Abstract/OtherAbstract:
ABSTRACT The anatomic localization of brain functions can be characterized via diffusion tensor imaging (DTI) in patients with brain tumors and neurologic symptoms. The goal of the present study was to evaluate the function of the ventral, arcuate fasciculus (AF) and the superior longitudinal fasciculus (SLF)-related language pathways using these techniques by analyzing nine patients treated in our hospital between 2007 and 2011. In Cases 1-3, the left ventral pathways, namely the inferior longitudinal fasciculus (ILF), uncinate fasciculus (UF), or inferior fronto-occipital fasciculus (IFOF), were mainly damaged, and the common dysfunction experienced by these patients was a deficit in object naming. In Cases 4-6, the left SLF was mainly damaged, and the common deficit was dysgraphia. In Cases 7-9, the left AF was mainly damaged, and almost all language function related to phonology was abnormal. These results suggest that the left ventral, AF and SLF-related pathways are closely related to visual, auditory, and hand-related language function, respectively.
