摘要/Abstract

摘要： 目的探讨平衡式快速梯度回波(BFFE)技术对诊断血管压迫性三叉神经痛的价值。方法分析50例原发性三叉神经痛患者常规T1、T2WI、术中所见以及BFFE图像。结果BFFE图像示50例患者均清晰显示了三叉神经。45例患者桥小脑角区微血管均表现为以等信号到略高信号，与桥小脑角池内呈极高信号的脑脊液形成明显对比，血管周围轮廓清晰。42例三叉神经周围有微血管“压迫”的病例中，有17例三叉神经不同程度受压移位，与手术所见一致。结论BFFE技术在诊断血管压迫性三叉神经痛中具有很高价值。

Abstract: To assess the clinical value of the balanced fast field echo (BFFE) in detection of trigeminal neuralgia with blood vessel compression at the cerebellopontine angle. MethodsConventional magnetic resonance imagings and BFFE imagings in 50 cases were retrospectively analyzed. ResultsAll trigeminal nerves of the 50 cases exhibited a clear signal on BFFE imaging and the signal intensities of the blood vessel of the cerebellopontine angle of 45 cases was relatively similar to the trigeminal nerves, which made a sharp contrast with the high signal intensity of the cerebrospinal fluid of the cerebellopontine angle. In 17 of the 42 cases of blood vessel compression of the cerebellopontine angle, the trigeminal nerves exhibited an obvious aversion. ConclusionThe balanced fast field echo is a fast and high performance technique for diagnosing trigeminal neuralgia with blood vessel compression of the cerebellopontine angle.
