To assess a 3D high-resolution IR-prepped fast SPGR high-resolution MRI sequence for evaluating hypoglossal nerve lesions.
The clinical data of 8 patients with hypoglossal nerve lesions admitted from December 2011 to February 2016 were retrospectively analyzed. MRI included contrast-enhanced conventional sequences and a 3D IR-prepped fast SPGR high-resolution T1-weighted (BRAVO) MRI sequence at 3T.
Eight patients had hypoglossal lesions detected by MRI. Conventional enhanced scanning could not clearly display the hypoglossal nerve and canal, while the enhanced 3D high-resolution sequence could. In addition, multiple planar reconstruction clearly displayed the hypoglossal nerve, hypoglossal canal, and lesions in multiple planes.
Compared with conventional MRI, we show superior results from an advanced sequence to improve image quality in characterizing hypoglossal nerve lesions.
评估一种用于评估舌下神经病变的三维高分辨率 IR 预饱和快速 SPGR 高分辨率 MRI 序列。
回顾性分析 2011 年 12 月至 2016 年 2 月收治的 8 例舌下神经病变患者的临床资料。MRI 包括增强常规序列和 3T 下的三维 IR 预饱和快速 SPGR 高分辨率 T1 加权（BRAVO）MRI 序列。
8 例患者经 MRI 检查发现舌下神经病变。常规增强扫描不能清晰显示舌下神经和神经管，而增强三维高分辨率序列可以。此外，多平面重建可清晰显示舌下神经、舌下神经管及多个平面的病变。
与常规 MRI 相比，我们展示了先进序列的优越结果，可改善舌下神经病变的图像质量。
