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,对后组腑神经成像进行评分.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 of 3D-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 glossopharyngeal nerve、vagus nerve、accessory nerve、 hypoglossal nerves (CN Ⅸ、Ⅹ、Ⅺ、Ⅻ) 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 31)-TSE)、vagus nerve(100% in 3D-CISS and 52.3% in 3I)-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.
