶的责任动脉血栓,为临床选择治疗方案、评估病情及预后提供客观的影像学证据,SWI可常规应用于急性脑梗死患者。
[Abstract]:Objective: to evaluate the clinical value of magnetic sensitivity weighted imaging (SWI) in the diagnosis of acute cerebral infarction (ACI) and the evaluation of patient's condition and prognosis.Materials and methods 32 patients with acute cerebral infarction were examined with MRA and SWI on 3.0T Mr scanner.Intracranial arterial thrombosis was observed by SWI-mIP.The display of arterial thrombus on SWI was defined as magnetic sensitivity sign.The correlation between SVS and the area of acute infarction, the clinical NIHSS score at admission and the short term prognosis were calculated statistically.Results SVS was positive in 16 of 32 patients with acute cerebral infarction. The positive rate was that the location of the lesion area of artery displayed by 50%.SVS and MRA was identical, and the area of acute infarction in the patients with positive middle cerebral artery was larger than that in patients with SVS negative.The difference was statistically significant (P 0.05). The display of SVS was correlated with the NIHSS score at admission and the short-term prognosis (P 0.05).Conclusion SWI can provide the responsible arterial thrombus for acute cerebral infarction, and provide objective imaging evidence for clinical treatment, evaluation of illness and prognosis. SWI can be routinely used in patients with acute cerebral infarction.
