摘要
目的：探讨分析磁共振弥散张量白质纤维束示踪成像对急性脑梗死患者康复的评估价值。方法：回顾性分析2010年10月-2012年12月郑州市第二人民医院神经内科明确诊断为脑梗死的75例患者的临床资料，利用磁共振扫描仪，对脑梗死患者进行常规磁共振（magnetic resonance imaging, MRI），依照皮质脊髓束受累情况将患者分成三组，在患者起病后的不同时期，发病后3 d内（急性期）、发病后8-14 d（慢性早期）、发病后30~60 d（慢性期）依照美国国立卫生院卒中量表（Nation Institutes of Health Stroke Scale, NIHSS）对患者进行神经功能评分，利用统计学方法对不同级别皮质脊髓束损伤组患者不同时期的神经功能评分分别进行比较，评价该神经束的受累情况与脑梗死患者预后变化的关系。结果：随着发病时间的不断延长，三组患者的NIHSS评分均呈现明显降低的趋势，差异有统计学意义（P〈0.05）。组间比较发现，在不同时期，B、C组患者的NIHSS评分均显著高于A组，组间比较差异均有统计学意义（P〈0.05）；C患者的NIHSS评分均显著高于B组，两组比较差异均有统计学意义（P〈0.05）。结论：磁共振弥散张量白质纤维束示踪成像可准确定位梗死灶，有助于预测急性脑梗死患者运动功能的恢复，值得在临床上推广应用。
evaluated according to nation institutes of health stroke scale（NIHSS）, which were contrastively analyzed between different time points and groups using statistical methods. Result：NIHSS scores of patients in all groups showed rising trend following time, and the difference between time points had statistically significant（P〈0.05）. Compared among groups, the NIHSS score of the second group was significantly higher than that of the first group（P〈0.05）, and that of the third group were significantly higher than that of the second group too（P〈0.05）. Conclusion：White matter tractography by diffusion tensor imaging can accurately position infarction lesions and help to predict the recovery of motor function of patients with acute cerebral infarction, which was worthy of clinical popularization and application.
