摘　　要：目的探讨磁共振三维稳态进动结构相干（3D-CISS）序列在三叉神经痛相关疾病中的应用价值。方法回顾性分析62例以三叉神经痛为主要症状患者的颅脑MRI常规序列和3D-CISS序列图像，其中12例加做增强扫描，对比分析MRI 3D—CISS序列和常规平扫序列对三叉神经相关病变（主要包括三叉神经脑池段周围血管压迫或推移、实性肿瘤和肿瘤样病变）的显示情况，并与手术结果对照。结果手术探查48例发现责任血管；术前MRI 3D-CISS序列诊断三叉神经脑池段周围血管压迫或推移46例，3D—CISS序列显示与手术探查符合率达95．83％；常规序列无法显示三叉神经脑池段周围血管压迫或推移。3D-CISS序列显示实性肿瘤8例，常规平扫序列显示实性肿瘤6例。肿瘤样病变6例于MRI3D-CISS序列和常规平扫序列均得到显示。3D-CISS序列对三叉神经痛相关疾病诊断的敏感度（96．77％）显著高于MRI常规平扫序列（19．35％），差异有统计学意义（P〈0．01）。结论MRI3D—CISS序列对三叉神经痛相关疾病诊断的敏感度高，对术前评估有重要意义，值得临床推广应用。Objective To explore 3D constructive interference insteady state sequence value of re- lated diseases in trigeminal neuralgia. Methods A retrospective analysis of 62 cases of trigeminal neuralgia as the main symptoms of patients with brain magnetic resonance imaging （MRI） routine scan and 3D con- structive interference insteady state （3D-CISS） sequence images, of which 12 cases were enhanced scan, comparative analysis of MRI 3D-CISS sequence and conventional sequence of trigeminal nerve. The lesion showed the condition and was compared with the outcome of the operation. Trigeminal neuralgia-related le- sions mainly included the trigeminal nerve brain pool around the vascular compression or transition, solid tumors and tumor-like lesions. Results Preoperative MRI 3D-CISS sequence was used to diagnose the vas- cular compression or metastasis of the trigeminal nerve pool segment in 46 cases. Forty-five patients were found to be responsible blood vessels. The 3D-CISS sequence showed 95.83% coincidence with surgical ex- ploration. The routine sequence could not show the trigeminal The brain around the brain was forced or pushed. 3D-CISS sequence showed eight cases of solid tumors, routine scan showed six cases of solid tumors. Tumor-like lesions were shown in 6 cases of MRI3D-CISS sequences and routine plain scan sequences. The sensitivity of 3D-CISS sequence to trigeminal neuralgia-related disease was 96. 77% , and the sensitivity of MRI routine scan to trigeminal neuralgia was only 19. 35%. There was significant difference in the sensitivity of 3D-CISS sequence and conventional plain scan sequence to trigeminal neuralgia-related diseases （P 〈 0. 01 ）. Conclusions MRI 3D-CISS sequence has a significant advantage in trigeminal neural- gia-related disease, and patients with trigeminal neuralgia should routinely use 3D-CISS sequences.
