摘要
目的通过脑池段后组脑神经3D—CISS序列与3D—TSE序列成像质量的比较,评估3D—CISS序列对脑池段后组脑神经及其病变显示的作用。方法对45例正常体检者和12例患有各种后组脑神经异常症状的病人进行3D—CISS序列、3D—TSE序列扫描,对后组脑神经成像进行评分。结果舌咽、迷走、副神经及舌下神经在3D—CISS、3D—TSE序列的显示率依次为:100%、57.1%;100%、52.3%;100%、41.1%;91.0%、59.3%。应用3D—CISS序列:对8例血管性神经痛病人显示了责任血管压迫点,对3例后组脑神经微小肿瘤进行了显示,对1例蛛网膜囊肿病人显示了压迫点。结论对于被脑脊液围绕的后组脑神经显示成像,3D—CISS序列是较好的选择。
Objective To evaluate the efficacy of 3D - CISS on image quality of posterior nerves surrounded by CSF when compared with that of3D -TSE. Method A total of 45 volunteers and 12 patients with abnormality of posterior cranial nerves were examined using 3D - CISS and 3D - TSE sequences respectively. The image quality were graded for g|ossopharyngeal nerve, vagus nerve, accessory nerve, hypoglossal nerves ( CN IX, X , XI, XH ) and their related arteries. Results The identification rates for cisternal segment of posterior nerves were as follows: glossopharyngeal nerve ( 100% in 3D - CISS and 57.1% in 3D -TSE) ,vagus nerve( 100% in 3D -CISS and 52. 3% in 3D -TSE) ,accessory nerve( 100% in 3D - CISS and 41.1% in 3D - TSE) ,hypoglossal nerves(91.0% in 3D - CISS and 59.3% in 3D - TSE) ;12 patients with pathological changes in posterior nerves were all displayed well, among them 8 were pressed by artery, 1 by arachnoid cyst,3 caused by tumors. Conclusions 3D -CISS sequence is preferable when imaging posterior cranial nerves surrounded by CSF.
