我们比较了16例肌萎缩侧索硬化（ALS）患者和20例对照组患者的舌磁共振图像，发现ALS患者的舌比临床上怀疑的更频繁和更严重，其大小，形状，位置和内部结构都有重大异常。在矢状面测量，ALS患者的舌头大小可以减少到正常的三分之二。ALS患者的舌头形状倾向于矩形或正方形，而不是正常的弯曲。随着疾病严重程度的增加，舌头的位置发生变化，使得大部分肌肉福尔斯远离门牙，不再与软腭的硬部接触。从口腔前底到粘膜表面的正常放射状带在LAS中经常缺失，平行于粘膜表面并与放射状带相交的两条曲线带也是如此。此外，舌的内部结构有斑点状的紊乱，信号强度增加和减少。
We compared the magnetic resonance images of the tongue of 16 amyotrophic lateral sclerosis (ALS) patients with those of 20 control patients and found the tongue in ALS patients is more frequently and more severely involved than suspected clinically, with major abnormalities of size, shape, position, and internal structure. The tongue size in ALS, as measured in the sagittal plane, can be reduced by as much as two-thirds of normal. The shape of the tongue in ALS tends to be rectangular or square rather than curved as is normal. As severity of the disease increases, the position of the tongue changes so that the bulk of the muscle falls away from the incisors and no longer is in contact with the hard of soft palate. The normal radial bands from the anterior floor of the mouth to the mucosal surface are often missing in LAS as are the two curvilinear bands that run parallel to the muscosal surface and intersect the radial bands. Also, there is a mottled disorganization of the internal structure of the tongue with areas of increased and decreased signal intensity.
