目的探讨弥散张量纤维束成像在脑梗死中的应用。方法 2010年3月至2012年3月份收治脑梗死148例,进行磁共振成像系统重建三维弥散张量纤维束成像图,观察白质纤维束损伤情况,对各组病例进行测量ADVAv值、FA值,并与健侧相应区进行比较。结果急性期48例中,白质纤维束变形移位18例;亚急性期71例,白质纤维束变形移位48例;慢性期29例,白质纤维束变形移位20例。结论通过常规MRI、弥散加权成像和弥散张量纤维束成像进行充分结合对脑梗死进行诊断,对病灶定位更准确,对白质纤维束损伤程度充分判断,通过对平均表观弥散系数、各向异性分数值观察能够对脑梗死更精确的临床分期。
Objective To investigate the application of diffusion tensor fiber bundle imaging in cerebral infarction. Methods From March 2010 to March 2012, 148 cases of cerebral infarction were treated. Magnetic resonance imaging system was used to reconstruct the three-dimensional diffusion tensor fiber bundle. The damage of white matter fiber bundle was observed. The ADVAv, FA, And compared with the contralateral health area. Results In 48 cases of acute phase, 18 cases of white matter dislocation were translocated, 71 cases of subacute stage, 48 cases of white matter dislocation and displacement, 29 cases of chronic phase and 20 cases of white matter dislocation. Conclusion The conventional MRI, DWI and DSF can be used to diagnose cerebral infarction. The localization of the lesions is more accurate and the degree of damage to the white matter fiber bundle can be fully judged. The average apparent diffusion coefficient, anisotropy Fractional observation can be more accurate clinical stage of cerebral infarction.
