摘 要: | 目的探讨3.0TMR3D-COSMIC成像序列对Ⅰ-Ⅻ对脑神经脑池段显示的临床价值。方法采用3.0TMR扫描仪对20例健康志愿者和10例疑因血管等原因压迫相应颅脑神经产生临床症状的患者进行MR检查。并由两名神经放射学医师根据20例志愿者480支颅神经显示的清晰程度分为以下3个等级:清晰、较清晰、不清晰,前两者定义为显示,后者定义为未显示,而神经与血管的关系分为无接触、接触、压迫。结果脑神经在3D-COSMIC序列的显示率分别为:嗅神经(86%),视神经(100%),动眼神经(97%),滑车神经(23%),三叉神经(100%),外展神经(90%),面神经(100%),前庭蜗神经(100%),后组颅神经复合体(舌咽神经、迷走神经、副神经)(63%、100%、53%),舌下神经(40%)。10神经症状患者3例显示神经与周围血管接触或压迫,且均为神经外科手术证实。结论 3D-COSMIC成像序列可以较为清晰显示除滑车神经之外12对脑神经脑池段形态、走形及其与血管的关系,尤其能很好显示Ⅱ、Ⅲ、Ⅴ、Ⅵ、Ⅶ、Ⅷ、Ⅹ7对脑神经脑池段,为临床诊治提供更大的指导作用。

Abstract: | Objective To investigate the applying value of To compare 3D-COSMIC MRI sequences for cranial nervesⅠ-Ⅻ.Methods 3D-COSMIC were used in 20 volunteers and 10 patients with complaint of cranial nerves.480 nerves were evaluated.Two radiologists independently divided the imaging findings into 3 grades:1(completely visualized),2(partially visualized),and 3(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:1(notcontact),2(contact),3(compression).Results The rate of visualization of these cranial nerves with 3D-COSMIC sequenceswere as follows respectively:nerveⅠ(86%) ;nerveⅡ(100%);nerveⅢ(97%);nerve Ⅳ(23%);nerve Ⅴ(100%);nerve Ⅵ(90%);nerve Ⅶ(100%);nerve Ⅷ(100%);nerve Ⅸ-Ⅺ complex(63%,100% and53%);nerve Ⅻ(40%).3 of 10 patients with complaint of cranial nerves displayed nerve had vascular compression or contact.Conclusion 3D-COSMIC sequence can show detailed anatomy of the cranial nerves and relationship between nerves and surrounding vessels.especiallyⅡ、Ⅲ、Ⅴ、Ⅵ、Ⅶ、Ⅷ、Ⅹcranial nerves,to help clinical treatment. |
