目的研究强化三维损毁梯度回波序列(3D-SPGRI)在三叉神经痛微血管减压(MVD)术前评价和病例选择中的作用.方法 33例三叉神经痛患者行高分辨率强化3D-SPGRI及三维脑血管成像(3D-MRA)扫描,观察三叉神经出脑干段神经及邻近血管关系,并与MVD术中观察结果对比.结果 33例患者中29例显示与疼痛侧别一致的神经血管接触或压迫并行显微手术减压,手术证实,其中27例MR图像符合术中所见,所有手术患者术后疼痛完全缓解.结论 3D-SPGRI结合3D-MRA能够清晰显示脑池段三叉神经及其邻近血管,为MVD术前评价、病例选择、判断预后提供有价值的信息.

Objective To study the preoperative high resolution three-dimensional MR imaging of idiopathic trigeminal neuralgia,demonstrating the use in selection of patients and planning of the treatment.Methods The enhanced three-dimensional spoiled gradient.recalled imaging and three-dimensional MR angiography with 3-T MRI system were used to detect the anatomic relationship of neural and vascular structures at the trigeminal root entry zone preoperatively,surgical findings served as a reference to compare the MR visualization with the exact anatomic relations.Results Twenty.nine of 33 patients,who had the MRI positive vascular contact or compression.which was consistent to the symptom side,received the microvascular decompression(MVD).surgical findings revealed neurovascular conflicts in all subjects,27 of 29(93%)were consistent to the imaging results,all the patients treated with MVD had the immediate complete pain relief.Conclusions High-resolution MR imaging successfully demonstrated its usefulness in detecting the neurovascular contact at the trigeminal root entry zone-thereby facilitating the selection of patients who were most likely to benefit from MVD.
