Abstract

A total of 30 healthy volunteers underwent magnetic resonance imaging (MRI) with T1 weighted (w.) 3D magnetization prepared rapid gradient echo (MP-RAGE), T2 w. 2D turbo spin echo (TSE) and T2* w. 3D constructive interference in steady state (CISS) sequences to evaluate the detectability of the optic, oculomotor, trochlear and abducens nerves. CISS yielded the best results for the trochlear and abducens nerve, MP-RAGE for the optic chiasm and tract. The optic and oculomotor nerves were very well detectable using both CISS and MP-RAGE without any statistically significant difference between the two.

摘要

共有30名健康志愿者接受了磁共振成像（MRI）检查，采用T1加权（w.）3D磁化准备快速梯度回波（MP-RAGE）序列、T2加权（w.）2D涡轮自旋回波（TSE）序列和T2*加权（w.）3D稳态构成性干扰序列（CISS）来评估视神经、动眼神经、滑车神经和展神经的可检测性。CISS对滑车神经和展神经的成像效果最佳，MP-RAGE对视交叉和视束的成像效果最佳。使用CISS和MP-RAGE均可很好地检测到视神经和动眼神经，两者之间无任何统计学显著差异。
