目的：评价高分辨率3D-FIESTA+c成像及图像处理技术显示脑神经及其病变的价值。方法采用3D-FIESTA+c对20例健康志愿者和20例临床疑是因血管等原因压迫相应脑神经具有临床症状的患者进行扫描及图像后处理。由2名神经放射学医师根据20名健康志愿者480支脑神经显示的清晰程度分为清晰、较清晰、不清晰3个等级，清晰和较清晰定义为显示，不清晰定义为未显示；临床病例中，脑神经与血管关系分为无接触、接触、压迫。结果12对脑神经显示率分别为：嗅神经84.3%，视神经100%，动眼神经100%，滑车神经43.8%，三叉神经100%，外展神经100%，面神经100%，前庭蜗神经100%，舌咽神经、迷走神经及副神经复合体100%，舌下神经47.1%。20例脑神经症状患者，16例确诊为脑神经与周围血管接触或压迫，且均被临床治疗证实。结论高分辨3D-FIESTA+c成像与图像后处理技术相结合可显示脑神经及其病变，能准确定位血管走向及其与脑神经的关系，为临床医生提供准确、全面的影像学资料。

Objective To investigate the applying value of 3D-FIESTA+c MRI sequences for cranial nervesⅠ-Ⅻ.Methods 3D-FIESTA+c as used in 20 volunteers and 20 patients with complaint of cranial nerves.480 nerves were evaluated. Two radiologists independently divided the imaging findings in to 3 grades:completely visualized,partially visualized,and not visualized. The first two grades were defined as visualization and the last grade was no visualization.The relationship between nerves and surrounding vessels were divided into grades:notcontact, contact, compression.Results The rate of visualization of these cranial nerves with 3D-FIESTA+C sequences were as follows respectively: nerveⅠ(84.3%); nerveⅡ(100%); nerveⅢ(100%); nerveⅣ(43.8%); nerveⅤ(100%); nerveⅥ(100%); nerveⅦ(100%); nerveⅧ(100%); nerveⅨ-Ⅺcomplex(100%); nerveⅫ(47.1%).16 of 20 patients with complaint of cranial nerves displayed nerve had vascular compression or contact. Conclusions 3D-FIESTA+c sequence can show detailed anatomy of the cranial nerves and relationship between nerves and surrounding vessels,to help clinical treatment.
