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.
