结果对照组和患者的 T2 MRI 图像均显示出两块目标肌肉 GG 和 IL，以及患者手术留下的残留疤痕，正如预期的那样。在对照受试者中，舌隔膜位于中线，并将 GG 对称地分为左右两半。 IL 肌肉位于每块 GG 肌肉的侧面。另一方面，在该患者中，隔膜和两个 GG 都向右偏斜，并且失去了正常舌头中看到的扇形特征。相反，舌体中有一个黑色的不对称图案，与切除组织和手术初次闭合的区域一致。DTI 纤维束成像显示 IL 发生重大变化，但 GG 变化不大。对照中的大多数 IL 束呈水平且前后方向（绿色）、对称且厚度相似（图 1）。患者的IL表现出更显着的变化。右侧 IL 更薄更短。它的中断与 T2 图像中的疤痕组织一致。尽管大多数左侧 IL 束是前后向的（绿色），但也有一些束具有左右方向（粉红-红色）。最粗的红束（白色箭头，图2）描绘了一些前后方向的变化
ResultsT2 MRI images for both the control subject and patient showed two target muscles, GG and IL, and the residual scar from the patient’s surgery, as expected. In the control subject, the tongue septum was at midline and divided the GG symmetrically into right and left halves. The IL muscles were lateral to each GG muscle. In the patient, on the other hand, the septum and both GGs were deviated to the right and had lost the fan-shaped characteristics seen in normal tongues. Instead, there was a dark asymmetrical pattern in the tongue body that coincided with the area of excised tissue and surgical primary closure.The DTI tractography showed major changes in the IL, but little change in GG. Most of the IL bundles in the control were horizontal and oriented anterior-posterior (green), were symmetrical, and presented similar thickness (Fig 1). The patient’s IL showed more striking changes. The right IL was thinner and shorter. Its interruption coincided with scar tissue in the T2 image. Although most of the left IL bundles were anteriorposterior (green), there were several bundles with right-left orientation (pink-red). The thickest red bundle (white arrow, Fig 2) depicted a direction change of some anterior-posterior
