摘要:

 

弥散张量纤维束成像可帮助临床医生找到一些常规影像学检查所难以发现的神经纤维束损伤,因而其广泛应用于临床,以精确诊断神经系统疾病。

我们报道了1例左侧小腿围明显小于右侧,分别为26.0 和27.5 cm,且伴有左侧上下肢轻度肌无力的8岁女童;未发现其他神经系统症状。电诊断、常规脑和脊髓MRI未发现异常。皮质脊髓束和皮质网状束通路是控制自主运动的最重要神经纤维束。我们应用弥散张量纤维束成像评估了该女童的皮质脊髓束和皮质网状束,结果发现右侧皮质脊髓束和皮质网状束明显较左侧细。由此认为,该女童出现单侧肢体肌无力是由变细的皮质脊髓束和皮质网状束所致,肌无力的出现可能与小腿围变小有关。

Abstract:

In clinical practice, it is challenging to elucidate the location of the lesion in a patient’s nervous system that is causing the neurologic symptoms, because lesions are often microscopic and cannot be revealed by conventional evaluation methods.However, recently developed techniques may aid clinicians in detecting these microscopic lesions. In particular, diffusion tensor tractography (DTT), derived from diffusion tensor imaging (DTI), possesses the unique advantages of allowing three-dimensional visualization and estimation of neural tracts (Jang and Kwon, 2015; Kim et al., 2015; Chang et al., 2016). Several previous studies have demonstrated that DTT can detect hidden neural tract injuries in various disorders (Jang and Kwon,2015; Kim et al., 2015; Chang et al., 2016). Therefore, DTT is
being widely employed to accurately diagnose patients with neurologic symptoms.
