【摘要】 目的研究MRISPGR序列对三叉神经痛病因诊断的临床价值。方法采用MRI-TOF序列扫描124例三叉神经痛患者的脑干段,并作多平面重建,评判所见三叉神经周围有无血管及其与血管的关系。结果124例中30例神经与血管无关系,94例为有关系组,有症状组三叉神经所见责任血管与神经夹角(74.5,%73/98)>450,无症状组(30.1%25/83)结论MRI对血管压迫性三叉神经痛的责任血管的评估非常有价值。更多还原

【Abstract】 Objective To evaluate the clinical value of MRI sequence in the etiological diagnosis of-trigeminal neuralgia(TN).Methods Three dimensional-of-flight(3D-TOF) sequence was perfomed in 134 patients with triheminal neuralgia were reconstrueted.judgment was made on if there some vessesl close to the trigeminal nerve.Results 94 cases trigeminal nerves of all 134nerves can be detected offending vessels on MRTA images,the rest 28 were symptomatic.In74.5% cases(79/145) of the symptomatic group the angle between the vessel and the nerve is larger than 45°,in30.1% cases(25/134)in the asymptomatic group the angle is larger than 45°.Conclusion MRI is an useful tool to evaluate the offending vessels of vascular compressive trigeminal neuralgia.更多还原
