摘　　要：三叉神经痛(trigeminal neuralgia,TN)是老年人的常见病,是一种独特的外周神经痛,严重影响患者的生活和工作。神经血管压迫/接触(neurovascular compression/contact,NVC)已经证实是TN的主要病因,术前识别NVC有助于选择TN的适当治疗方案。目前微血管减压术(microvascular decompression,MVD)是TN患者最有效的治疗方法,而MVD能否成功与责任血管判定的精准性有密切的关系。常规MRI序列无法清楚地显示三叉神经与邻近血管的关系。随着高分辨率(high resolution,HR)MRI技术的快速发展和普及,HR MRI序列如三维稳态序列等,可以用来评估TN患者NVC的大部分特征。同时联合HR MRI序列的多模态成像、血流动力学评估及扩散张量成像能够提高诊断准确度,为MVD的临床发展提供有力的保障。本文综述了3D HR MRI技术在TN诊断中的应用进展。Trigeminal neuralgia(TN)is a common disease in the elderly.It is a unique form of neuropathic pain,seriously affect the life and work of patient.Neurovascular compression/contact(NVC)is the main cause of TN.Preoperative identification of NVC has an impact on the determination of appropriate treatment for TN.Currently,microvascular decompression(MVD)is considered the most effective treatment for patients with TN.The key to the success of MVD is closely related to the accuracy of responsibility vessel determination.The conventional MRI sequences can not clearly depict the relationship between the trigeminal nerve and adjacent vessels.However,with the rapid development and the popularity of high resolution(HR)MRI technology,HR MRI sequences,such as three-dimensional(3D)steady-state sequences,can be used to assess most of the characteristics of NVC in TN patients.At the same time,multimodal imaging combined with HR MRI sequences,hemodynamic assessment and diffusion tensor imaging can improve the accuracy of diagnosis,which provides a powerful guarantee for the clinical development of MVD.This paper reviews the progress of 3D HR MRI technology in TN diagnosis.
