We studied the trigeminal nerve in seven healthy volunteers and six patients with trigeminal neuralgia using the diffusion tensor imaging derived parameter fractional anisotropy (FA). While controls did not show a difference between both sides, there was a reduction of FA in the affected nerve in three of six patients with accompanying nerve-vessel conflict and atrophy. Reversibility of abnormally low FA values was demonstrated in one patient successfully treated with microvascular decompression.
我们使用扩散张量成像衍生参数分数各向异性（FA），对7名健康志愿者和6名三叉神经痛患者的三叉神经进行了研究。对照组两侧未显示出差异，而6名伴有神经血管冲突和萎缩的患者中有3名患侧神经的FA值降低。1例经微血管减压成功治疗的患者，其异常低FA值表现出可逆性。
